As an electrical engineer, and somebody who has a pretty extensive knowledge about wiring. I see absolutely no way ’ultra expensive’ high quality oxygen free stranded wire, regardless of the amount of strands it has, will in (short lengths especially) make any difference whatsoever.
With analog cables, sheilding is extremely important so differences in quality would surely effect the noise floor...
Please, somebody show me proof as to how this phenomenon of higher fidelity will be the result of me spending thousands on several meters of cable. Just because I don’t see how it’s possible doesn’t mean it isn’t, but none of my professors at RPI would jump on this bandwagon.
