I used to sell Kimber Kable, and I had Kimber build custom PBJ "Y" cables for the store. If you like the Hero interconnect, perhaps Kimber would build you exactly what you need. They might even be able to build you a custom "Y" cable like a bi-wire interconnect eliminating the intermediate connectors. Just let them know what you are doing and the equipment that you are using. I am sure they can help out.
Another option would be to use a "T" adapter. This is basically gold plated male rca connector with a one straight and one right angle rca female connection. There are a number of cable manufactures that sell them.
