Denon on fire
|
New member Username: Kay123Post Number: 2 Registered: Dec-08 | I have a Denon receiver which heats up pretty fast. Any ideas as to how to control the heat? Thanks |
|
New member Username: OnecallPost Number: 10 Registered: Dec-08 | Ben, What model receiver to you have and what speakers are you using with your receiver? |
|
Silver Member Username: SoundgameRichmond Hill Toronto ..., Ontario Canada Post Number: 475 Registered: Jun-08 | Have you got sufficient ventilation above and to the sides, if so and it isn't cutting out on you, then it's probably not too much to be concerned with but share the model and details of under what circumstance you find it heating up. I have an Onkyo 805 AVR myself and it gets quite hot when running at low volume levels or sitting idle; however, if I run it an moderate volume level it gets a little cooler. She's been working fine with no issues whatsoever for almost a year. |

New member Username: Kay123Post Number: 4 Registered: Dec-08 | I have Denon AVR 3808ci; and I use it paradigm speakers. |
|
New member Username: Kay123Post Number: 5 Registered: Dec-08 | It heats whenever I use it, but if I turned the volume high, it becomes so hot that it ceases to play until it has cooled down. I always make sure there is enough ventillation around it. |

Silver Member Username: MagfanUSA Post Number: 391 Registered: Oct-07 | Sounds like your Denon really don't like dem Paradigms. If you gotta have this setup, you can either used forced air, turn it down or replace the Denon every couple years. You're cookin' it. |

Platinum Member Username: NuckPost Number: 11343 Registered: Dec-04 | Ben, this will annoy you only once or twice more, then it won't matter cause it will be dead. |
|
New member Username: Kay123Post Number: 6 Registered: Dec-08 | Given my situation, what are the best receivers for paradigm speakers? |
|
Bronze Member Username: OnecallPost Number: 11 Registered: Dec-08 | Ben, The receiver is shutting down due to the protection circuit kicking in from the extreme heat. Although the Paradigm speakers I've looked at indicate they are compatible with 8 ohms they may still be putting an excessive load on the amplifier causing it to run to hot at high volumes. Before you consider upgrading there are a couple of questions I would ask that would give you more information. 1. What model speakers do you have from Paradigm and how long have you owned them? 2. Does the receiver shut down at high volume levels with only two speakers playing? e.g. Listening to stereo music, preferably CD rather than MP3 or radio. 3. What are you using for speaker wire? Matt @ OneCall |
|
New member Username: Kay123Post Number: 7 Registered: Dec-08 | My paradigm speakers are: studio 20, cc-590, ADP 590 and Seismic 10. I have used the speakers for less than a year . I got my speaker wires from Best Buy -- I guess ordinary speaker wires, but the wire for the Seismic 10 is thicker. The receiver shuts down at high volume levels when playing with all 6 speakers. |
|
Bronze Member Username: OnecallSpokane, WA Post Number: 14 Registered: Dec-08 | A Very nice system. However Leo and Nuck are on the right track, each time the protection circuit is tripped it will become easier and easier to trip until the receiver is completely "cooked". Although the specs for the speakers indicate "Compatible with 8 ohms" they may be more than the receiver can handle. If you really want the best sound from your speakers I would suggest adding a 5-channel power amplifier to power you speakers instead of upgrading the receiver. There is an extensive list of benefits to having a separate amp for power especially when considerig the caliber of speakers you have. Let me know if you would like a recommendation. Matt @ OneCall |
|
New member Username: Kay123Post Number: 8 Registered: Dec-08 | Do you mean adding an amplifier to the receiver? Please go ahead and give me the recommendation. Thanks |
|
Bronze Member Username: OnecallSpokane, WA Post Number: 15 Registered: Dec-08 | Correct, your receiver has pre-amplifier outputs. You could add something like the Adcom GFA-7605 amplifier http://www.onecall.com/ProductDetails.aspx?id=17203&BCPID=200 The other alternative would be switching the receiver to the Onkyo TX-NR906 http://www.onecall.com/ProductDetails.aspx?id=92775&BCPID=200 Which is compatible with lower impedance speakers and costs about the same as the AVR-3808CI. It would still run hot because of the higher current amplifier, but should not shutdown. I hope this helps. Let me know if you have any other questions. Matt @ OneCall |

Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1887 Registered: Feb-07 | Sounds like a you have a nice setup Ben. I just picked up a pair of Studio 20's this week. Definitely sounds like your Denon is being overworked, although I find it surprising that your Paradigms are causing the Denon to overheat. The Paradigms are pretty easy speakers to drive. Just how loud are you listening to your system? |
|
Silver Member Username: MagfanUSA Post Number: 399 Registered: Oct-07 | OneCall may be on to something: If you are using cheesy speaker wire OR have bad/ oxidized connections, that'll be problems. I'm not going to make a specific recommendation, but you should at least check what you are now using. Thin wire in longer runs is a deal breaker. Is the receiver clean inside? A good clog of dust-bunnies will do this, too. |
|
New member Username: Kay123Post Number: 9 Registered: Dec-08 | I am going to change the speaker wires first before considering OneCall's recommendations. I went to Denon USA website yesterday and found out that "shorted" speaker wires can cause a receiver to shut down. |
|
Silver Member Username: SoundgameRichmond Hill Toronto ..., Ontario Canada Post Number: 485 Registered: Jun-08 | Ben, Also verify that all the speakers you have hooked up to the receiver have a nominal resistance rating of 8ohms. If any of the speakers are rated at 4ohms, you need to change the seting on your receiver to output into 4ohms - this will result in the power output level on the receiver being limited but should help to reduce the chance of it shutting down. |
|
Bronze Member Username: OnecallSpokane, WA Post Number: 16 Registered: Dec-08 | Ben, You are correct, shorted speaker wires can activate the receiver's protection circuit but from what you've described that's not the first diagnosis that comes to mind but there are ways to test it. Like Leo says, if you have a corroded speaker wire(s) or a very small gauge speaker wire it can cause problems in the system. A few things I seen that have caused issues like this: 1. Improper ventilation: but you say you have plenty of space around the receiver. 2. Improper impedance/resistance from the speakers. Your receiver is only compatible with 6-16 ohm impedance speakers. Your Paradigm speaker specs all indicate they are "compatible with 8 ohms". (Your receiver will only handle a 4 ohm impedance for a limited time period or it will overheat and shut down) 3. A Short in a speaker wire: easiest way to test is use the manual speaker setup to turn off the Center & surround channels listen for a while then turn on the center speaker and listen again, then turn on the surround speakers. An example; if you turn the center and listen for a while and the receiver shuts down you've just narrowed it down to the center speaker or speaker wire. 4. A short in one of the speaker drivers: During the process above, if one speaker is causing the receiver to shut down try a different speaker wire, if the receiver still shuts down it is most likely the speaker. 5. Small gauge speaker wire: You don't have to go to any extremes with the speaker wire, a good quality speaker wire (I would usually suggest a minimum 14g wire) should be sufficient. Years ago I actually witnessed a Kenwood receiver burn itself up in the space of about 5 minutes because someone used insufficient quality speaker wire. 6. Current limiting power supply: Rare but happens occasionally. Some power surge protectors will limit the amount of current that can be drawn from the wall outlet which means that in some occasions the receiver can't draw enough power to work as efficiently as it should. This can cause the receiver to shut down. The easiest way to test this is to plug your receiver TEMPORARILY directly into the wall outlet, not the surge protector and play the system at a higher volume level to see what happens. For what it is worth I think you're right to do some more trouble shooting before rushing in to anything else. Matt @ OneCall |

