reminds me of the "audiophile" in a forum who wrote that good amplifiers need a warm up time of 2 weeks before they sound good, that's how long it takes for the temps to stabilize in an amp.

i thought that as he uses the amp, its temperature would vary all the time as a function of varying power output, and thus would destabilize the amp and produce distortion.

but what do i know, i'm not a golden eared audiophile who can discern the difference between 0.0025% and 0.0000025% THD in an amp.

Yesterday morning i installed a new QSC GX5 amp (to replace a Hafler 500 which will go to surround duty).
After about 6 hours of concentrated listening of different program material, i could not hear any difference between the 2 amps, and i let the amp "warm up" for only a few minutes.
