I own a KSA 200S and it sounds good to me. My only complaint is that the amp does not take well to being shipped. It sounds good but not appreciably better than my Bryston 4BST. This may be due to the fact that my Ohm Walsh 300's while inefficient are not a difficult load to drive. If you live in a hot climate like I do then heat dissipation may be an issue.
Why Is Krell Not Considered Hifi?
No one seems to think that Krell sounds hifi, but just hifi price. They say it sounds hifi in that context that it doesn't sound real. I have to admit their products do have a metallic like cast to their tone, but aside from that I think that they are very smooth and detailed, far from the best in detail, like a CJ Premier preamp but they do make decent stuff. And just from looking at their products it makes you believe they sound as they look. Obviously its not true, but Krell makes decent stuff that has a good rep and is easy to resell (as long as its a current model, which is hard cuz they have so many new models) but its no way the sound of a Rotel or NAD that many people say.
