Bryston 4BSST bridged = 7BSST monoblock?

Is the 4BSST in bridged mode electrically identical (signal path circuit topology) to the 7BSST? I noticed the published specs are virtually identical.

I confirmed this with a Bryston tech when I was comparing both amps for a subwoofer application. The wattage might be close, but a bridged 4B ST won't be able to handle the very low impedance loads the 7B ST is designed for. Plus, the 7B ST should have much more current.