Silver Member Username: MagfanUSA Post Number: 402 Registered: Oct-07 | Link to Stereophile test of Paradigm Studio 20s. This is the measurment panel. Please note impedence/phase angle data and comments: http://www.stereophile.com/budgetcomponents/508para/index4.html Low and high phase angle tell me the Denon (6ohm min, probably) won't be a terrific match, especially at medium and higher loudness: |
|
New member Username: Kay123Post Number: 10 Registered: Dec-08 | Leo, Thanks for the information. Could you please give me the names of receivers that will match the paradigm speakers. |
|
Silver Member Username: EramseySouth carolina United States Post Number: 606 Registered: Feb-05 | Only a few Ben-HK,NAD,Some Yamaha,Some Onkyo and a few upper end Marantz, of course this still leaves the issue of which of these will sound best to you with the Paradigms. |
|
Platinum Member Username: NuckPost Number: 11375 Registered: Dec-04 | Rotel and Paradigm 20's are good as well, I think Art had fun with this setup. |
|
Platinum Member Username: NuckPost Number: 11376 Registered: Dec-04 | My bad, not a receiver. |
|
Silver Member Username: SoundgameRichmond Hill Toronto ..., Ontario Canada Post Number: 510 Registered: Jun-08 | The Onkyo 8 series i.e. 805, 875 or 806, 876 will be able to drive those Paradigm's or you could look to the Integra line. That said, you're not going to get all you can out of those Studio20's with an AVR. With the Onkyo's you have preouts so you could always add a two channel amp to get more out of the Paradigms. The Onkyo's and Integra's work very well as preamp/processors. |
|
Silver Member Username: SoundgameRichmond Hill Toronto ..., Ontario Canada Post Number: 511 Registered: Jun-08 | To tell you the truth, I'm not sure why the Denon 3808 is having a problem. Have you tried calling Denon and asking them what could be happening? In addition, you could always use the 3808 as a pre/pro and just add a power amp. |
|
Platinum Member Username: NuckPost Number: 11379 Registered: Dec-04 | If the 3808 is selectable, I would go for the 8ohm outputs. |
|
Bronze Member Username: Kay123Post Number: 11 Registered: Dec-08 | OneCall is right about adding an amplifier to the receiver. I called Denon today, and the agent said that i should get an amplifier and connect the front speakers to the amplifier to reduce the load on the receiver. |
|
Silver Member Username: SoundgameRichmond Hill Toronto ..., Ontario Canada Post Number: 515 Registered: Jun-08 | Denon gave you the safe answer, which is to direct you to buy additional product to make up for the shortcomings of their product. Yes, if you had a powerful amplifier AND there is nothing wrong with the wires or the Denon AVR, then it will work. However, if the Denon is faulty and is shutting down for other reasons, you're still going to run into problems. At reasonable volumes (under 10% clipping/under 1% THD) your Denon AVR should be able to drive a those Paradigm's all day. Just how loud are you trying to drive them? This usually doesn't matter but for interest sake, how high is the volume (what's the number on the dial when it's shutting down). As safe volume should be at the reference volume, which should be 0 on the dial, when you have the AVR calibrated. If you calibrate the AVR using the supplied microphone, you should be able to leave it at the ref. volume of 0, all day without it shutting down. I'm saying all this because I don't want you to spend the extra money on an additional amplifier, unless that's what you really want. An additional amp. if of high quality will give you better sound and better dynamics. So, if you have the money and don't want to look into the real problem behind the Denon, then go with the amplifier. I run my Onkyo 805 with a Bryston 3B-ST power amp. but NOT because it shuts down at high volumes with 8-ohm speakers (because it never has) but because I wanted to get to the next level in terms of clarity, dynamics etc. Let us know what you decide to do but start with following the recommendations of checking your connections, settings, wires and doing the calibration AND finally running that thing at reference levels and not at the MAX. volume setting. Cheers and all the best with it. |

