Mr. Tanner, president of Bryston, warned me that the floating ground must not be grounded or else my balanced crossovers would become electronic junk. This has been confirmed by other companies such as Cardas which will make a floating negative conversion plug for RCAs to "Balanced" connector to plug into the ground of my Stratos Mono SEs when running w/o the Bryston 10B-LR Pro balanced crossovers. An active negative should never be plugged into a grounded negative. Call your front end manufacturer if there are any questions as many "balanced" systems are nothing more than a floating negative. Some companies such as Pass have pins to connect the ground to the negative on the outside only when using the RCA input.
