Differences don't particulary mean "better" tho and fully depend on specifics of room/setup/comparison details or what the hell are you comparing particularly except perhaps a preference?...
Who knows what he might feel "sounds" better even if its technically worse?
I didn't claim that difference means better. In fact, I argued the opposite (except in the case of the cheap old Sony, which I do claim was not only not as technically good but
also was less preferable in sound character compared to the other five receivers I played with). I also acknowledged my rooms, my setups, my ears, my purposes, my preference.
I certainly didn't claim the Pioneer Elite was technically better than the Marantz sr7015. They're both good. And I don't know, but I'd suspect the Marantz might "measure" better in some regards... but that's not my concern.
I don't sit around and obsess over the technical measurements of gear, because that's not the endgame for an audio-phile (lover of sound)... tech measures might be the endgame for a techno-phile, though (lover of tech).
I only observed that I did hear differences in the sound signatures, and found that I had preferences.
And, I was not alone in hearing
differences. And, the differences were obvious enough that even casual, non-audiophiles noticed spontaneously, without being "coached" by me.
I also found that I was surprised by the findings I experienced, but was willing to acknowledge that my previous assumptions were wrong. My previous assumptions were that there would be no discernible differences, or clearly preferable sound-signatures... preferable to me, in my circumstances, with my other gear. I found that there were discernible differences in sound
character,
not that one was technically better than the other except that one's sound character matched my preferences, my goals with my gear, better than another did.
It had been a long-cherished BELIEF of mine that amps really don't make a difference in how a system sounds; but
my own belief was challenged by my own recent experiences, and now I have to discard my old belief which I now believe to be incorrect. I now believe that there can be, indeed are, differences in amps' sound characters... at least some amps. Discernible generally as
technically better one way or another, once a certain level of overall quality is attained? Of
that I remain
skeptical. Sound character, sonic signature or whatever... yes, differences. At that point, subjectivity reigns, and it's a matter of preferences. Different amps for different speakers in different rooms and different configurations and different goals and for different ears, yes, differences and subjective preferences.
That's it.
