Digital coaxial audio cable suggestions.

One meter is a length that will often not be optimal. See this paper. While the paper recommends 1.5 meters, IMO a very short length (e.g., 6 inches or so, or perhaps as much as 12 inches) may also be a good choice, if that is physically practicable.

There will be exceptions to these guidelines, of course, depending on various technical characteristics of the components that are being connected.

Listen to Al. Go with 1.5 meter.

As for suggestions, one good choice is DH Labs Silver Sonic D-75. It's well shielded, reasonably flexible, and sounds good. And at $90 for 1.5m, it's less than half your budget.

I agree on the 1.5M length being optimum in most cases.
