Ayre amplifier to Subwoofer connections

I am trying this question again with a more specific title to try to get responses . . .

I am intending to hook an Ayre, fully balanced amplifier to a subwoofer via the high level (speaker) inputs. Ayre has told me NOT to connect negative to black but to chassis ground. A balanced amplifier cannot be connected to anything with a common ground.

The subwoofer amplifier manufacterer (O-Audio) says the plate amplifier has no common ground by virtue of the fact that it only connects 2 prongs to the outlet.

I have also heard that other audiogoner's have connected Ayres to subs via the red and black speaker connections without a problem. How have you accomplished this?

Can anyone explain to me in more detail what is up with this technically and what connections I should be using.

Additionally, can you tell me the pros and cons of connecting the speaker leads to the sub from the speakers vs the amp. Does it have to do with length, noise, etc?

thanks to everyone in advance!

Drubin,

I have Ayre MXR's and a Rel Studio. I was instructed by Ayre to connect the red wire (positive) from the Rel to one amp's positive and the yellow wire(positive) from the Rel to the other amp's positive terinal. The black wire from the rel (negative) is to be connected to the center post that is used to tighten the Cardas terminals on one of the amps. This gives the black wire a connection to ground. Hope this helps.
