B&W 801 Matrix III...which amp to use??

Thanks guys! Keep them coming. I am also using biwire
AZ Satori's, if anyone thinks there may be a better
match cable wise please include your opinions.
I like what lies beneath in these speakers, I just need
to have more bass control & volume for starters. Imaging,
depth, & soundstage are almost there.

Does anyone have any thoughts on a Bryston 4B ST
or a digital amp?? Or say one of the bigger Parasounds,
Rotels... Marsh...Adcom... etc..
