I haven't heard the VH digital cable (love their Airsine though) but I use the Poiema!! 1.5m digital RCA. FWIW, I've compared dozens of digital cables in my main system and this is one that I kept; presently using it in in my studio system. It's detailed and neutral top-to-bottom.
The only RCA cables I've liked better so far are the HT Cyberlight, which has a slightly better sense of ease and flow, and a Concierto Violin with a more life-like presence.
With AES/EBU, the Stealth Sextet is by far the best I've heard, just does everything right, followed by the FIM Gold and Sonoran Lambda, which both come down a little on the smooth side compared to the Poiema.
I'd still like to hear the Cerious and the latest Marigo (had an earlier version) but I suppose at some point one has to just be satisfied, right?
If your system is nuetral to warm, I'd recommend trying the Poiema. Discounted, it's quite a good buy.
Good luck.
