Hi, I wanted to touch on something JackD stated. He said he heard that the Musical Designs SP2B worked well with ss amps. I haven't heard the Odyssey, but did a head-to-head comparison between the Musical Design and Rogue Audio 66 preamps. While the MD was very clean, it was very dry and etched sounding compared to the stock Rogue (even after I did some tube rolling with the MD). In fact, I wanted to like the MD better, but ended up purchasing the Rogue. I have now had it upgraded to the magnum version, and with some tube rolling, it is not even a close contest -- the Rogue stomps all other preamps in its price range (and I've compared it to quite a few -- Conrad Johnson PV10AL, Golden Tube SEP1SE, Musical Design, Cary -- don't remember the model -- and VTL 2.5, just to name a few). Good luck and let us know what you decide.
