Krell FPB400cx coupling capacitors question


Does anyone out there have instructions for engaging the coupling capacitors on Krell amps? I have a Krell FPB400cx, ARC ref 2 MKII and First Sound Ultimate tubes pre-amps. Is it ok to run between those? Please advise. Thanks guys.

many tube pre amps will pass DC your best bet is to call Krell to get the facts.
I have ARC Ref 3. I have once called Krell and they told me that it is OK to run ARC gear without the caps.
