    So 3BSST is out? It is a dual mono design. Does that always precluded it from having a common ground? If it is dual mono does that mean you cannot strap the negatives?
    The 3SST is common ground already connected internally.

    Its the configuration of the amplifiers output stage that determines if it can have its negative terminals strapped together.Amplifiers that have bridged/ balanced output stages cannot be strapped because their negative terminals are not at ground potenial,they are active like the positive side,just opposite in phase. By connecting the negative terminals together you would be creating a direct short between two "live" outputs.This ofcourse could cause damage to the amp depending upon how forgiving it is of having its outputs shorted.

    Amplifiers, be they dual mono or otherwise that have their negative terminals at ground potential can have their negative terminals strapped together without risking damage. Many of these type have small value resistors that isolate the grounds of each channel from the other and safety ground.(So not quite common ground).Strapping the negative binding posts bypasses the resistors making the amp common ground.There will still be a connection to chassis safety ground.
