755 or Rotel RMB-1095 or sunfire theater grand for B&W XT4

Hi,
My friend has a pair of B&W XT4, hes planning to setup a 5.1 but his reciever is a Rotel RSX-1056. It seems that its not enough for the XT series of B&W because of the low efficiency (85 db). What would be a good amp for the XT badboys?
outlaw 755 or Rotel RMB 1095 or sunfire theater grand?? all are 200 w per channel.or any other suggestons???
thanks

I would think that any one of those would be a fine choice. Since you mention the 755, I assume you are shopping the used market, right?

Re: Outlaw 755:

When I got my 7700 I was going yo sell the 755 and continue using Crown DC300A's.

I am so glad I sold the (old) Crowns and kept the 755. Even though I only run two or four channels with it I am delighted. It is quiet and clean.

The only reason I bought the other (7700) was that I needed it in another room and desired the 7 channels.

If you get a 755 you won't be sorry.

Thanks guys that was helpful. Probably go for a used 755, since budget is an issue at the moment and having already spent quite a bit on the XT4s, Rotel RSX-1056, REL sub and the nordost cables.....
