Digital cable recommendation

The Wireworld Gold mentioned is a good choice but the best choice by a huge margin in your budget is a used Acoustic Zen mc2....bar none.
If you want a more musical digital cable than this....plan on spending 4-5 times as much IMHO.

Seems the i2digital is the cable to beat. A friend of mine sold his 2,000 Kharma digital interconnect and replaced it with the i2digital...

Cardas Digital lightning L15. Warm and smooth, like a baby's butt.

Psychicanimal, no Ridge Street Audio Design digital? Do you still favor their interconnects?

I've been using the Silver Serpent digital coax from BetterCables.com for more than a year, and have been very pleased with it. The Silver Serpent is a true 75-ohm cable (VERY important) and has excellent build quality, and it's hard to beat for $80. If you are not familiar with BetterCables.com, I urge you to take a look at their product line. Here's the link to their Web site:
