Balanced XLR biamping

[m10]

Hopefully a simple question --

Is anyone bi-amping with balanced XLR interconnects here? If so, what do you use to make two go into one at the pre-amp end?

Friend of mine had cables specially terminated by Chord Company - is this (or something like it) the best way to go? Or is there a cheaper and just-as-effective way forward?

Thanks.

I have several unbalanced pre amps with 2 outs. These are just daisy-chained and are not separate feeds. You could make some dual xlr sockets for L & R outs. I can't see why that would not work. If it didn't you've only wasted a few quid.

Something like this might do, although the male/female orientation may not match.
