A friend of mine has the new J2 amp which he uses on a very high efficiency horn based system (105 db/w) and on some fairly low efficiency mini monitors. I believe he was using the Levinson No. 32 preamp in order to go fully balanced all the way from his SACD source to the amp. I thought the sound was quite good -- grain free, clear, and reasonably free of the artificial edge to the attack of the note and unnatural decay of notes that often characterizes solid state sound.
However, it would not be an alternative to most solid state amps because it is quite low in output (something like 20 watts, if I recall correctly).
