He'd originally released his own module with some sort of stepped rails (class D-G?).
Very shortly after that it was announced he'd release a "THX certified" amp based on Hypex modules. So plug a few of their modules in, pay for certification and cross your fingers?
Those modules on that page don't look like Hypex stuff to me though, so I'm guessing it's either the old class dg or .... maybe something different. I don't know how the THX thing turned out.
Patrik (pabo) is rather clever so I'll imagine his modules are rather clever also. I have met him and he seems to know what he is talking about.
And better PSU wiring on that finished proto, and why is he using dual XO's on that amp, is it a mixed digital/analog design?

I guess, Pabo's modules have pretty low idle consumption (D2PAK in use), so if he'll reduce dead time ( for example, up to 80mA of the idle current), specs will be more impressive too.

Yep, that big hump looks like poor deadtime control to me too. Looks like he tried compensating for it via other means?

maybe via other means, but "poor deadtime control" is a wrong words, just a dead time choice optimised for efficiency (IMHO). Let's ask Pabo. 🙂
