1. The entire system sounds excellent to me and better than I expected in the first-few hours.. Speakers were demo units, but I've never asked how many hours are on them.. Still have some treble tweaking to do, which is a bit of a continuing process for me with bad ears and using hearingaids.. The overall rez is astoundingly excellent; did I get used to the 20.7s' slightly lower rez?
2. I'm still using the Class D Audio GaN-FET** amps which still sound excellent (and will be called 'CDA Reds' hereafter).
3. The '5Cs' bass energy is about as great as that of the M745s, which means they have substantial bottom-octave bass at the '0' setting; they sound a bit 'thick' for me at the +3 setting.. I then reduced the SWs' level controls to 2 on their 10-scales, which is two numbers lower than I used with the 20.7s.
4. Also received the Bryston 7B3 monoamps, but one's power transformer is loose and sliding a bit about its center-anchor screw and doesn't work.
I thank Mark DeBiassi of Afton Mntn. Audio for his excellent service.
** hereafter 'CDA Reds'
I'm VERY happy!!!!!!!!!! On to resolving my Bryston problem.
