Basically, agreed. I only posed the show scenario because it was the archetype of the "drive-by" as opposed to the more time consuming, and ultimately more informative, effort to listen using a variety of material. I largely avoid audiophile spectaculars-- records I'm familiar with help, but I want to find the seams-- and there will be some-- if you listen on enough material. I heard a multi-million dollar system right before the lockdown thing, and one of the records I had managed to avoid for a few years was "Dreaming of Dean"-- not that I have anything against the guy- he was probably fun to party with back in the Rat Pack days- but it was an audiophile trope that I avoided. And guess what the host put on? I started laughing, and then explained that "he got me" by playing that record. An amusing anecdote at best. None of this is new news-- you've probably been to more shows recently than me. (I'm not in the hardware side of the industry, in fact, I'm retired, but I did my share of shows in the day and only raised it to make a point that reinforces what you said)-- you have to listen to a wide range of material to get a real handle on a piece of gear in a controlled environment, with "controlled" variables. That usually means "in my system" though in years past, I was familiar enough with a few other systems that I could trust what I was hearing reflected clearly on the component, record or accessory in issue.
