how does current work in an amplifier?

Tony, except that tube amps tend to be more expensive and high effiency speakers tend to need help extending the bass, which doesn't come cheap either.

Atmasphere, with all due respect there were other incentives such as convenience and reliability amongst others.

Atmasphere, of course many of find some ss amps offer a balance of both objective and subjective performance that is preferable. I am confident that many speaker designers welcome the opportunity to avail their design talents towards making speakers for those ss amplification attributes for the sheer performance opportunities those combinations provide.

Atmasphere, all very interesting, and if you could kindly provide a link, I'd very much like to read it. With that said, I'm curious as to who determined, and what are the "perceptual rules", at what point(s) are variances to these "perceptual rules" deemed "violations" and does it really matter at what part of the brain we get our enjoyment? In the end I consistently seem prefer the sound that systems that have speakers that do better with ss amps provide over the alternatives. Obviously I'm not alone.
