Don't buy any preamp, unless you want to spend about $10,000 or more. Go direct !!! I also have the Watt/Puppy 5.1, I also love classical music ;-). I'd always thought the puppy does not have enough bass and the high is a bit bright. Until I connect my Wadia transport and DAC combo directly to the power amp, and I tell you there is no going back. It transformed my system from a hifi room to a concert hall (Orange County Performing Art Center to be exact) I could feel the guy fingering on the Cello !!! I could feel the air vibrate !!! I used to have the Mark Levinson No. 26S, which consider by many as reference class even by today standard, that I'd just sold it here on Audiogon. Enough said ? Hope this help.
