This is something I've become very sensitive to, meaning that most systems get the thumbs down immediately when I listen ...

I see yus guys haven't bothered to read Absolute Listening Tests-Further Progress

Not that I'd expect anyone to believe stuff from beach bums.

The interesting bits are what was expected and what was unexpected. It shows the Room Interface Profile as most important and practically everything we measure at 1m on treble unit axis bla bla (or your favourite prejudice) as almost irrelevant. In fact Tom Danley's youTube link shows that quite clearly.

The best part (I prefer good headphones for this) is that you capture sounds around your house that you are totally familiar with and at times they can make the hair stand on the back of your neck (if your also prone to that kind of response).

I used to have some recordings on our old web site using a stereo capture array thing I am working on. Nothing exciting just stuff from around the yard like a train, motorcycle and fireworks. It’s still kind of cumbersome to move around so these were “organic” sounds haha. I hope they will eventually put them back up when the webtoids are working on it, I was pleased with the “space” they captured.
There's a treasure chest of such recordings at ambisonia.com These are Ambisonic surround recordings and you need a decoder to hear them in stereo, your zillion.1 system or headphones. Try VVM or Harpex.

ajh for classical, pwhodges for choral stuff, soundmanjohn for effects .. though I'm wary of typecasting as there's loadsa good stuff here. No compression and some of the best recordings I know.

Let me know what you think if you have a listen.

I tried, but it looks like some private club restricted access.

Alas, as a beach bum, I've been chucked out of the club. But I'm sure Mr. Danley is still a member .. as are those of you with stocks of 62' Yquem. I'm drooling as I type this.

That the measured performance @ 1m on treble axis (or whatever your prejudice is) is good enough on a small number of 'good' speakers. This applies to 'advanced' measurements like waterfalls & other bells & whistles too, some of which I've been privileged to help develop.

Not perfect, but the faults here are NOT what makes a speaker sound like a speaker instead of the 'real thing'.

The Room Interface Profile is the sonic signature of the speaker which remains unchanged when you listen to it in different rooms. This is clearly audible and allows experienced listeners to identify a speaker they are familiar with. ie This is what makes a speaker sound like a speaker.

Thanks for that ...

Next problem, "Room Interface Profile", gives me 3 results in Google, all useless ...
