Nice to see you here Mark!
Again, nice job on the video interview and I really appreciated seeing your perspective, especially on such a popular audiophile channel.
To expand on the comment I made earlier:
Again, I liked very much how you brought up the need to be skeptical about what we seem to perceive when trying out new pieces of gear - and the reminder to the audience that there's a lot of processing going on and interpretation in our brains, where things can go askew.
If the skeptic wants to talk to the Believe Your Ears part of the audiophile audience, I think we have to be careful about fulfilling their caricatures. Their big rag on folks like those here is "They Don't Use Their Ears" or "They Don't Trust Their Ears!" That seems utterly mindboggling to them, and to hear just that repeated back I'm sure (and as I saw in some of the comments) gets an "aha, figured so, we were right all along" confirming their bafflement on why anyone would want to be an "objectivist." Distrusting yourself seems like such a drag!
So if we only concentrate on how our perception can be fooled we can leave the impression of a hyper-skepticism that just doesn't make sense to the person watching. "What do you mean I can't trust my ears? I use my ears all day long and they WORK! How can I take this guy seriously?"
Personally I like to start out acknowledging (what may seem too obvious, but might need saying anyway), that yes, of course, our ears work. Yes of course we can in a general sense put some confidence in our hearing. It's quite a remarkable system, and it helps us navigate the world in an amazing way!
BUT....if you REALLY want to be careful about drawing a conclusion, it's worth remembering we really do have this variable regarding our perceptual biases, and ...by the very nature of bias...how easily it slips in to our perception without us knowing it. And it really can play a role in any thing we are perceiving.
As I like to say, at any one moment countless people are making erroneous inferences from their perception. Right now there are folks who believe they were anally probed by aliens in the middle of the night. You don't think we audiophiles can sometimes imagine some added "midrange glare?"
There's a reason the scientific method arose. We get our most reliable knowledge from the method that takes the problem of bias seriously.
As I've argued on this forum numerous times, I like to recognize pragmatism along with skepticism. That is, scale my confidence with the nature of an audio claim, or what I think I'm hearing. If I audition two speakers at the same audio shop and they seem to have characteristics that distinguish them from each other, yes even in that case bias (e.g. how they look) could be playing a role. And if we really wanted to be SURE about what was going on, measurements (and in the best scenario, combined with blind comparison) would help pin that down. But, in a practical sense, speakers do sound different and it's entirely plausible I'm hearing real differences, so...pragmatically I'm fine with "what I seem to hear."
The more something leads in to technically dubious or controversial areas, e.g. differences between AC cables or whatever, the more "extraordinary" the claim, the stronger and more careful evidence I'd want. So in that case I wouldn't just trust what I, or some other audiophile, "hears." It's a higher bar to cross.
(And it's why I have indeed put AC cables...even ones that I seemed to hear a difference between...to blind tests. And under those conditions I could no longer detect any difference).
Cheers, and once again welcome!
Oh, and sometimes my floor looks like yours, with all the tape marks for speaker positions, and I don't even own maggies! I just like to experiment.
