Making your own cables is a wise move.
Before I started making my own I was replacing junk cables every couple months.
I buy most my cable supplies from Pacific Radio Electronics (
http://www.pacrad.com).
Easy online ordering & fast shipment.
I use only Neutrik connectors for everything from RCA to XLR, but my primary connection is the 1/4" balanced.
For bulk cable I really like the Mogami (MAR2552) & Canare (2TS).
To make snakes I use the Mogami or Canare stuff as well.
It is a little bit of an investment upfront to get your supplies, but you will end up with far superior cable than anything you'll buy at Radio Shack or Guitar Center.
And, you can customize all your lengths, color code & if any cables go bad down the line, they are most always repairable.
Versus the disposable HOSA junk.
Make sure you practice good soldering technique & test all your cable for shorts (to be safe).
I find a mini-vise (you can buy from any hardware or electronics store), small scissors & a metal or plastic pointy type thing (to seperate shielding) helps a lot too.
In my case I use a metal dental scraper tool.
I am in the midst of making another batch of cables right now to wire up my console.
Only 28 more connections to go!!!
