Thanks for the input, Larry W., and Rmml. Is it a coincidence that both replies are using the Sonic Frontiers pre amps or is there a specific synergy with the SF and Krells that I'm not aware of. Thanks again.
Krell amps with tubed pre-amps
Suggestions and/or experiances with SS/TUBED combination. I own an FPB 200 and looking for tubed pre amp to match. ( $2000.00 used ). I know there is a minor adjustment needed inside all Krell amps if one is to match it with tubed gear. I'm not sure what specs the Krells like seeing in tubed pre amps. ie, impedence, output etc. Thanks!
