Hi
I consider building or buy a new class d amplifier based on one of many DIY chips.
I want to rely on the most audiophile chip I can get.
What would you recommend? maybe TPA 325x, TDA7498E, TA2022, TA2024, or maybe another chip?

TPA3220 and TDA8932 are most 'audiophile' in my experience as their signal stages can operate from regulators which aren't on-chip. I haven't tried all those in your list mind.
Abraxalito is one of the members with the largest experience in different class D chips. I know the TDA8932 and I find it exceptionally good as well. TPA325x are widely known as highly performing chips. If you can find one, the Tripath top-model TA3020 was known to be fantastic. The TPA3220 I do not know but there I trust abraxalito.
I always have a problem with the word "most" (...the most audiophile...) in this context because it ignores the very important element of subjectivity for sound quality.
At least our recommendations can serve as a guideline.

The word audiophile is very loaded, some(many?) of us will equate it with audiophool or fashion-victim in many contexts (overpriced capacitors, turntables made of solid granite, etc etc).
My recommendation is to say high-performance / performant if you mean that, list your performance requirements if can too, that's nice and concrete (if you want 50+W, a 20W chip isn't useful to you however good it is).

I agree, I want to drive Mistral SAG 350 speakers, with the following spec: 88 db, 4 ohm.
I prefer an amplifier on the warm side fo the sound.
which of the above chips could be best for me?
How about the TAS5825M, in I2S input amplifier? Keeps everything in the digital domain up to the speaker connections. You cant choose your own DAC, but if TI did a good job converting the audio digital word stream into a 384 - 768 kHz pulse width, it should sound pretty good. I'm listening to one right now and I like it!
I ordered an TPA3251 and just listening to an Connex TA2022 that I dust of since my TA3020 died, my fault, with amazing mid!
Not so sure about the highs but better than any TPA3118 so even if its old its very good.
Is AC better then DC?
I run AC 30V on TA3022.

Yes, I recently swapped out 2 different TPA3251 amps, and a Breeze TPA3116, for my old Charlize2 TA2020 - this old amp is not as detailed as those, but it's pleasantly less clinical, and so much more musical!
"AC" in this case simply means that you are using the onboard rectifier, to convert your AC input to +/- DC.
Yes you are ofcourse right but is it any advantage with +-DC driven amps?
Most new is only DC.
