any krell power amplifier users use tube preamps?

Hi,

I was wondering if any krell full power balanced amplifier users 300c, 400cx, or 700cx owners use tube preamp? If so, I have a 400cx and am in process of buying on audiogon a high end BAT tube preamp. I am concerned that even though both Krell and BAT told me in emails that I sent them that the BAT will work fine with the krell amp, the krell 400cx manual states that prior to using a tube preamp one should have a krell dealer activate the coupling capacitors.

Well I bought the Krell on audiogon and so it would not be so easy to get a krell dealer to do this for me. Besides, the krell amp weighs a ton and can only imagine would require a krell dealer service person to come to my house!

Thoughts? Comments?

Michael

I used a tube pre Audio Research LS-16 with an FBP-300 and FPB-350M amps. The tube pre added a nice warmth to the Krell SS slam.

Be sure to address the jumpers before you connect a tube pre.

Some tubed pre's put out excessive D.C. and some don't. I've used a CJ ART2 into a Krell 600c without the coupling capacitors engaged. CJ told this degrades the sound.

I have a AR REF One MK 2 that I'm about to hook up with a recent purchase of Krell 350 mc's. Does anyone know if the Ref one puts out excessive DC. I'd like to leave the jumpers in if I don't have to remove them.

Thanks
