I owned a Krell KSA-250 for quite some time.
Eventually it needed service, sparks and smoke...yikes!
Anyway, I sent it to Krell and they charged about $400 (including shipping) to bring it back to spec.
So, probably if you find a used unit that has not recently seen service from Krell, expect to send it to Krell for updating anyway.
I did eventually sell the KSA 250 for about $2500 a couple of years back. So, current prices should be a little below that price range (if its been updated).
Great unit, puts out a lot of heat.
