Tube Pre suggestions for Mac Amp


I have a McIntosh power amplifier that I am running CD directly into. I wanted to know if any of you Gon'ers have had any experience using a tubed pre on a Mac solid state amp and what you found to be a synergistic match.

I'm using a CJ premier 14 with Mullard tubes - great match. Mac amps have a low input impedence and some of the newer CJ amps have a high output impedence, the premier 14 is less than 250 ohms, similar to Mac preamps. I don't know if it really matters, I'm not technical enough, perhaps listening is the best judge when possible, but just an FYI.
I second the c-2200 it works relly well with mac solid state at least with my 7300. recently tried a rouge magnun 99, that is my friends, and it wasn't as nice a match. also agree that its better to have a pre in the chain with my mac just sounds much better
MC602 with a c2200 is my best combination to date. Any speaker seems to perform to its fullest especially the Magnepan 3.6R it makes one want to step up to the 20.1R.
Hey, I like the VTL amps you had listed, can you list them again? steveinminneapolismn@hotmail.com or call me at 612 227 2787, thanks!
