auxinput...so, how about just using No. 10/2 Romex cable...single Cu conductor, solid, unstranded? I have about 50ft left over from running 240V service for a wall heater...always curious how simple electrical wire would work in home stereo setup. Also, there is a stranded version as well - THHN #10, 19-strand pure Cu...cheap enough at Home Depot...not being sarky, a legitimate query.Yes - it will work, but do you want the best out of your system?
How well it works depends on the origin of the wire. Not all Romex is equal
Good Cables are designed to combat many EMI/RFI effects within the cable itself - Romex is not - the result is a "smeared" sound that lacks clarity, details, dynamics AND (guess what) bass extension
But give it a whirl and then try a good cable - the difference should amaze you.
Despite many opinions to the contrary - a thicker gauge is not always better - I was using 10 gauge - I now use 16/13 Gauge (i.e. Signal/Neutral conductors) AND I get better bass performance than the 10 gauge.
It’s all about the cable geometry - i.e. how the conductors are positioned with respect to each other AND the gauge of the signal and neutral conductors - it is best if the neutral is a heavier gauge than the signal.
It’s taken me a couple of years of tinkering with cables to come up with this approach on my Helix cables, I even tried Romex (not good), so I speak from experience.
The cables I recommend in my post above are extremely good performers. There is little difference between them in sound quality. One is commercially available, the other is a DIY project.
But feel free to try the Romex - you may not hear the difference, which would save you a bundle
