The idea that all-from-same-manufacturer cables can be audibly superior (since such difference is not measurable mechanically, and hasn’t been demonstrated as real by way of consumer preference studies) vs. a mix in a hifi system assumes the given manufacturer is equally understanding and competent of the requirements for all stages of signal pathway, and also more so than any competitor. To me and the rules of probability, doubt is looming. For anything that’s not quantifiable or patented but “sounds better” to some folks, that implies (assuming it’s actually real) the tech is superior by luck of design, and when that luck must extend to different forms of interconnects equally, well, also unlikely.
I have “gone whole hog” or “gone all out” or whatever real world colloquialism one might see fit to use, with audio cables twice, and including the power cords once (and in that case, all of the kit chain’s power supplies were also from the same manufacturer).
Predictable audible difference was not to be found in my two anecdotal cases, but alas I’m one of those a folks who does value an audio blind test over blindly testing my wallet. To each their own.
