the 5.1 system will be turned into a 3.1 system with a pair of 7Bs, a CC3B and the SW12 subwoofer. the pair of SR3Ms will be offered for sale, the pre/pro will be reprogrammed and the 5x225 power amplifier will enable bi-amping to either
the 7Bs or
the CC3B. more than half the system use has been for music listening only so the surrounds are not critical here.
i have it on quite good authority that it would be better to bi-amp the CC3B rather than the 7Bs. what say you on the best application of the 2x225 channels that will become available?
If half your system used is for music, you would be better bi-amping your 7B's in preference to the CC3. That said, the benefits of bi-amping are debatable at best. Bridging is a potential option, as Class A suggests, but as Class A points out it 'must' be a capable amp. The 7B's have a 4 ohm minimum impedance, and as bridging normally halves the impedance seen by each amp, your amp needs to be rated for a 2 ohm load. Bear in mind also that noise (as in THD) generated by an amp, increases as impedance is reduced.
Your best option may therefore still be running in single channel mode. Indeed if your five amp channels run off a shared power supply/transformer, you might find that you get more than 225W when less than five channels are running.
All that said, by personal recommendation would be to keep the SR3's and try and integrate them somewhere if you can - you will miss them when they are gone!
