When I talked to Krell about using the VTL 7.5 with my FPB650M monoblocks they said no problem at all. I did for awhile and the sound was great, and no problems. I used two other tubed preamps with these amps. Again no problems. Right now I am waiting for a custom made tubed preamp(Singlepower Audio) to go with the Krells. I have never changed over the Krells to "adapt" them for tube preamps. If your thinking about the 7.5 with your Krell, IMO they go very good together.
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.
