While an AES/EBU digital cable should be designed to match the intended 110 ohm impedance, this implementation will not due to a lack of precision in such a hand twisted design. The spacing of conductors and dielectric would have to be made with a much higher level of precision than can be achieved by hand twisting two cables. I'm not saying that it can't sound good in a specific application, but it will not be operating as intended without the precise 110 ohm impedance loading to result in lowest possible jitter and optimized timing of the digital signal.

Retail price was 100 USD as previous owner told me.
