just a quick update but I did a few more casual tests with some other family members (brothers in law, etc) and was as careful as possible not to say anything that would bias them. Everyone so far, unprompted, has said the same things about the two amps.
I wanted some other opinions just to make sure I’m not crazy, and everyone has described the luxman’s output as more lifelike and vibrant (referring to the clarity of the mids and highs relative to the sound of the Accuphase) - one brother in law said amp A was like looking directly at the music , amp b was like looking at it through a window.
@ddude interesting you’ve seen this before too. Maybe it’s a real phenomenon that just isn’t acknowledged much?
@charles1dad @atmasphere I’ll let you know if I have a chance to test with any other kinds of amps.
