If you do not want to add color (some people love it) to your amp, try Bryston 60. It is an integrated amp, but it has output from Preamp section. I have used it with Cary SLA-30 amp and I loved it. You can find one in Ebay at $ 600-1200, if you are lucky. This integrated amp itself is a wonderful amp, if 60W is enough for your system.
Best preamp for $1000 or less with remote
I'm looking for the best preamp in the price range of $1000 or less to go with my Emotiva XPA-2 power amp; the preamp must have a remote for volume control. Any suggestions would be greatly appreciated. I'm willing to go more than $1000 on a preamp that might be worth the extra money. Thanks, Bob
