Is "detailed" audiophile code for too much treble?

Dear OP:

Yes. "Detailed" is definitely code for too much treble.

Not always, and not in every system. But it’s code for too much treble way too often to be ignored, IMO.

I’ve found a number of audio components that managed to be very detailed (ie, resolving) without being bright or edgy..But it took years of looking. Components like that are unicorns.

There’s nothing magical about any of this. Components like this are typically not designed with ideal bench test measurements in mind. They happen when designers purposefully "voice" components to sound like real music, not exaggerated imitations of it. I believe it’s harder (time & $$ cost) to design in that manner

A few examples. All are quite resolving, also quite musical w/o exaggerated treble::

• (NOS DAC) Metrum Onyx
• (speakers) ATC SCM12 Pro passive monitors
• (speaker amps) Bel Canto 600M monoblocks
• (headphone amp/preamp) Violectric V281
• (headphones) ZMF Caldera
