Has anybody known d2audio chips:

Spec-wise looks impresive, better than TI TAS5015/12. They made 2 chips, one for stereo hifi, and the other for home teater. I wonder whether theys are diy-able or not, I couldn't find any datasheet... 🙄

Hi
This is all costom chip, so there is possibility that you can't even buy them... No datasheet because it is costom,....

There seem to be a few versions of those.
At my glance, theres 2 seriers 814 and 914, in total 5 chips.
The 914 seems to perform better, and supports more channels. The 814 supports 4 channels, and should be tandemd for 7.1-operation.
The 814-series is probably targeted at TV-speakers, and the 914 at surround amps.
D2-91413-LR seems to be the most hi-end version of the lot.
D2-81412-LR could probably be used for a 2 channel 100w-amp, acording to http://www.d2audio.com/files/D2-PS-MXS100-50-v1.2.0-web.pdf

They're better spec-wise because they incorporate feedback unlike the TI chips.
Marketing babble: "Digital feedback compensates for speaker variation."
Translation: The analog post filter feedback signal goes through an ADC.
Marketing babble: "Digital power supply correction (DPSC) addresses power supply fluctuation."
Translation: They use a regulated switching supply.
