Which Krell to hunt down on the used market?

I tried the MD300's in my system for a while and they sound very good. They are warmer sounding than the newer FPB's - a little less 'neutral'.
I was also concerned about the cost of a future re-cap with a near 20 yr old amp. These things generate a lot of heat, even when they are standing idle with power on. Assuming that the previous owner(s) let the amps stay powered-up mostly, that's a lot of heat for a lot of years, and enough reason to justify concern/caution.

I've owned the FPB200 and it was a very good amp but didn't quite have the grunt that I needed for a pair of Magnepans. I've briefly heard the newer FPB700 and that sounded very good, very neutral. Incidentally, neutrality might be the holy grail for many audiphiles, but it doesn't always work in the real world.
Be sure to listen before you buy, if you are not familiar with Krell amps.

Concerning neutrality, it's an over-used descriptive and generally intended as a positive attribute of a component or system. Yet many people prefer the musicality of tubes, which in most cases are not considered particularly neutral. I've heard people talk about Krell amps being neutral, like it's a really good thing. Yes it's neutral, but is it musical?. I found the less neutral MD series more musical than the more neutral FPB series. The added warmth through the midrange effected a tonal balance that suited my ears.
There really isn't a lot to think about, so don't strain yourself on my behalf. You want neutral?... go knock yourself out.
