Best digital cable $300 or under new or used?

Look for a used Stealth Varidig - the original not the new one which is well beyond the $300 mark... True 75ohm and awesome

You may wish to add Audioquest Eagle Eye (75ohm) for digi-coax and AQ Raven for AES/EBU to your list. They both do a tremendous job in all the areas you are looking for.

When I added Eagle Eye for DD 5.1 and DTS from my transport
to surround pre/proc, I was very surprised at how much of a
difference it made in my HT.

Raven from my transport to my DAC was equally stunning.

You can often find these cables in shorter lengths used
on A-gon at your price point of about $300

Cogen Hall EM digital cable if you can find one. Also, K-works makes a very nice cable but they are not easy to find on the used market and are about $500 new if my memory serves me correctly.

I only have experience with the Stereovox vx2 versus the cheap $20 cable offered by Benchmark Media when I purchased their DAC. I am still breaking in a 1.5M Stereovox, but the difference was immediate and not subtle. Considerably more air around the music voices and individual players, greater 3-dimentionality. Looking forward to hearing this cable with 50-100 hours on it.
