SS preamp to give wormth & bloom to Krell KSA amp

Pass Aleph

Second the Rowland Synergy IIi, or a Classe CP-60 if the JRDG is priced too high. You didn't mention a price range.

I have had a few SS pre amps and tube pre amps over the last 5 years such as Sima P5, Krell KRC-3, Pass Alpha P, Bryston SP1, Sonic Frontiers Line 2 & 3 and by far the best match and compliment to my Krell FPB amp(s) has been the Ayre K1. They compliment each other and the result is excellent. If I were you I would look at an Ayre Pre.

would look at the jeff rowland gear and the latest offering from muse ( signature III...not as warm as the rowland but close).

good luck,

mike

I'd recommend a Pass Labs X2.5 or a Pass Labs X-1 preamp.
