Feed back on ARC Ref II Tube Pre with Krell Amps

Rwwear is correct with the early BAT preamps leaking DC. At one time I had twelve SS amps in my home to audition and the BAT blew a few of them that were sensitive to DC output.

I have heard the Krell amps mated with the Hovland tube preamp at many dealers including Sound by Singer in NYC so you may want to give them a call or CSA Audio in Montclair, New Jersey. Both should be able to offer good advice. At Stereo411.com, you can find the phone numbers

Happy Listening.

I once used a REF1 with my Krell 600c with no problems and without the DC block. I wasn't very impressed with the sound of the original REF1 but that was a long time ago. I have never had a problem using my amp with a tube pre but would be careful if not adding the DC blocking capactors. Early BAT preamps were known to leak DC.
