"DAC MAGIC "Coax digital cable recommendation

Used, for under a hundred dollars you should be able to find a Harmonic Technology Cyberlink Platinum. Excellent digital cable.

I third the Blue Jean cables. Properly impedance matched, well shielded and quality build.
The cable used for these is designed for data transmission and at rates that well exceed current audio data requirements. I like to keep mine at least 1.5M long to prevent early reflection from entering the data path. Some will say that it is unnecessary at the data bandwith of audio but it can't really hurt. I'm from the computer data transmission world and it's mandatoty there so following tradition just gives me the warm and fuzzy.

1st of all thanks to everyone and i really do appreciate it a lot for your cable recommendation.
Btw,i would like to wait for my newly acquired s/s mcintosh c-15 preamp to replace old nikko pre and hear the sound difference.My ic's are all Harmonic Technology...but now reading more reviews on Blue Jeans cables.

Which one of these model are most use from " Blue Jeans "?