Bronze Member Username: Kay123Post Number: 12 Registered: Dec-08 | George, I normally use the system at a very low volume levels. It is when I am having a party that I run into this problem...you know during a party you cannot operate the audio system at low volume levels. One of the things the Denon agent said was because my speakers has an impedence of 4 ohms, they were putting a lot of load on my receiver. I asked him if the receiver has a selectable device to allow me to switch the receiver to 4 ohms. He said, no. I have checked the speakers and the receiver and none of them is faulty. I am yet to decide whether to add a power amplifier to the receiver or sell the receiver and purchase a different receiver..obviously not a Denon |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1939 Registered: Feb-07 | Hey Ben, if you're intent on hanging onto the Denon, why not pick up a cheap 2 channel amp to drive your front speakers. This way when you have parties you can crank the system without it shutting down. Maybe like an old used NAD amp? Another thing... you mentioned: "The receiver shuts down at high volume levels when playing with all 6 speakers." Is this when listening to music or watching movies? If listening to music, why not listen in stereo mode? It'll sound better and the amp section will only be driving your 2 front speakers. |
|
Bronze Member Username: OnecallSpokane, WA Post Number: 20 Registered: Dec-08 | Ben, George is right, Denon gave the safe and easy answer since the person you were speaking with may not have been familiar with your Paradigm speakers and there isn't any more information for trouble shooting the situation in their owner's manual. There is one other thing that came to mind that you could look at. If you've run the Audyssey auto setup you may want to take a look at the speaker size settings and crossover settings. It is possible that the Audyssey setup may have set your Left, Center, Right and Surrounds speakers to large with full range output due to the frequency response of the speakers. With your On Screen menu got to Manual Setup -- Speaker Setup. Under Speaker Configuration if your speakers are all set to Large I would suggest making the following adjustments and test the system to see what happens. 1. Set your Left, Center, Right and Surround speakers to Small (the large setting disables the Crossover Frequency settings). 2. Again under the Manual Setup -- Speaker Setup menu you'll have an option for Crossover Frequency. After reviewing the specs for your speakers I would suggest setting the crossover for all the speakers to 80HZ. Yes, I know this is not an ideal solution because you really won't get the full performance from your speakers. If it works it is much more cost effective than buying a new receiver or a power amplifier. Now, to give you a simple answer so you know why I'm suggesting these settings, I'm sure there are more than a few members on this forum that could give you a more technical answer. The impedance or resistance of a speaker will vary depending on the frequency it is producing. By limiting the frequencies sent to and produced by the speakers may help to reduce the resistance on the amplifier in your receiver which may help keep it from overheating. Like I said, check the current settings in the speaker configuration menu and make the changes if they are not set that way already then crank up your system and test it out to see what happens. If it helps and your receiver no longer shuts down that's great, it just means the best upgrade you could make to your system in the future would be a power amplifier. I really hope this helps, I'm imagine you'd like to be able to enjoy your system without having to worry about it shutting down on you. Matt P Merchandising Specialist Matt.P@onecall.com |

Silver Member Username: SoundgameRichmond Hill Toronto ..., Ontario Canada Post Number: 517 Registered: Jun-08 | Ben, I think that you've got some good suggestions from Dave and OneCall. On Dave's point, he hit the nail on the head...never use you main system for parties. Too many amps and speakers go up in smoke after the women and the drinks get to your head...no pun intended. Get yourself a party system that sounds crap when you're sober but like an ugly lady, turns into a goddess when you've had a few. Even some old school power will do...like an old pioneer receiver, or JVC and the like. Then get yourself some big a.s.s. speakers with 10 or 12 inch woofers and hammer away at it. Leave the Denon and those beutiful Studio's to more sober use. BTW this is right from the 2004 SoundStage review of the Paradigm Studio20's: "Paradigm says the Studio 20 v.3's...anechoic sensitivity is rated as 87dB, while impedance is said to be "compatible with 8 ohms" -- an alternate way of stating the equally vague "8 ohms nominal," I guess. Translation: This speaker shouldn't give any reasonably powerful amplifier made to handle an 8-ohm load (they all are) any difficulty. In fact, I used the Studio 20 v.3 with Zanden's Model 600 30Wpc tube integrated amp, and it didn't give the amp the slightest bit of grief." These speaker should not give trouble with you Denon AVR, especially not a 3808CI at reasonable volumes.} |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1940 Registered: Feb-07 | That's what I was thinking George. I find it hard to believe that the Denon is choking on driving Paradigms at reasonable listening levels. I guess the keyword is reasonable? I'm still thinking that running your music in multichannel mode is putting too much stress on your receiver. I've driven 6 ohm speakers to insane levels with a relatively cheap Yamaha receiver with never any issues, always in stereo mode. |
|
Bronze Member Username: Kay123Post Number: 13 Registered: Dec-08 | I am leaning towards adding a power amplifier to the Denon receiver. OneCall suggested Adcom GFA-7605 amplifier; any other suggestions? There are other benefits that I will get from a power amplifier besides reducing the load on the Denon. |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1954 Registered: Feb-07 | There's definitely benefits to adding a power amplifier! What's the budget Ben? |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 531 Registered: Jun-08 | Bryston 3B or 3B-ST. This have a 20yr manufacturers warranty that's transferable, so looking for a good used one will save you some money. |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1955 Registered: Feb-07 | Dammit George! I was just gonna say that... you beat me to it. |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 532 Registered: Jun-08 | Yeah Dave, you were just trying to go about it in a professional manner, trying to get the clients needs prior to dropping the recommendation. I just went for the kill...LOL. No, seriously Ben, the Bryston's can be had for very good deals on the used market and the warranties are bullet proof. |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1956 Registered: Feb-07 | Next time I know to be quicker ;-) Brystons also retain their resale value nicely. |
|
Bronze Member Username: OnecallSpokane, WA Post Number: 22 Registered: Dec-08 | Ben, I'm sure the Bryston amps are very good although I've never had the opportunity to listen to one. Before you make your decision, take a look at the specs and power handling of your speakers. I know there have been a couple of recommendations in this thread for just a two channel amp I would actually recommend a 5 channel amp to power all of your speakes. That way you can spread the benefit of power amp to all of your speakers. Matt P Merchandising Specialist Matt.P@onecall.com |

