Default Crown BCA as half bridge?

I'm looking at some Crown app notes about the Balanced Current Amplifier and is thinking about giving it a try, however i dont expect any sound quality worth jack from it.

I was thinking 300-400kHz switching frequency which is then doubled to 600-800kHz by the BCA topology, which would essentially make it the same performance as a 600-800kHz class D amp.

Its interesting so i'd like to experiment with it. I've seen it before but never thought much about it.

Good idea,I like this topology,it has very high damp factor,I have try the circuit years ago,works well,

Double frequency concept is not correct, Only my thought,because many class D circuit work at BD mode ,like crown double fequency concept.

when bridged two ir class D (400Khz),could it be said 800Khz main frequency

?

I may try this topology sometime. But for now im gonna concentrate on the prototype i designed before based on the 25-1200w ucd.
