Unless physical size (very small) is a basic requirement?
I would suggest the Nelson Pass Amp Camp Amp kit. Find it in the diyaudio 'store' section either 130$ sans cases but with twin Supplies included, or 260$ with cases. (when available, it's a fast seller)
You will be unlikely to find a better sounding Amp.. pretty well anywhere. IMO.

The Amp Camp Amp (ACA) is class A at 5 watts power. Unless you have very sensitive speakers, that may not fit the bill. A great amp though if class A is what you are looking for. OP asked for class D amp schematic. You can order all the parts yourself for the ACA for about $40 not including heat sink and case. A very inexpensive way to get into a legendary class A Nelson Pass design.

My vote is for the DUG TPA3116D2 in PBTL (100 watts into 2 ohms mono) so you need two for stereo.

If you want to get an idea of what this amp is capable of, get a premade one for $20 - look in this thread:

Then mod it or make it from scratch, or make it with your own choice of components per the DUG PCB.
