Pre-Amp for Parasound JC-1

Just ordered a pair of JC-1's and need a recommendation for a tube pre-amp . Particularly interested in performance differences between balanced and single ended operation.

These will be driving Wilson WP7 via Transparent Reference XL-SS. Source consists of AN CDT2 and Zanden 5000 Mk. III
Interconnects will also be Transparent Ref. XL-V.

If balanced operation is the way to go, it seriously limits the number of candidates. Thoughts/suggestions please.

Sue Kraft had intermittent trouble with her 30SE with the JC-1s shutting things down for a few seconds......The sensor opens the speaker relay so DC can't get through the amp to hurt the speakers......

Bob,
I've sent a note to BAT.

I'm not an EE so please bear with me. Is there an acceptable amount of DC (or DC offeset) from tube pre-amps which allow the JC-1's to operate without shutting down? Is this an inherent issue with all tube pre's?

Thanks for your help.

Perhaps a Sonic Frontiers Line 3.

Rcupka, you could do the big Lamm or the new BAT or you could get us to build you a preamp if you don't mind waiting a while.....Shoot me an email if this interests you......Regarding DC offset and tube units you really need to try it out at home as sometimes if the voltage bounces around it will cause the preamp to burp every now and then and shut down the amps momentarily.......

Hi Rcupka,
I'm having fantastic results with an Atma-Sphere MP-1. Truley a killer combo.
