OK folks, I thought I would add to Serge's wonderful review!
If you didn't think I was crazy before, I will now remove all doubt.
I use 2 RGPC 1200's on each & every one of my Amps, one in series & one in parallel.
As for every other source & processor I go thru the following units in this order:
1) McIntosh MPC1500
2) PS Audio Powerpack 1500
3) PS Audio Power Plant Premier
The PS Audio Powerpack 1500 is a brand new device from PS Audio, it is in essence an audiophile grade UPS.
This configuration has yielded the absolute best possible audio reproduction from my System.
Yes, I have tried every other conceivable combination. This is my "Magic" recipe.
