Monoblock Suggestion?

If you haven't already chosen amps, consider using a pair of tubed stereo amps in mono. With a tubed amp, one merely runs the 2 channels in parallel and ends up with the combined power into half the indicated output impedance. For instance, an inexpensive c-j MV75, rated at 75 WPC into 4, 8, or 16 ohms, becomes a monoamp capable of 150 watts into 2 or 4 or 8 ohms. There are lots of medium-power, stereo, tubed amps (such as the c-j Premier Eleven) that are excellent candidates.

I'm currently running a new-to-me c-j Premier Eleven-A (70WPC) in stereo driving my quite-efficient (94dBA) L/R speakers and just bought an inexpensive c-j MV75A that I'll use as a 150-watt monoamp to drive my low-efficiency (85dBA) Aerial CC3B centerchannel speaker.

Good luck.

Thanks Guys

Audioengr,
I am very interested in your advertised Turbomods.
Do you have any customer feed-back from people who have had their JC-1's modded with the Empirical Audio Turbomod?
Thanks Steve.

I have a pair of Enterprises driving my Thiel CS3.6's, and I really like them with my Thiels. I definitely like the sound of Theta Digital's amps. I find them to have great width and depth to the soundstage, great instrument separation, and a very musical presentation. Low end is strong, but accurate, and while not as overly thick as some amps, I find them to be true and accurate.

The Enterprises would be my first choice. Pass Labs would be my second.
