tube pre amp and Krell FPB 600

Krell in its reference manual says : Tube pre amplifiers , by design, are capacitively coupled. For this reason, the benefit of a direct coupled amplifier can not be realized when used with a tube preamplifier. Additionally , many tube preamplifiers output a great deal of DC. This DC may exceed the servo of a FPB amplifier. Excessive DC level in a signal can damage amplifier , speakers , or both.
Can I use Air tight ATC 2 pre amp with Krell FPB 600 ?
Please advise.
Thanks

I don't know about the pre-"cx" models, but I have a FPB 300cx and there is an internal adjustment that needs to be made to accommodate tube pres. I have had this done and my amp works just fine with my Wyetech Opal tube pre. Is this discussed in the Instruction Manual for the FPB 600?
