I think you should go for the 380S as it's pretty much a tube sounding solid state preamp. Have you ever read the review from Fi magazine on this 380S? I have a copy and can mail you the review free. The bass will be better, it will be quieter, no tubes to change, It's sound will always remain the same because there's no tubes to deteriorate, and it's midrange and highs are as smooth as butter. E-mail me if you want a copy of the review.
