Preamp recommendation please..

Hello,

I'm looking to buy a 2nd hand preamp, to match my Krell Evo 302e amp.
Speakers are Vienna Acoustics Beethoven Concert Grand.
I like setups based on tube preamps and SS amps, but this is not a must.
Most important for me: Transparency, Musicality & Drive. Smooth sound, not thin or clinical.
Fully balanced models are preferred.
Budget is around $3k.
Any help and information would be greatly appreciated.

Tnx.