Bronze Member Username: Kay123Post Number: 14 Registered: Dec-08 | I have a budget of up to $2000 and my speakers have a amplifier power range of 15-200 watts |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1957 Registered: Feb-07 | OneCall is offering some pretty good advice. A 5 channel amp would be a good idea. How about an Outlaw? http://outlawaudio.com/products/7500.html |
|
Bronze Member Username: Kay123Post Number: 15 Registered: Dec-08 | Eventhough I set my budget for a power amplifier up to $2000, I am prepared to increase it if the amplifier will deliver the "goods." I like what I read about Bryston 3B-SST, but I don't know how powerful it is. Right now, I am torn between Adcom GFA-7605 amplifier and Bryston 3B-SST. Those of you who have Bryston amplifier, could you please tell me more about it. Thanks |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 1960 Registered: Feb-07 | Adcom is not in the same league as Bryston. Bryston is extremely well built (like a tank) and hand-made in Canada. They are so confident with their product that they offer a 20 year transferable warranty on power amps. Their sound is clean, powerful and neutral, with plenty of attack while still having control over the music. You really can't go wrong. I have a 3B, BTW (and 2x2Bs', and 2 Power Pac 120 monos, and a BP-20... you get the idea). |
|
Gold Member Username: ArtkAlbany, Oregon USA Post Number: 8603 Registered: Feb-05 | I don't own a Bryston but have listened to them on numerous occasions. I have owned an Adcom some time ago. Comparing Bryston with Adcom is like comparing Oranges to artificial orange flavoring...they really aren't the same thing even though they may serve the same purpose. Bryston is in another class altogether. |

Platinum Member Username: GlasswolfRaccoon City, MI USA Post Number: 12209 Registered: Dec-03 | Ben, as to the OP, for what it's worth, AVS has a lot of threads on heat build up on that model and some similar receivers. I looked at the 3808CI and almost went with one when I chose the Onkyo NR906 instead, but both are reported to get very hot even during low volume typical TV watching use. The cause, according to AVSforums, is the video processing chipset, which apparently gets extremely hot in both of these receivers. One common solution is to put a fan behind the receiver to ventilate the hot air away from it (such as an 80 or 92mm PC fan) but this don't keep from heating up the room it's in of course. Best of luck. Nice receiver  I only really chose the Onkyo because it offered what the 4808CI has, at half the price. HD radio and Sirius support. |
|
Bronze Member Username: OnecallSpokane, WA Post Number: 35 Registered: Dec-08 | Ben, GlassWolf brings up an interesting point. If the Video processor is creating enough additional heat to cause the receiver to shut down there may be an easy way to test it. Your receiver has a "Pure Direct" mode which if I am correct essentially turns off the video processor, which could help reduce the heat it generates when you're only listening to music. (Check page 41 of your owner's manual for more info.) Keep in mind that when you activate the "Pure Direct" mode the front panel display, the on-screen display and I believe the video output signal are disabled. Also, for those parties when the remote may find itself in the hands of someone other than you, I would check pages 33-36 for the "Volume Limit" and "Power On Level". These are two very handy features of the receiver. If you haven't already set them you can set the maximum volume the receiver can be turned up to. The "Power On Level" can be nice for the day after it can be set to turm on at a lower volume level everytime you turn it on. Matt @ OneCall |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 533 Registered: Jun-08 | Nice suggestions Matt. I never thought about using the Pure Direct mode on my Onkyo. |
|
Platinum Member Username: GlasswolfRaccoon City, MI USA Post Number: 12214 Registered: Dec-03 | also consider the lock out mode if supported, to disable the menuing so people don't go messing with your settings. I know some receivers have that feature, I can't recall if Denon does. |

