The TI part is hardly a breakthrough. This one with built in SRC, ADC and DSP has been out for a while and is in quite a few consumer products already.

Does it have feedback?
Maybe I´m wrong, but in my opinion this is the reason why AB still dominates the chip amp market, and why the Tripath failed, despite of its sonic superiority.

You may call me stupid but I don't get what you want to tell us with this statement since both of these use feedback.
Regarding breakthrough:
I think the closer to a linear amp a switching amp behaves the more it will succeed.

I don´t know anything about the Crystal, but the Tripath didn´t have the power transistors in the feedback loop, making it very load (and PSU) dependent.
I don't know about the "chip-only" solutions but the high-power versions (i.e. the modulator/driver modules that you had to use with a pair of power MOSFETs) definitely used feedback from the power stage. What they didn't was use was post-filter feedback for unknown reasons.

TI also don´t have post-filter feedback, but they claim their chip even achives good results with the backlight PSU of an LCD TV.
