Default Any Suggestions?


I got asked for an Amp ... a friend of mine wants me to build a Class-D amp with the highest possible output power (I guess he's talking about something over 600 watts), the best possible performance (THD+N about 1% according to him ... ) and the lowest possible number of parts (he said it should fit on a thumbnail ... )
I know this is impossible, but, well ... he doesnt. So do you have any suggestions on this project?

For a start, let's leave the question for money unanswered ...
