Jeff Rowland amp owners: What's your pre-amp??


Hello everyone,
I'm looking into purchasing a pre-amp for my Rowland amp, and just wonder what pre-amp you are using for your rowland amps?

I use a Conrad Johnson 16LS Series 2 with a Jeff Rowland Model 10 amplifier. It's a great match of solid state and tubes.
I'm using an original Coherance One with 201's. I had to have a balanced cable made up with dual RCA's to XLR. I've had the premap for 11 years. My CDP or speakers will be replaced before my preamp.
I am using a EE Mini Max tube pre with my Rowland
Model 10 and it sounds fantastic! I would like to run balanced soon, but not sure what to get. Maybe
a Rowland pre?
Thanks a lot for all the replies. As for the input inpendance match, I believe my 302 amp is either 32k or 40k ohm. Does it mean that most of the modern preamps (tube or SS) should be able to match the 302??

Thanks
