Hi Jim,
Glad to hear that you're enjoying your new kit.
Wanted to head over to the show as well, but my schedule has been a bit busy of late. Having heard most of the kit at the show in one form or another, there is, no doubt, certainly some amazing equipment to behold. Knowing this, IMO, I should think your setup would be tough to beat even by the likes of some of that uber kit.
Like you, I too have recently come around to the FRD / SET scene, having purchased Zu Tones and Micropure Kotaros (w/ 4" drivers) within the last year. The Kotaros are paired with Triode Corp 300B monos (20W paralleled SETs) and a REL sub and it's pure magic. Aside from the quickness, coherence, and intimacy; to me, the most startling thing is the sheer amount of sound that comes out of such a relatively small driver - hard to believe until you hear it for yourself.
Cheers,
Garry
