"OK" so here is a bit of a follow up on this...
The "system" was:
The best of two B&K ST-202’s (as was the migration form a vertically bi-amp’d 1988 Vandersteen 2c’s), Vandersteen Quatros (CLOTH edition, as had been spliced into the system from 2C’s), a pair of MIT AVt-2’s, a REGA Apollo CD player (with MIT coax interconnect) feeding a now new Marantz 7702MKII, followed by Audioquest "Water" balanced interconnects to the amp....
As a very (extremely(?)) brief summary, I have been dabbling in this lower end of high-end audio since the late 80’s, and I am beyond anal in mechanics, technical execution, to the point L I S T E N I N G to the "music" over technical merits listening is at best RARE.
So here is the extremely short summary of a McCormack 0.5.modded by SMc-Audio "Gold(+) edition" amp: For the first time in 30+ years, this amp, in that system was "so good", that I actually L I S T E N E D to the "music", instead of critically "anal-i-zing" system performance. The amp was "sooo good" that it for the first time made it about listening to MUSIC instead of analytical "Sterophile" like "auditioning".
If you think you might ever like to actually, and just "listen to MUSIC", buy a freaking McCormmack DNA amp, get it modded... and "listen to MUSIC", it’s that simple, it’s that good. The amp lifted a 30 year curse of endless ANALytcal auditioning, and MADE *MUSIC* (I am certain, thanks to Vandersteen Quatros, etc.)
