Is it me or new audio gear is too perfect and give ear fatigue?

Strongly disagree that most new gear is bright. It really boils down to speaker choice and system matching. For example, my current DAC is a Chinese DAC that measures extremely well. I usually at listen at around 84 db volume and I don’t find it bright at all; DAC pretty much matches the tonality of my turntable. 

For example, my current DAC is a Chinese DAC that measures extremely well.

@arize84 Topping makes some DACs that are quite smooth on top and measure well and are also inexpensive. High end audio is not driven by cost, its driven by intent. However even though a source might work just fine that says nothing about design issues in a power amp. For example if its lacking in gain bandwidth product and also has feedback it will sound bright and harsh at higher power levels. This is because the feedback will fall off at higher frequencies causing an increase in distortion. This particular problem is endemic with 99% of all solid state amps made.

@ghdprentice , soundstage and imaging is what I prefer.  I guess the late 70s equipment and some 80s is what floats my boat.  I have not gotten lucky to probably hear all equipment, I just stuck with brands that I remember and like.  With the internet, I can read more about vintage and new gear, also check on Youtube to hear how it sounds (compressed down).  There is something about those Pioneers SX receivers that has that imaging that keeps me engage to listening to music.

@carlsbad , agree, certain DACS are better sounding.  I also picked up a Freya +  I'm happy using the Schiit DAC and the Yamaha CDS2100 CD DAC.  Always wanted a pair of Thiel's to try.  I lust as the catalogs when they use to show his models of speakers.

Again, not trying to offend anyone on new gear, I just feel the specs are near perfect in the tonality.

It certainly is very easy these days to build systems that have way too much high frequency energy and/or is fatiguing. The two are correlated but not equivalent - SOME gear has a perceived excess of treble / HF energy, but is of such a very high quality (and so smooth) that it doesn’t cause me fatigue. Some examples: Stax headphones like the SR-009, Ortofon’s high-end MCs: A90 / Windfeld Ti. That’s not typical though. And you still don’t want to stack multiple components like this, because the result will be musically unbalanced.

This behavior is definitely not just driven by room acoustics - it’s characteristic of the components themselves. I hear the same sonic footprint when I move a component into a buddy’s system. And of course headphones (which I have tons of experience with) don’t have this variable at all.

System matching, to ensure a good resulting balance, is crucial. This isn’t something you can reasonably glean from FR graphs or other measurements. I don’t know of a way other than trial & error.
