This is kinda what I still don't really get either. I am sure using a Fryette PS or something similar would get really close but it won't be 100%. I'm still very intrigued by this too though. I have a Fargen amp on the way that you can switch out the EL 34's for KT66 /KT77/6550/6L6/5881/6V6 ECT without any biasing so with this capability in the Fargen the Synergy system REALLY has me intrigued. I listened to the Metropoulis demo against the real thing and it blew my socks off......such a cool concept.
