Krell FPB 600

I would like to know if Krell FPB 600 power amp is inverting or non-inverting amp? Has anyone used it to drive the bass units of Infinity Epsilon?

I like the unlimited power and smoother over all sound of the 600. I sold mine and purchased the 350 monos and liked the 600 better. So I returned the 350's to Krell and got a 600C which I later had upgraded to 700CX. I still have it.

Also did you find the heat factor similar to the KSA(I found it very hot for a 250w amp)?How did you find the mid/hi in comparison to the KSA and FPB(non C)? thanks again

The heat factor is about the same, it never bothered me. I found the 600 to be smoother overall in the treble and midrange with a larger soundstage but it's been a long time since I compared them.
