Higher power=better sound at low volume?

This subject has been on my mind for a long time. I now have Wilson Sophia,series 2--Had the 1's before.(I think the upgraded 2's are better in the hi mid to upper high range) Now back to a power amp. I should mention I am an apt. dweller so low-volume is a constant way of life for me. I choose the Soph' for its ease of drive (Think; i.pod demo)and less fussy placement,qualities.
I was considering Pass 250.5 or 350.5. I was so confused about sound quality between the 2, I never bought either. I now have a Belles Ref 150 and even they make a 350 ref which I have pondered. I love what I have now but the speakers are still at around 200hrs of use and I figgure I should wait till they have at least 500 or more hrs on them.
So this thread re. someone's 150/250 vs their higher powered version has peaked my interest.
From what I have read, I love everything about the Lamms,'cept the price.BTW, this combo I have now it the best I have ever owned,but---?

Albertporter, FYI, Atma-sphere's smallest amp is their S-30, [30 wpc], although this is a stereo amp, and not a pair of mono-blocks, like the M-60.

The "big boy" is the MA-3, rated at 475 wpc! There are several unique features, including "on the fly" individual tube testing! Here is a link for the MA-3 Amp

I happen to think that Ralph Karsten is a remarkable designer, as well as a remarkable human being! He is one of the last truly independent manufacturers, having a long and proud company history.

Getting back to the question at hand, for SS operating in class A/B, I always went with an amp rated at or above maximum rated speaker power. For SS pure class A, I used an amp rated at 50-75% of speakers rated power. For tube amps, 50% of the speaker's rated power, even less sometimes, if the tube amp was operating pure class A. Just my general rule of thumb, tailored to my own listening preferences.

I think Audiokinesis brought up an important point about playing music at lower volumes: the lower the volume the less bass and treble the human ear/brain perceives in relation to the midrange frequencies. This is compensated for with switches on a lot of mass market equipment ('loudness' switches, etc.) but never seen on the higher end preamps and integrateds.
I definitely agree, though, that each amp/speaker combo has its own sound or personality regardless of wattage.

I knew that Chubbyparrott :^),

I was mostly trying to make a point about sound while reminiscing over the Atma-Sphere's I've owned. Just recently sold my mono M60's although It's been a long time since my MA2's.

No MA3's for me, I have to pay the electric bill around here. Can you imagine those in the summer here in Texas?

Now return here with some Parrot jokes, this thread is getting WAY too serious.
