I have four RB-75's and a RC-7, with a Bryston 4B-ST 250 watt amp for the mains.
With the Bryston ST series there are the options of adding another two 4B's at 250 watts or a
8B bridged with 400 watts into one channel and 120 watts into two channels. Yes I would like
to put more watts into the mains but the 8B would be more cost effective.
