Balanced Tube Preamps I Should Try

Bigkidz, if your still using the pass x pre, may I ask what your goals are by changing to tubes? Perhaps this is unnecessary, but please remember the somewhat low impedance load of the Pass amp when considering some tube pre's that may have higher ouput impedances, the SF is unuusally low for a tube pre in that regard.

Unsound,

I am looking to change the midrange to sound more alive. I have been using a pair of Talon Raven-C speakers and they seem to be too revealing with the Pass preamp, maybe too much of a good thing.

I've heard the Khorus Xs on a friends system with Pass X350. He has used Cary SLP98 and First Sound preamps to great success in that system.

I've been using a BAT VK-31SE with an X350 and it is a very good combo. I would highly recommend a BAT.
