Finished this Sure 500W Class D power amp. and sounding great. A lot of work and as you can see pretty cramped under the bonnet. There is 40,000uf of caps and 2 X 300W power trannies. The max voltage you can feed this module is 52V. My PS develops 54V and can deliver 16A (theoretically). It weighs in at just over 10kg. With my ear to the speaker a very slight hiss but at 1m, nothing.Sound stage is razor sharp with central images etched into marble. I have never heard anything so precise. The overall sound may be a little forward but this is comparing with a 300B tube amp. Bass is extensive and full-on. And this baby plays loud. Way too loud for my 30W speakers. No distortion or strain when cranked. It should deliver about 200Wpc with under 1% distortion. It is clean, clear but doesn't feel too analytic. Decay is crazy long and reverb and echo like I have never heard anywhere. Spending time now burning it in. Robusto is a crazy good amp.
