I've purchased most of my individual cables over the last several years from Hot Wired cables.

And I've purchaed most of my snakes and patchbay wiring from Redco.

I recommend them both highly and wouldn't hesitate to order anything from either one.
I do have some nice cables left over after my upgrade if the original poster of this thread is interested. They are ProCo Ameriquad brand cables. Proco's quad cable with black Neutrik connectors and gold contacts. I have six 10 foot and one 20 foot. They are in like new condition. They sell for $20 at American Musical Supply but I will sell for $10 each and will throw in free ground shipping in the 48 US states if you buy them all.
The ONLY reason I replaced these is because I wanted to try to get to a point where all the cable in my studio is the same brand and model if possible.
I have other cables I replaced and I'll put a big list in the forsale section here today or tomorrow.
Best of luck!
