I don't hear a difference in amplification unless the amp is running at or beyond its design limit. That condition will be reached much sooner by a lower powered unit.
I have both a SS AVR & a lower powered Tube Amp for music only. I don't hear any difference in quality as long as they are driven within reason. Despite what the 'Tubies' say, I don't hear the claims of liquid highs, luscious mids & silky bass with a hint of cedar with overtones of honey. Both types sound the same to me with the same source material; however, 'toobz' are cool & I like being in the room with them basking in their glow.
Speakers make the biggest difference to me...
