Best SQ I've had from a chipamp has been from TDA8932.

That’s classD, I’m not sure I would call it a chipamp. But I’m also biased for our own EC7293. Straight chip though 7297 still seems supreme.

Could you specify 'best'?
Low cost? High reliability? High power output? Low noise floor? High efficiency?

Chipamps are only classAB in your estimation?

I agree that for class D, TDA8932 is very good. So is TPA325x. Chip-amp or not, they are amplifiers in a single chip.
For class AB, LM3886 is among the best. LM1876 is fine as well for lower power levels. TDA729x are alternatives for varying power levels.
For finished DIY amplifier boards, Neurochrome has some very performant amplifiers. The EC7293 seems based on TDA7293s and using a similar composite amplifier concept as Neurochrome. These finished amplifier boards are for use "as is" as large experience has been put in for optimizing the performance.

I agree, I forgot to mention TPA3220/1 which has I think more potential (though less power ) than TPA325x due to the ability to use entirely external PSU regulation.

Well, this forum has them in seperate sections, so Iíll roll with it and say chipamps are not classD - likely classAB.
