How do these things sound?  ANy recommendations regarding sound quality on building stereo power amp? Maybe about 100w max per channel.  I do intend to you a switching power supply. I have used 15W Class D amps and I think they sound ok. But they seem to get a bad rap.

The LM serie by National is better liked by discerning music enthusiasts.
The most power you can get with an LM3886 is 68W, but you can parallel and/or bridge them for more power. National even show you how to do it in their application notes.

And switching power supply can be very noisy. Most people simply with a simple RC filter for the power supply, some go regulated (the high current demand makes it a bit more complicated, they don't exactly make 10A voltage regulators)
