Bel Canto Pre3 vs Jeff Rowland concerto

Has anyone listened to these two preamplifiers enough to garner an opinion about them? I have a really nice, heavily modified Air Tight ATC-3 that is simply too noisy with my new Emerald Physic 100db sensitive speakers - I have hiss coming out of the tweeters that is annoying. Thus, I am going to go to a solid state preamplifier which should be much quieter. I want to spend 2 grand or less and will definitely consider purchasing on the Audiogon used market.

And, if any other nice preamps come to mind in this price range, please suggest. I have always had tube pre-amps and either solid state or hypbrid amps. However, those Emerald Physic speakers are really THAT good to make me change my preamp out and use it in another application.
