Low THD PWM audio amp, DIY friendly

DIY as in assemble yourself? I tried finding parts or info or schematics or designs for their other amps, but nothing of any real detail seems available. Cool potential offering here, but based on their other offerings, looks like it will probably be phenomenally expensive even in kit form. And not at all in the kind of hacker-ish open form we might hope.

It'd be great to see some real open-source wonkery start eith some of the modern chipamp chips. TI's latest tpa3255 is a beastly chip, and there's some pretty good sub $100 ~400W designs about based on it's advanced magic. Trying to get a bit more geeky, to share & tune & profile boards & builds together for modern chip-amps could really open up some new frontiers of affordable quality.

My money is on "tax and/or tariff avoidance ploy."

Taxes and tariffs are responsible for "tariff engineering" to get around the definitions used for many tariffs. For example, a lot of early DSLRs couldn't record video continuously for more than 20 minutes, because this would qualify them as camcorders.

Either that or they're selling this for people who have the skills to create a chassis (or have one made) and then put these guts into. Sort of a "crate engine" of the audio world, I guess.

I liked the "affordable" claims. The complete kit is $1200...
