things like these are why I find it a bit silly to spend ridiculous amountts of money on dacs and amps and buy hi res audio when what youre paying for is usually extension to ~30k if you’re lucky that the equipment reaches that and power supply hum and ground loops which we thankfully can’t hear. The music is produced by humans on workhorse tried and tested professional gear and producers make mistakes and get fooled all the time anyway; the thought of a $5000 dac doing anything that a layman audiophile can hear, usually in their 40s or above, that was magically printed even though the sound engineer couldnt even hear it, is something I think only audio enthusiasts still propose. Imagine if people were buying TVs and claiming they can see so much more details than what the editor put into the movie or had no calibration standards and instead everyone just chose a TV on a whim cause all eyes are different
