Forgiving digital coax ?

I have used a Black Cat Veloce and Transparent Premium (previous version) between Sonos Connect and Parasound Zdac with very good results.

I have tried a few different cables and have been happiest with Kimber AGDL between my Connect and Rega DAC.

Empirical Audio sells a digital coax for $250 which is 4 ft in length. Even though I can't compare it to other high quality coax, I highly recommend auditioning it. 30 day return. It was a huge upgrade in my system. And Al did not discourage me from buying it.

I picked up a Creative Cable Green Hornet; seems to do the trick - very smooth. Really fleshes-out the lower midrange frequencies in my rig.
