ISP D-CAT Power Amp Technology

Apologies in advance for the lack of diagrams, but would someone be able to de-mystify the contents of this document for me? I spoke with the main inventor a couple months back, and all I remember from the conversation is that the amp is a hybrid between Class D and Class AB amps, and something about a "bootstrap" configuration and more current leading to better low frequency transient reproduction.

Rump bump.

I should also add that I read something somewhere about this power amp not requiring a bias pot and being able to drive loads down to 0.5 ohms. Again, I apologize for my lack of clarity and helpfulness here (and I'm certain I'm not presenting the full picture, so I may need to send ISP an email to clarify the exact details of the technology.)
