You can buy 20' sets from Blue Jean Cables (Canare 4S11), Kimber (many of them), Audioquest and I'm sure there are others.
I have used all 3 and believe BJC are great for the price and I preferred them to Audioquest Rocket 44. If you would like to 'audition' Kimber and Audioquest (through Crutchfield) have satisfaction guaranteed return policies.
