Another couple of cabs I'd thumbs-up based on their power supplies would be ones from Erica and Pittsburgh. In the latter case (no pun intended), those are Monorocket designs, and Monorocket was always known for MASSIVE power overspeccing. The Pitt cabs are no exception. And the Erica stuff also goes overboard on amperage...even their 1 x 84 skiffs sport 1.25A 12V rails!
