plinius sa-250

I am purchasing this amp and would like some input. This will be the 2 ch. amp in my h.t. system. As of now I have the Krell KAV-500, which will handle the center and rears until i upgrade to a more powerful 3 ch. amp. My speakers right now are Revel performa M-20s, B&W center and rears. Eventually the M-20s will go in the rear and F-30s will take the l&r chs. and the C-30 will be my center. The sub I'm running now is the Velodyne FSX-12 but will be replaced by the Revel B-15. The room I have the system in is 22'x13'x9' and I have wall to wall carpeting. I have the l&r speakers connected with Transparent Super XL bi-wire cables and the rears with Transparent The Wave 100s. I will have the SA-250 connected with Transparent Ultra XL balanced cables. The rest of the system is hooked up with other Transparent, Monster and Audioquest cables. I would like to hear any comments on the SA-250 amp and the Bryston 6bst, which I am considering for the 3 ch. amp. I hope this is enough detail to allow my question to be posted and have well informed responses in return.
