Could you please explain more clearly. The Bryston 7's are mono amps, by parallel, what do you mean? One for each channel in a 2-channel system? If you are just bi-wiring, it should not matter.
Audioquest Two ended Bi-Wire terminations
I brought a set of Redwood Cables I bought used from an authorized dealer who received them on a trade in. I’m they were Bi-wired on one end. I asked them to determinate the other end to bi-wire because I run my Bryston 7B’s in parallel. He said they can do it in house.
When I received them I tested them with an ohm meter and the two grounds show continuity. The dealer said the drain wires are connected to the ground on the amp side and they are tied together on the dbs side. This does not sound correct to me. Should the grounds be electrically bonded?
In some amps with two sets of speaker connections the grounds are common terminals inside the amp but on the Bryston your ground terminals are different in parallel mode.
