Sorry for the slow replies. Audiogon does not seem to alert me of someone responded.
perhaps the picture will explain by what I mean in parallel of serial mode. But I can’t figure out how to attach a photo to a forum post here. If you scroll through on this link to the pic of the back of the amp you will see https://www.usaudiomart.com/details/649650757-bryston-7b-st-monoblock-power-amplifiers/images/2854881/
the Bryston 7B will allow you to use two wires (serial mode) or 4-wires (bi-wire on both ends) to connect each channel. It has to do with how the amps internals achieve the 600+ WPC. I know that obviously the drains (or what AQ calls the cathode) of the DBS are connected together but actually tying them to the ground signal conductor seems odd in a (let’s call it) double bi-wire configuration.
In a basic single ended bi-wire your signal grounds are obviously tied together.
I measured the continuity between the two signal ground lugs on the amp and they do appear to be connected together internally .
