I'm suggesting this sudden push by Stereophile to promote expensive cables might be evidence that it is?See no evidence for that. People might say that speakers and amplifiers meet a saturated market, but seemingly not stuff like cables. People who have everything still like to tweak and fiddle with accessories.
I agree that, traditionally, cables have been a less expensive way to fiddle with the system rather than swap boxes or, god forbid, just use the damn thing to listen to music.
It's not impossible that the advertisers have requested a push on this front due to sales sagging. We aren't likely to be made privy to that data, but in recent years the existing paradigm of 'everything matters' has been shaken, if not overturned, due to this forum and other sceptical platforms.
Of course it might not be and it's just some random subject picked arbitrarily to pad out the editorial content. I sort of doubt that's the case though.
