It's funny, this thread conjured up memories of my old store in Louisville.
The way I would evaluate anything was first, unkown, as to which was which, then, do an A/B/A. I would make notes sometimes, but usually, and this is a curse rather than a blessing usually, I would immediately hear the differences, for good or bad. Now, to be clear, I NEVER cared which was better, I only wanted to know.
This was an instructive time in my audio development, in that it taught me patience, and let me be self assured. One of the posters on here who shall remain nameless, hates me because I hear in seconds, what it takes him hours to ferret out. And trust me on this ALL of his tests are blindfold tests, and he's really good.
I only wish, God love him, that my brother and I could have a discussion about possibilities for a change, rather than onlt dwelling on that which is known. The only way we discover new things is to go out on that limb. When, (yes I am a commercial poster) I voiced my speakers, I used the Sound Labs as well as my inner reference of music as a musician for decades, as the control. I never questioned the outcome with caps etc, or wiring, regardless of where it led, I only accepted the findings, as sounding either better or not as good, regardless of what was SUPPOSED to be according to the hype or accepted wisdom.
Most of you out there when listening to power cords no doubt have had the same experience. One is better than another, WHY? Maybe a better plug, and so on, but who cares ultimately. If it sounds better it IS better, for you. This is why speaker designers pull their hair out. They are all convinced that theirs are better, no doubt, but since this IS SUBJECTIVE, we'll always agree to disagree, I guess.
Thanks, keep em coming, you guys are interesting.
