My y-adapters from Synergistic Research arrived earlier than expected so I set up my 2nd amp (now with 200+ hrs of burn-in disc signal) next to my first, flipped the switches, rewired the speaker cables as per instructions, and voila, the monoblocks live! In a word, stunning!!
I have been knocked out by the sound of the stereo Musician III Mark 2, but I was not prepared for the increase in clarity, dynamics, resolution, soundstage depth and just an overall ease to the presentation. It's quite a combo when you use dynamics and ease in the same sentence. I told a buddy that the analogy is a pickup basketball game where one team is basically standing around in their dress shoes, suits and ties, yet still beating a group of youngsters 40-0. Total control, not a drop of sweat.
I did uncover an interesting anomaly. although I read on the Spectron site that the conventional wisdom was to use each amp's right channel as the red/positive side, I paid little attention, thinking it was a coin flip decision. Hwoever, there was a definite phase issue when set up the other way (left channel of each amp positive and normal phase). Why? Simon reminded me that it had to do with AC polarity, and that the majority of installations would have AC polarity set up correctly for right/pos, left/neg and not the other way around. And he was right (pun not intended).
The Spectron monoblocks are truly state of the art IMO. Combined with the rest of my system, I now have a Hubbell telescope that is beaming back warm rich colors of the universe, and I'm able now to tweak the rest of the system to discover subtle cosmic nuances heretofore unknown. It's very very cool...and musical as heck.
