@blue_collar_audio_guy OFC copper interconnects in varying solid or stranded designs (imo) tend to have a slightly more raspy sound and less smooth sound compared to true Ohno OCC or Pure Cardas Copper in my system. I've re-tested it countless times over decades with various brands. It was the one small thing I could change in my old SS systems.
On the flip side, some brands with OCC crystal copper can smooth out the sound greatly with no grain which can also present this odd sense of a loss of texture and some tone loss compared to some higher end OFC or other pure copper stranded cables. Striking that midpoint is key and there are tradeoffs in both spectrums, imo. Start with lower cost demo/loaner cables if you can, might get lucky and find a good one!
To combat this, some designers will intermix a single silver strand or plated silver over copper, and the results varies yet again with different pros/cons. One of the reasons I went back to Cardas pure copper multi-stranded designs and have never looked back.
Results do seem to vary from one designer/manufacturer to the next. For those who cannot hear a difference in their particular systems, or non-belivers, well they get to save real $$$ and good for them - YMMY. 👍
