Kreall amp and tube pre

It's been awhile now and I need some input. Can I just plug and play a tube pre into a fpb 200 or later generation amp ? I think several yrs ago I saw a post that said you needed to do something to the amp. Am i right ? Is their latest generation of amps tube friendly ? The reason i'm asking is I have an all tube system but would like a SS amp for 2 channel home theater. Thanks.

I have tried the Aesthetix Calypso, Audio Research LS-16, SP-9 and REF One, Counterpoint SA-3 as well as a few others I can't remember. I am not using a tube pre at this time. I have an PS Audio PCA-2 that is great. And it is a balanced design which is important with the Krell. I don't know anything about the E.E. Minimax.

I would contact Krell before plugging the tube preamp up to the amp. They are very responsive. Better safe than sorry.

A great way to destroy your speakers. I would not do that.

I have spoken to Krell about the subject. The speakers won't be damaged, Krell has extensive protection on the outputs. The amp will go into protect if it senses DC. But it would be best to be cautious. Put a meter on the outputs of the preamp and check for DC. If you feel that something could go wrong, switch the resistors into the circuit.
