I am inclined to "all amps sound the same" view (but not dogmatically so). Perhaps the real issues in selecting one amp/receiver over another is: the quality of components (do they use high-heat tolerant capacitors, etc); how effective is their heat dispersion/ventilation, how well isolated are the various modules from each other cross-talk wise, etc?
I have a NAD T775 HD which has been repaired twice in approx 5-7 years, and my repairer mentioned observing heat damage to some parts. I also read in some thread that this particular model NAD did have a bad area in terms of heat dispersion.
When I chose an earlier model NAD (T762) for my first receiver, I took it home together with a Denon (cannot remember model) of similar price, and would have sworn that the NAD had a "fuller"(???) sound. Like the NAD was a quality brand cello being played by a maestra, while the Denon was a cheap student's violin being played by a beginner. Hence my qualification "(but not dogmatically so)"so above.
Interestingly enough, my current NAD (the T775 HD) did not, to my ears, appear to have that odd sound "signature" as the earlier T762 had, but nor does it make everything sound thin in the way that Denon sounded. Don't get me wrong, I aint anti-Denon. Have had a Denon stereo amp as part of my first serious sound system, along with a Denon CD player, and also owned a Denon DVD/CD/SACD/DVD Audio player. Beautiful picture and sound quality, all of it.
In fact, my 20 + yr old Denon Stereo amp is still with me, and working, and indeed filled in (in stereo only) while my NAD T 775 was away for repairs, while my T762 is also having probs (I think the main control processor module - once it has been on for 5-10 minutes, nothing can be changed - volume, input source, surround mode - etc are non-responsive from both the remote and the buttons on the receiver front panel. Whatever settings you started with, you are stuck with.)
I'm rambling. I'll go. Time for breakfast anyway. (it's old age, I keep telling you.......)
