Forget all of the above and look at the Maple tree tube preamp for under $700. Comes in a kit also if you want to save a few bucks. I recently hear one and it was musical as all get out. Fast, clean, slightly tube warmish but real musical. COmes witha 10 day trial offer too. If I wa starting over, I'd put in my system and laugh all the way to the bank. Paired very nicely with the Channel Island D-200 digital mono amps.
Happy Listening.
