I don't know about triode mode, but I heard from an incredibly knowledgeable former salesman (and CJ-lover) at Stereo Exchange (NY) that the 11a improves significantly if you upgrade the power cord. Of course, if you're not electrically handy, you'll have to have it done for you, but power cords are getting really good these days!
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.
