Based on recommendations here, I ended up getting a setup with the NAD C325BEE and a pair of PSB T45's. I'm looking to get a new system now, and I'd like to get a pair of speakers that have really great bass performance. I'm planning on using these speakers with the NAD C375BEE. (Note: not with my current C325BEE). I would appreciate any recommendations. Thanks! Also if anyone feels I should be using something other than the C375BEE please also let me know! |

New member Username: Rj85mail1Post Number: 2 Registered: Apr-10 | I'm just curious, how come the McIntosh has a rated distortion of 0.5%, while the C375BEE has it rated at 0.009%? Is McIntosh being more conservative than the other in ratings? Or do these numbers not mean much? I would expect the tube amp to have less distortions, and I should probably go to a local shop to hear the differences. |

You might, however, begin to wonder just how some manufacturers arrive at such low THD specs. It's fairly easy to design for a piece of literature which doesn't always lead to good sound. In actual use the Mac will probably have 0.01 THD for most of its frequency and power range. . |

I wouldn't say the spec is totally meaningless, but it's almost meaningless. Also, some types of distortion are more musical than others. Tube gear pretty much always has higher distortion specs than SS gear. The only measurement that really matters is how much you enjoy a piece of equipment, if that's a measurement. Hear some gear before committing to buying anything. It sounds like you like the NAD gear, so buying a model or two up thier line seems reasonably safe. While that may make sense, most often you're getting more of the same. Without knowing what your looking for - space limits, sound characteristics, budget, etc., it's pretty hard to recommend anything. What is it about the current system that isn't doing it for you? What source or sources are you using? Is everything set up properly? |

" Intermodulation distortion (I.M.), the distortion (ie, a third tone) product of two frequencies simultaneously injected into the circuit. "More important, fig.5 reveals that the distortion spectrum consists almost entirely of subjectively innocuous low-order components, though a comparison of the spectra at high power into 8 ohms (fig.6) and 4 ohms (fig.7) indicates that the third harmonic rises as the output current increases. Note, however, the very low level of AC supply spuriae in these graphs. The 7B SST2's power supply is clearly more than adequate for the high powers this amplifier is designed to deliver. Finally, when tested at close to clipping into 4 ohms with the demanding combination of 19 and 20kHz tones, the Bryston's output spectrum (fig.8) was more like that of a preamplifier, with all intermodulation products at or below --100dB (0.001%)." http://stereophile.com/solidpoweramps/bryston_7b_sstsup2sup_monoblock_power_ampl ifier/index7.html . |
