Why don't you just get the Premier 12 monoblocks in triode mode? Then you'll have ~70 watt triode power and a better match with the rest of your system.
Conrad Johnson Premier 11a--Triode?
Has anyone listened to CJ's Prem. 11a in both the standard (70w; 6550) and triode (35w; EL34) configurations? If so, any thoughts? The balance of my system will be Wadia's 850 and JM Lab's Mezzo Utopia's. All connected with Transparent Reference. I'm probably going to run my Wadia right into the Amp, but if I do go with a pre-amp I'm thinking of CJ's Prem 14 or 16ls.
