Thank you Kuribo, could not have said it better myself!
To be honest gents, most amps leave me cold, regardless of underlying topology... Be it triod, push pull, OTL, SS class A, SS class A/B, analog class D, or digital. On occasion, there are a few amps in almost each class that I love for what they do for music. Some of these happen to be class D.
Eventually, I am pretty sure I will even hear an OTL that does not make my head shake in perplexity. Who knows, may be such ATMA amp already exists today, even though OTL is not on an accellerated evolutionary path per se... I am an optimist, and I know I have heard but a small minority of OTL amps in existence... I have not even had the opportunity of hearing every ATMA amp: until the target set is known to be filled with "NO" on each member, I am hopeful that a "YES" exists somewhere in the extant set.
As for square waves.... Love that clarinet sound, but I do not waste my time confusing paper and an individual graphs with music from a thousand different amps... I much prefer listening to music through my own ears one amp at a time... After all my ears have served my passion quite well since 1957 -- the time I was first mesmerized by music coming from LPs through my Dad's Grundig.
