Hi,

check this site. They sell an excellent 180W-classD module already and will offer a similar, but 400W module in a few weeks for a very(!) fair price.

Regards, Timo

Hi

Check out Randy Slone's site.
http://www.sealelectronics.com/

In the moment I'm building up this OPTIMOS-Amp.

You can ask Randy for the improved schematic.

I am not a fan of class D BUT if you choose that route Tripath makes a class T evaluation boards. Just add a power supply and a chassis and you have a new born amp
