Which digital cable to use with a Benchmark DAC-1

Pjl2122, balanced model of Stereovox is a different cable. It costs around $350 if I'm not mistaking. The RCA version of Stereovox, the HDXV, is about $100. They are 2 different cables, cost and construction wise.

In my experience the KS2020 is a spectacularly good cable but too good for the Benchmark, the Zen MC2 is one of the worst I have heard (not even close to a 75ohm cable, so what do you expect), but for a cheapy that suits the rather thin and slightly strident sound of the Benchmark I reckon the single ended WideEye is a good match when terminated with Canare 75ohm plugs.

Redkiwi, Your point is well taken that if components are not at high enough performance level then a more forgiving IC is better tolerated.
It is not always a good idea to dumb down (as in school curriculum choices), but following your thought, it is better to enable pleasing synergy until one hears and can afford still better sounding components.
On the other hand, I think many of us have had the experience of unveiling more sound enjoyment from a component upon inserting "better" interconnects (regardless of price).
If what is unveiled proves less satisfactory then this may serve as a goad to start saving for the next purchase which will sooth the restless audiophile soul.

Indeed - in that context the KS2020 would be a good investment and a long-term keeper for when you upgrade the Benchmark.

There are some really good advice above. I have tried about every digital cable under the sun and ended up with the Illuminati D-60 Cable. I would also recommend the KS2020 as it is a fantastic cable.

The Apogee Wyde Eye and the Canare are great cables but can come across as grainy in the wrong setup. But then again they are ridiculously inexpensive. The Benchmark I auditioned was a bit thin and analytical to begin with. I would suggest going with a cable with more of a neutral to soft side of neutral character. The Kimber and Illuminati cables are not cheap but they are not $2500.00 either..

Good Luck..
