That’s one approach. Another is to experiment for yourself, and then decide.
Therein lies the rub. Experimenting takes time and effort, and the expected benefits are quite modest at best, unless of course an aftermarket cord happens to correct some kind of existing imbalance or condition.
It is understandable that folks who invested half a million or more in a finely curated and polished core system and sources would be tempted to experiment with audiophile power cords, if only for completeness’s sake / leaving no stones unturned.
But my system is nowhere near that level of refinement; although I have to say I am quite pleased with its current end sound, I still have a ways to go to optimize its core, let alone sources, so I feel that for me to experiment with cables at this point in time would be not only wasteful of my time but also counterproductive to the optimization end goal.
That goal is better served by not changing cables that are in place, thereby eliminating variables that would otherwise muck up the proceedings.
Additionally, I believe that a well balanced and highly refined system does not need, or want, coloration coming from its cables. Folks who use cables as tone controls should really complete their systems first; then they might find that transparent / neutral cables are simply more appropriate.
Your point is well taken, but I trust Nelson Pass for now and will verify later.
