Integrated amp up grade?

Here's a little history. I have been a SS guy my entire life. My last being a Yba Passion Integre. Loved it, but I decided (with some strong suggestions from other audiophools) to move to a SET integrated after purchasing my Zu Definitions. This has been a marriage made in heaven. I never realized, never having speakers before that were sensitive enough to be driven by tubes, how wonderous the SET sound is. I was thinking Mastersounds 845 Compact. Cannot be found anywhere right now. They (being in Italy) don't have a US dealership. Suggestions? First hand experiences a plus or excellent second hand ones appreciated. thanks in :)
