Onhwy61,
We don't disagree. We're talking about different phenomena.
I agree that "purist" recordings sound most lifelike within a certain volume range (though it's hardly a knife-edge adjustment). As classical listeners (and a little jazz), all of our good recordings behave this way.
They do not, however, suddenly become distorted or harsh when played back at other volumes.
Room acoustics can of course cause harshness/distortion of certain frequencies. But IME, when one PRECISE setting on the gain control tames the problem then a component is to blame. Room mode problems often ramp up with volume. They don't appear out of nowhere when the knob is twisted .1db too high.
We've experienced this with several (well known and non-cheap) amps and preamps. Our present equipment does not behave so. Since our room has stayed the same...
At any rate, we both agree that there's room for further improvement, even as he's enjoying his newly musical digital source.
P.S. I have a stock Denon 3910 and I've demoed an Underwood-modded one. I haven't heard the APL version but I doubt it's involved in this particular problem. Amp and/or preamp are more likely candidates.
