I think the silence says, "if you look a little more, you will find many projects here.

What ever design you pick, lots of parallel output transistors is nice to see. 8 ohms doesn't sound like the typical load DJ's are driving these days. I thought it was all about 4 ohm and 2 ohm capabilities.

Avoid the banks of output transistors and try Class D! D seems to me, a clear "get out of jail card" for folks haulin' gear around all the time. High power, high efficiency in a compact and near light weight enclosure seems very attractive to me. I would not build one from scratch but I would take a modular approach and purchase D-amps, power supply and a chassis, then assemble it myself.

UCD Modules from HYPEX seem to be a good choice. Lots of dialog about this technology over here.
