prz,
An interesting review, primarily your summary after the "BUT' part.
A couple of things offhand:
1) More power often equates to louder volumes which listeners perceive as 'better sounding'.
2) i would never equate more expensive to better sounding, that is quite presumptious, a 10k amp will not automatically sound better than a $500 amp
3) clock jitter was explained by Alan in this old post, you might want to take a read of
his explanation
4) How were you measuring the M80 down to 10Hz?
Seems that your TacT will take care of most of the issues you felt were issues with the M80s.
Enjoy the sound!
