Agree with Tobias. You should also consider the Ayre AX-7E integrated - fully balanced w/ passive preamp stage and SET-like sonics. I swapped a NAD 352 for the Ayre a couple of years ago and it made all the difference for me.
Timbre, soundstage, and in particular, midbase resolution were dramatically improved.
