Which Pre-amp. match with Krell KSA 200S Pow. Amp?

A cary SLP 2002 or a SLP 05. Krells sound better balanced and with a good balanced tube pre-amp like the two I mentioned you cannot go wrong. The Cary tube pre-amps will warm things up a little on the KSA 200s which can have a bit of a bright sound. Most friends of mine that own Krell amps from that era end up with these pre-amps. Still be sure to get the correct tubes that will compliment your system.

KSP-7B or KRC. I have never heard Krell amps sound brite. Match your amp and preamp and you will eliminate a lot of problems.

I like SF with my Krells. CJ is also a good match ... heard it many times except CJ is not balance. I'm not a fan of Krell preamps but one of my buddies use KRC with his KSA200s.

I never found Krell sounding bright if PROPER cables are use. From my experience, MIT worked best for my taste.

This pre-amp will work well.

Krells sound pretty good with almost anything. They are just great amp!!

I would suggest the Cary's, Rogue's, or Shindo, or Manley's.
