What can you tell me about First Sound pre-amps?

ARTG, my admittedly aging system is as follows:
EAD T1000 transport..
EAD D7000 Mk.3 DSP.
Audio Research LS2B linestage.
Jeff Rowland 7M amps.
MagnePan 3A speakers.
C-Core AT&T glass wire between transport and DAC.
Audioquest Quartz RCA interconnects to linestage.
Gutwire Synchrony XLR interconnects to amps.
Cardas Golden Ref spkr wire to speakers.
Cardas Golden Ref PC on 7M amps.
Stock PC on other components.

that's a fine system, Guido - I only asked because you frequent the First Sound discussions, and seem pretty familiar with its virtues. Maybe you should pick one up!!

Yeah, that LS2B is choking your system!

I can tell the LS2B is choacking the system from the slight sickly bluish tinge that the golden faceplate of the amps assume when I crank the system up.
I think the 7Ms are going anoxic on me.
