Thiel 7.2: amps suggestions please


I'm a 7.2 owner who looking for a really good amp to match with my speakers. My actual ss monoblocks rated at 250 watts(doubling on 4, 2,1 ohm) Class A probably are not enough: my feeling is that 7.2's eats power like no other speaker except Apogees ! Welcome to any suggestion, specially from 7.2 owners. Thanks.

Rob, thank you very much. I'm in contact with Irish, yes, and he's just replyed to me after his tour at Thiel factory, he decided for the Pass X600 too. Cheers, Luca.
P.S.: you have a great gear, enjoy !
Rob, your "virtual system" is the reason why 5 months ago I started to investigate about Pass amps, thanks.
I received suggestions also from Thiel's factory: they currently use Krells for the 7.2 but now I'm waiting for my pair of Pass X600.
I'll repost here after audition with the amps. Again many thanks for all suggestions and comments Audiogoners, and thanks again to Shari at Thiel, great support !
You probably can't go wrong with the X600's! Pass was definitely on my short list, but unfortunately, I was not able to audition them.
