Which digital cable to use with a Benchmark DAC-1

Yes, my experience too is that the digital cable makes a difference as large as with the other interconnects. I use a LAT International DI-30 Signature, in a balanced version, which is recommended for use with the Benchmark in order to get the best sound. In my system LAT has outshone much more expensive cables. I would try several cables before settling on one.

HI UTOPIA,
I AGREE WITH TEAJAY & RJA. THE ACOUSTIC ZEN IS A VERY GOOD (& ENJOYABLE) DIGITAL CABLE. IT IS BETTER THAN THE STEREOVOX.
ALSO, YOU MIGHT WANT TO GO INSIDE YOUR DAC-1 AND JUMPER OUT THE DIGITAL CABLE SELECT SWITCH. IT IS AN AUDIBLE (& CHEAP) IMPROVEMENT.

HDXV is a good cable for the money, but I just don't think it is a good match for Benchmark. It is not a very smooth sounding cable and DAC1 is not a smooth sounding dac. I would recommend Virtual Dynamics NiteII. You can try different cables from Cable Company and AZ MC=2 is certainly one that should be added to your list. Since you are talking about HDXV, I suppose your budget is under the cost of NiteII. But once you hear this cable, I doubt you'll want to use anything else. In a long run, I think NiteII is worth every penny. I evaluated NiteII with the Bel Canto DAC2 in my system and it beat AZ Silver Bytes, Stereovox HDXV, WireWorld SuperNova 5+. I never thought there could be that much of an improvement caused just by swapping a digital cable, but that was exactly the case.

Forget the rest - Go for the Kimber Select KS2020.
If you want to know let your music covered with vanilla creaminess, go for the Kimber Select. Period.

The Kimber D60 is the cable I would recommend. It will compliment the clean, clear delineation of the Benchmark without creating any brightness. I strongly disagree that the inexpensive Canare cable would be a way to save money. I found it to be hard, grainy, forward, aggressive and spitty in the treble.
