Have to agree with Sdcampbell on this one. Having owned various Bryston gear over the last 12 years or so I can that the ST series is their best bar far. If you wanted a good strong amp for a home theater application where the desire is to reproduce action packed scenes with little regard to quality of sound then I think the a NRB version would do you fine. If you are at all interested in the quality of the sonics then the ST amp is the way to go.
