Tubegroover, your excellent post is probably the best explanation of why, despite having heard many solid-state and tube hybrid amps in my system "outperform" my Jadis JA80s in most respects, I still prefer to listen to my music (primarily classical, folk and jazz) through the Jadis amps. I very well might feel differently if I listened to rock more frequently; in that case, I think Garfish has the right idea. We all listen to music to be moved; for my music, tubes just seem to do the trick better.
