Whenever I've attended an event where cables are compared and there has been a component change a person immediately pronounces that cable a is better than cable b. This usually occurs within 3 - 4 seconds. When this occurs I actually feel pressured to agree with what other people are saying.
Yeah--I know exactly what you mean. And it's pretty frustrating. Over time, I actually grew to disdain all the 'wizards of smart' with 'golden ears'--because, to me, the data just wasn't there.
Then I began reading published accounts of some "cable tests", where it was a blind A-A comparison. (The testers told the subjects that they had changed cables, but they hadn't. In another "experiment", they actually did change cables, but they were the same make/model/brand, but just put in a different color Teflex.) In both cases, the 'wizards of smart with golden ears' wrote pages on the difference nuances between the cable.
After reading these accounts, and as I gained more education relative to the actual physics and (true) science behind cables, components and speaker-building, I became comfortable calling it what it is. There is a shred of validity, but much (if not most) of it is a bunch of insecure people trying to be seen as a 'wizard of smart with a golden ear'.
Life became much more enjoyable when I stopped hanging around those folks--because I began to focus on enjoying the music, rather than trying to pick apart "flaws" or hear things that don't exist.
