I would suggest the book "power amplifiers ..." of S.Crips. I think that it
is very good for understanding the theory and design practices of power amplifiers.

Best regards,

Theory may be seen on the:

Simple schematics:

DSP version is more expensive and sound quality is bad in comparison with analog version.

Read theory: hem.passagen.se/johanps/audioexperiment/class_D.htm
