DC issues using a Krell KSA 150 w/ tubed preamp?

I could be mistaken, but I thought that Krell discouraged tube pres with their amps, but in a nod to those that insisted, there was an internal switch on some of their amps to help protect them from tube DC.

Unsound,
That is what I thought that I read somewhere...I'll have to call Krell.
someone just listed here a BAT 50se that he was running with Krell KSA 200s and says that they sounded great together, I'm going to follow up with him to see if he had to do anything internally.
I'm looking at a modwright 9.0se signature...any thoughts?

I have a Krell 100-S that I run with an Audio Horizon tube preamp, sounds wonderful to me.

I had a pair of Krell 300S with a Audio Research Tube Pre Amp - LS5 MKII and it sounded great - no problems.

There is no such thing as 'tube DC'. No preamp, tube or solid state, will make DC at its output if it is working right.

IOW, the idea that tube preamps have DC at their output is a myth.
