Stefan AudioArt Custom Air-Suspended Endorphin USB Cable

For sale is my cherished Stefan AudioArt USB cable custom made for me in 2m length using the air-suspension technology from his TOTL speaker cables and interconnects. This is an incredibly natural-sounding cable with perfect tone and endless frequency extension, overall an extremely analog presentation with no glare or tonal anomalies. I would not be selling this if I weren't selling my entire 2-channel rig. I am keeping one of these for my headphone rig. Original price was $200 more than the normal USB cable, so $799. Buyer to pay shipping and fees. Cheers and thanks for looking. Here is a description from the website:

the performance and musicality of your system. The Endorphin will easily
outperforms USB cable costing three and four times the price as it is

The most important information we have gained in over 12 years of
headphone cable design comes from our customers. Hundreds of serious
listeners have reported back to us indicating that the sum of all the
improvements offered by our audiophile, high-end and ultra high-end
headphone cables translates into a unique emotionally involved listening
experience.

The heart of new Endorphin is a uniquely
engineered conductive surface formula allowing the pure, open, full body
signature. We designed and tested dozens of our own conductive surface
formulas which consisted of the purest copper available combined with
proprietary conductive enhancing material using 60% less non-conductive
material which lowers the resistance to the audio signal and increases
the richness, clarity and definition across the audio spectrum. In
addition the soundstage presentation opens-up to expose the listener to
music which becomes truly engaging and captivating.
