The color of the outer jackety for Phoenix Gold TI-122SB (or "Musical Reference") cable is clear, the jacket is very thick, it doesn't show in the picture posted by the etailers but the diameter of this cable is about 20 - 25% bigger than the coaxial cable for satellite dish.
I have this cable for about a month now, it beats the RCA brand I had before, it produces more details and clearer sound. It's a good quality, inexpensive cable, the only draw back is the length one has to buy.
I don't have experience with the other two Phoenix Gold cables but specualte their performance would be similar to this one.
