Best amp match for Krell KSP-7B?

I mainly listen to the phono stage and do not own a cd player at the moment.
I just bought this and am using an old Bryston 4B as an amp.
I find it is kinda hard on the ears after awhile, and am looking into another amp to buy, suggestions?

a krell.....synergy and perfect for vinyl
Well, there are a ton of models, anyone have input on a model match that they have heard/own?

Ksa 100???
Depends on your price range. Buy the newest and best you can afford.
