Thanks for the leads, Steven, and I did find a C30/P30 for sale together, but of course the P30 was dead. Besides, I have a good preamp, thank you. I am in no hurry - listening to the P30 right now, and it sounds good. Yes, it has a voltage selector - given that and monoblock capability, what more could you ask for besides the name "Krell" on the faceplate? I may be a snob, but my ears are aren't.
