Tubed preamp with Krell KSA 150 amp?


I am planning on selling my Audio Research LS3b (ss) pre and trying a tubed pre, possibly a BAT, Aesthetix,modwright, etc.
Any input would be appreciated...I have heard/read that some of the Krell amps need to be tweaked (dc?) to be compatible with a tubed pre.
Thanks,

Sgr,
a bit out of my price range...but I'm sure that it would. Did you have any issues mating tubes with your krell 250's?
Thanks for the above input all...
I was hoping that someone has some direct experience with using tubes with the Krell, as I wrote in my previous post, I understand that there might be a compatibility issue.
"Knghifi
All I've used with my Krell KSA100s, FPB300 and FPB600 are tube preamps and never had any problems. The only issue I encountered is some tube preamp output impedance is too high and as a result, sound is dull and lacking LF/HF."

what # would that be? I am looking at a modwright now (swl 9.ose signature) and I believe that the output is at 600 ohms...
thanks,
paul
