I'm changing my way of thinking just a wee bit. I have a pair of small AR speakers sitting around doing nothing. Their footprint is just about the same size as any of these powered speakers. I can use these for the desktop, but then I need an amplifier with an integrated USB DAC that is small enough to sit on the desktop and provide enough power to drive these speakers.
Class D to the rescue I think. Does anyone know of one that is inexpensive and have at least 25 watts of power (preferably more)?
I saw this one over at HifiMeDIY.com and it looks very interesting. It also works with higher sampling rates than standard CD.
