So I have a bit of a dilemma (one might even say a trilemma), where I am looking to upgrade my Carver AV-705x (125w/ch). At present I have three options - Sherbourn 5/1500A, Sunfire Cinema Grand or a set of TX4430 (3 ch) and EX4420 (2 ch) amps. They are all 200w/ch. All have great reviews with the former being cheaper, less known and not THX, and the latter two being roughly in the same price range. I have a set of 5 Sunfire CRM-2, so one consideration I've heard is that it'd be better to pair Sunfire with Sunfire, both using Bob Carver's Sonic Holography. Nonetheless, the questions remain - which one of these to get. Any input is welcome.

PS I really can't borrow either one to audition, except that the Sherbourn did sound better than my Carver.

Thx!
