does an audiophile quality xlr 'splitter' exist?


Application is fully balanced Sim Audio Attraction HT processor to 5-ch fully balanced Theta Dreadnaught amp. Object is to add another identical Dreadnaught amp and vertically biamp each of the 5 speakers (Totem Mani-2's).

Short of adding a 2-ch preamp in the system that has 2 sets of outs (I have done so in the past, and works great, but only for front left and right channels), does any kind of a splitter exist that will take xlr female and split it into 2 xlr female outs (that obviously I would plug each male xlr end of the interconnect cable into) WITHOUT any sonic degradation?

I'm far from real knowledgable on this, but I'll throw in my 2 cents. Madrigal makes a balanced bridge kit required to bridge Levinson amps. I'm not sure it's what you need, or if it will work, but it may be worth looking into. Runs about $450 a kit, I think. You might want to check into it.
thanks everyone- good thoughts. I even got an e-mail from a dealer- 'Quest For Sound', indicating they have "CARVER PRO xlr y CONNECTORS" and to check out their site- hmmm.....
Sutts, that is the splitter (Carver Pro) that I am using with success. Charlie.
