Recommendations for a "mid-fi" digital coax cable?


I am looking for a recommendation for a digital coax cable that costs no more than about $150 to connect a Wadia iTransport to a North Star M192 DAC. Does anyone have any good suggestions? I am looking for something that is musical, detailed, but (most importantly) non-fatiguing.

Also, is there any truth to the idea that a longer digital cable (1.5m) sounds better than a shorter length digital cable?

Thanks

The Apogee Wyde Eye would come in well under your budget and is detailed yet also smoother, more liquid and full sounding versus some of the more detailed and analytical digital interconnects I've had in my system.

Stereovox XV2, which you can purchase online at gcaudio.com. Chris Somovigo's successor to the Illuminati cable. Engineered correctly and well made, works with both RCA and BNC connections. Go for 1.5M just to be safe.
The plain ol' copper Signal Cable digital coax is suprisingly good! For something like $30 and a 30 day home trial, you can't go wrong.
