The HR has too much resolution for its own good, resulting in no sense of air whatsoever. Too much of a good thing. The KRC 3, which isn't all that great a preamp, does air and space better than the HR. The KPS 20iL is just a tad dry through the midrange, but it one very impressive piece of business otherwise. I was very impressed by it. The better option, I'd say.
Krell KPS-20i/L or 20i w/KRC-HR
Has anyone heard the KPS-20i/L into a Krell amp (300S). I would think that this is the best way to go, but Krell says the KRC-HR is a better pre amp. Still wouldn't it be better to not have a pre amp with a one source system?
