I don't mean to throw a sudden curve ball into the mix, but having already owned the Rogue Cronus, Prima Luna Prologue 1 and 2, and the Jolida JD-302 (along with a few of their hybrids), I'd highly encourage you to take a glance at the Vista Audio i34. It's not much to look at, but it's performance more than makes up for it to my ears. While the aforementioned pieces are all great in their own regards, I just find the Vista Audio i34 to be more of a well rounded performer, with no real gaping holes in its presentation to speak of. It's linear in all the ways a good tube amp should be, is as musical as one would expect from glowing glass, and moreover, it's performance is pretty darned consistent across a WIDE array of loudspeakers.
Dunno, just thought I'd mention it!
