I have one 1/2M SYNERGISTIC RESEARCH USB cables for sale (the other one in the picture already sold). I’m the original owner and have used it for about a year.
From Synergistic Research – “The new Atmosphere X Reference USB like it’s little brother is voiced to deliver natural musicality so you’ll enjoy listening for hours, even when streaming on Tidal and Spotify, with no loss of resolution or soundstage scale and realism. To this end, our highest performance Atmosphere X Reference USB cable comes equipped with a ground plane running from tip to tip and a shield that can be tied direct to ground for the lowest noise floor possible. Engineered to work with included Blue and Red UEF Tuning Circuits you fine-tune the sound of your system from the precise detail and air when using the Blue circuit, to musical warmth and liquidity when the Red circuit is connected. Other design features include UEF Graphene Shielding, a new conductor alloy, a new Atmosphere X Shielding Matrix, and a new conditioning process first developed for our Blue Fuses. The sum of these design decisions created a USB cable that sets a new standard for ultra resolution and holographic scale combined with a stress-free emotional connection to your favorite music.”
