Solid State Preamp for Nuforce 9SEV2


Is anyone driving their Nuforce 9SEV2 with a solid state preamp? Any suggestions?

I am presently driving mine with a BAT VK 31SE and was wondering what may be my next move.

Thanks in advance for the feedback!

I don't have the SE's-just the regular V2's, but the Oritek pre-dac is one fine preamp(and dac too, BTW).
If you get a chance, give the Promitheus Reference or Signature a try. This TVC does not add any signature of it's own. I am pretty happy with mine.
