Im currently using a 9BSST with OB1's, DB1+, TB2+C.
I have been looking at other amps but nothing so far has really made me want to leave Bryston.
I don't think Im getting the best out of the OB1's (for music) with the 9BSST so Im thinking of getting a 4BSST for 2ch duties. Would this give any real sonic benefits over the 9BSST? If so, what are the benefits apart from more power?
As for the other 3ch, I have been offered 3x120 powerpacs at a good price, but these are the ST version. Will this cause a noticeable sonic difference with the 4BSST?
