NAD C162/C272 Problems!
|
Bronze Member Username: BcollinsRockport, MA United States Post Number: 12 Registered: Nov-05 | Had to return my new NAD's. Was getting static/hiss through speakers with volume all the way down. Also, low level music still comming through when volume all the way down. Could get it to stop temporarily by moving pre-amp around a few inches in different directions in relation to amp. Has anyone else had this problem? Spoke with NAD tech support, did some trouble-shooting, switched cables, sources etc. but could not fix. Did not have problem through headphone jack however. Technician recommended returnig for replacement since it was still within the dealers 30 day return policy. Would like to get replacement but don't want to go through another return if this is a wide-spread issue. Any feedback would be appreciated. Thnk you, Bill |

Bronze Member Username: BcollinsRockport, MA United States Post Number: 13 Registered: Nov-05 | Thanks for the sympathy Nuck. You're right, "better now than later". Are you aware of any reliability problems with NAD? I thought they were supposed to be of good quality, but I've seen a couple of references on this forum indicating some problems with reliability. I realy like the sound, so I hope to replace the returned units, but I don't want to get into a situation where I am repeatedly sending them in for repair. Bill |

Rantz Unregistered guest | Bill, Have had the C162/272 combo for three days now playing almost constantly - no problems whatsoever in fact I believe it is worth every cent. The silence when the music pauses is ink black and the sound coming through the 602S3's is outstanding. These things have been out for a while now so if there was any abnormal number of problems I'd think we know about it from the forums. Get a new one and enjoy. |

That sounds like an issue with the pre, perhaps a relay ? I own the c272, also a 541i and c422, not a problem and the sound coming out of my polk lsi-9's is warm and smoooooooth.. Like the others have said, better now than later, get replacements and rock on... |

Silver Member Username: DanmanQUEBEC CANADA Post Number: 589 Registered: Apr-04 | First of all, low level sound with the volume all the way down is normal. I asked and checked other brands and they all due this do to the high current. As for your problems, I find this rare but it can happen. I owned Hondas and Toyotas all my life until recently buying Mazda and it has been the most trouble free car I have evr owned! This is not a NAD issue but more bad luck than anything! I am sure when you change them, all will fall into place. |

Gold Member Username: Jan_b_vigneDallas, TX Post Number: 6657 Registered: May-04 | Do to high current? There should be no current without a signal. This would indicate a problem of poor switching to me. Are these units with mechanical or electronic switching? |

Silver Member Username: DanmanQUEBEC CANADA Post Number: 590 Registered: Apr-04 | Boy, I sure put my "due's" and "do's" backwards!!!!!! What I meant was that I have asked this question of low level sound even when the volume is at a complete 0 and noticed this happens with many brands that are mid or higher fi. I am no technician but I have a friend that owns 50000$ of YBA gear that does the same! He said it was because of high amperage or something of that nature! Please don't quote me but I have heard other brands do this since my NAD gear has always done the same even after 1 1/2 of ownership problem free. |

Bronze Member Username: BcollinsRockport, MA United States Post Number: 15 Registered: Nov-05 | Thanks for the feedback everyone. Just to clarify, when I moved the pre-amp around in various directions above the power amp the static hiss would go away as would the low level sound and the peakers would then be dead quiet-no sound at all. If I moved it again or even just left it alone, eventually the static hiss and low level sound would return. It all depended on the postion of the pre-amp in relation to the power amp. This did not happen for the first week or two after I bought the NAD's. Bill |

Silver Member Username: DanmanQUEBEC CANADA Post Number: 591 Registered: Apr-04 | That is very strange! Mine never did this and I know others that have them without this problem. Don't worry, when you get new ones this will all go away. |

Silver Member Username: Sun_kingLeeds, West Yorkshire UK Post Number: 300 Registered: Mar-04 | I've been running a C160/C270 pair for over a year with no such problem. Also had the C162/C272 set for a week or so, again with no problem. Perhaps you had a duff piece of equipment. What leads did you connect between pre & power? Do you have your hifi near to any electrical devices that could cause interference? You are supposed to locate the pre-amp as far away from the power amp as is possible, ie not have them stacked directly on top of one another. This is to make them as un-combo like as possible (the whole point of having separates is to keep the power supplies apart) - you want to get the full benefit of having separate boxes. Having said that, that still shouldn't create the problem you describe. |

Silver Member Username: NuckParkhill, Ontario Canada Post Number: 481 Registered: Dec-04 | But thats me alright. |

Silver Member Username: NuckParkhill, Ontario Canada Post Number: 482 Registered: Dec-04 | King, the discrete power of the pre will(should) not be able to influence any other circuit, especially one a s heavy as the amp. However, a poorly insulated coil in teh torroidal could influence the pre, although those circuits are pretty well off frequency with anything else. But sometimes its plug in and find out, i suppose. |
