I agree, because there is no enough possibilities for evaluation. I am complete new regarded various topologies and therefore I like discrete designs (at least with standart comparator ICs) combinied with detailled circuit description

I have start follow threads - first with not finished schematic of an ICEPOWER module, that I had get for repair
Sanyo/B&O Icepower 200AC Rev.D, schematic about rev. engin., not complete finished
Ultimate sounded Class D for diy without custom made IC's like Tripath TA2020

and about this threads I have found discrete class-D topologies:
TC Electronics Switch amp
newclassd: the better class d amp?
