I made my own using, well, Monster Cable...
The cable itself is pretty decent quality (I used THX certified). I use Neutrik phono jacks and the 'fake' Nakamichi RCA's...
Haven't listened to it yet though, but home made is certainly the way to go.
I used chassis RCA's to run from the phono jacks, then 4 pairs of RCA's to run off them to the amps. I think it was easier to do this than run pairs off a single phono jack.
I think I have 4 or 5 Neutrik 90 degree 1/8" jacks still...(I decided to go with the straight jacks instead)