Silver Member Username: MagfanUSA Post Number: 405 Registered: Oct-07 | Sorry, but I want to go over some old ground.... Ben mentions buying speaker wire at Best. I was just there.....and checked out the wire selection. max size was 16 and than the 'Monster' stuff....which I'd avoid as overpriced/hyped stuff. Depending on length of run, 16 is inadequate for this application. Start at the start, before going thru a huge list of menu/setup options. |

Silver Member Username: MccambleyBREEZY POINT, NY USA Post Number: 578 Registered: Jun-05 | I have installed Denon and Paradigm Studio 20's together for the past 10 years at least 20 times and have never had a problem. Those are 8 ohn speakers and 8 ohm receivers. Is it possible that a stray piece of speaker wire is shorting out the system. Try adding banana plugs to the speaker wire for a cleaner connection. The amp ideas are great no matter if that the problem or not a better amp is always good and the Bryston are very good. |
|
Bronze Member Username: Kay123Post Number: 16 Registered: Dec-08 | Thank you all for your input in this matter. I have decided to get Bryston 3B-ST and as Casey suggested banana plugs for the speaker wires. Thanks once again. |
|
Platinum Member Username: GlasswolfNW, MI USA Post Number: 12299 Registered: Dec-03 | hey Ben if you do want to build your own speaker wires, take a look at www.knukonceptz.com they have nice banana plug sets for $7.99 (set of 4) and very nice home speaker wire for both in-wall and non in-wall applications. I really like their Karma SS cable, and it's very affordable. I used their cables and wiring to do my system, and have used it in many car systems as well. |

Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 575 Registered: Jun-08 | Ben, there's no going wrong with that 3B-ST, I own one myself. If you have the cash, the SST has even more to please the audiophile. |
|
Bronze Member Username: Kay123Post Number: 17 Registered: Dec-08 | I am set to buy Bryston 3B SST amplifier in a week, but I have also been thinking about OneCall's suggestion to go for a 5 channel amplifier to power all my speakers. Currently, I am torn between Bryston 3B SST and Bryston 9B SST. Is the Bryston 9B as powerful as the Bryston 3B? Will it be compatible with my receiver and speakers? |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 585 Registered: Jun-08 | Hey Ben...from the Bryston site: The Bryston 9B SST is a modular, five-channel, single-chassis power amplifier that delivers 200 watts per channel into 4 ohms or 120 watts per channel into 8 ohms. The 9B SST employs modular construction in which each channel is completely self-contained, physically and electronically, with independent I/O connectors, toroidal transformer and power supply. The only things individual channels share is the rack enclosure and the power cord. The Answer Is: Yes, yes ... you'll get all the power of the 3B since each channel is a separate mono amp with its own power supply. If you have the bucks...the 9B SST for 5 ch audio would be great. |
|
Bronze Member Username: OnecallSpokane, WA Post Number: 49 Registered: Dec-08 | Hi Ben, Like George says the 5 channel amp would be absolutely compatible with your receiver and speakers. I would stand by my original suggestion of a 5 channel amp because it simply makes sense with the quality of the speakers you have. If you're going to add an external amp you may as well get the same sound quality benefit from all of your speakers. Of course with what I've heard about the Bryston sound quality and speakers your have you may want to start selling tickets at the front door when movie night rolls around at your house. Matt |
|
Bronze Member Username: Kay123Post Number: 18 Registered: Dec-08 | Matt (OneCall) and George, Thanks again for your advice and timely manner you responded to my questions. I am going in for Bryston 9B SST. |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 590 Registered: Jun-08 | Let us know when you've got it home. Then you'll be shopping for new speakers to match. Cheers. |
|
Bronze Member Username: Kay123Post Number: 19 Registered: Dec-08 | Finally, the Bryston is in. It is very very heavy. I have not had time to install it; I hope to do so soon. |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 605 Registered: Jun-08 | So Ben, did you get the 9B-SST (brand new)? I can't see you not being happy. I'm very interested in hearing your impressions. What are you using it with? Will you be using the Denon AVR as your pre/pro? |
|
Bronze Member Username: Kay123Post Number: 20 Registered: Dec-08 | George, the Bryston 9B-SST is brand new; it was shipped from Canada. I have decided to connect my speakers to the Bryston, and then connect the Bryston to the Denon.Any suggestions? I am really excited about the route I have taken after a long discussion about what is right for my audio system. I have not connected the Bryston yet, however, I am happy I bought it.

