Couldn’t agree with you more!
Thanks to my work, I’ve spent countless hours in recording studios watching music being made. I’ve also attended a ton of live events at outdoor venues, auditoriums and jazz clubs. To my ears, no piece of equipment can match the real thing.
The main factors I use to judge a system are tone, timbre and timing;
musicality, if you will. Soundstage height, width, depth, imaging, micro details, explosive dynamics, silent backgrounds, etc are icing on the cake. If I forget to focus on the minutiae and just get lost in the music, I know I’m listening to a great system.
The only time I look at measurements is when I’m trying to match amps and speakers. An 86db 4 ohm bookshelf is not something I’d pair with a tube amp. For me, music is like food - either I like a dish or I don’t. Waxing eloquent about how it was prepared or the quality of the ingredients does nothing for me. If you need spec sheets to tell you your system is good, your ears have lost their tastebuds
