If you can solder, this is an excellent interconnect for audio, S/PDIF digital and composite video:

The choice of using RG-59 coax was one which took into account all of the above criteria, and it performs extremely well at frequencies up to those of composite video. The propogration time of the particular RG-59 I use is something like 78%. The characteristic impedance is 75 ohms which matches digital audio S/PDIF pretty closely, and is compatable with the output impedance of any likely audio components. The only thing I would look out for is to get cable with good shielding. I have found the density of the braid varies greatly from different sources. Go with a cable that has a braid comparable to the one in the photos in my DIY project.