Bronze Member Username: OnecallSpokane, WA Post Number: 67 Registered: Dec-08 | Hi Ben, I think you're on the right track with connecting the amp in your system. I also think you'll be very happy with the results. I'm interested to hear your thoughts of your system and the sound quality before and after the amp. Matt @ OneCall |

Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 607 Registered: Jun-08 | I myself am running an Onkyo 805 AVR as a pre/pro with a Bryston 3B-ST powering my front two channels. It works very well for music and is great for HT. The Bryston brought enhanced clarity, jaw dropping along with more punch and snap. I have no doubt you will find a night and day comparision in sound in comparision to running the Denon alone. One thing to note is that since your Denon will be acting as the pre/pro with no speakers hooked up to it, the interconnect cable you use between the Denon and the Bryston will make all the difference in the world...believe me, I've heard a considerable difference in sound based on the interconnect used. Don't go with Monster cable...at least not their entry level...didn't work well for me, at all. What will you be using for an interconnect? An interconnect brand which is relatively affordable and will give you good quality / neutral sound with your Bryston would be one from Blue Jeans. I haven't used it myself but have heard on this forum it works very well. Here's the link: http://www.bluejeanscable.com/ So, as you said, all speakers should be hooked up directly to the Bryston and use cables of 16 guage or less. Blue Jeans sells some quality/affordable speaker cable, as well but there are lots to choose from. I like both the entry level Tara Labs as well as Kimber Kable. What are you using currently? |

Bronze Member Username: Kay123Post Number: 21 Registered: Dec-08 | After adding the Bryston to my audio system, this is what I have observed: 1.The Denon receiver does not shut down 2.The Bryston warms up close to or above the warmth/heat the Denon produced just before shutting down, but does not shut down the audio system; obviously when playing at high volume levels. 3. The Denon now warms up just a little...I can say the amount of warmth produced is negligible. 4. The Bryston has added some amount of clarity to the sound quality. Even though the Bryston is expensive, if I had to do it over, I shall purchase the Bryston first, even before considering the Denon. |

Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2112 Registered: Feb-07 | My Bryston 3B gets insanely hot, but never even considers shutting down. My Bryston PP 120's I can run all night long and don't even get remotely warm. |

Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 628 Registered: Jun-08 | Go to hear Ben. You've got 20 to 30 years at minimum with that amp. and it is hard to beat at less than double that money. My 3B-ST only gets warm, I've never had it get hot. |

New member Username: Callahan90Ottawa, Ontario Canada Post Number: 2 Registered: Jun-09 | my denon 2808 heats up pretty bad, would an amp with more watts solve the problem? |

Bronze Member Username: OnecallSpokane, WA Post Number: 85 Registered: Dec-08 | Hi James, Without more details about your system like what speakers your using and and your other equipment it's hard to say for sure. Keep in mind that most high quality receivers will run warm to hot especially if it's run at a high volume for an extended amount of time. I'd be most concerned if you've had issues with the receive shutting down or going into the protect mode. Matt at OneCall |

Gold Member Username: Frank_abelaBerkshire UK Post Number: 3669 Registered: Sep-04 | The only things that should make a 2808 hot to the touch when in use are: 1. Ventilation (both beneath and above the unit). Ensure it's not on a carpet-like platform so it can draw cool air from below and ensure it has at least 3 inches above to allow the air to flow. 2. A short in the system. Speaker cables with an intermittent short can cause this kind of problem. If you have cats, check the speaker cable runs to see if any of them have been chewed. 3. Speakers which are difficult to drive. If you're using 4ohm speakers (should say on the back), these will use a lot more power than 6 or 8 ohm speakers. In this case, a more powerful receiver may be required, but only if the unit has had to shut down. If not, then it's working within tolerance and will continue to do so happily. Frank. |
