Good thread Erik.
Building your own class D amps is an excellent way to get hi-end sound quality at an affordable price. The performance levels of the more recent class D modules are, in my opinion, outstanding and this technology has broken the mold on how to attain high quality sound from a home audio system.
Previously, the only known and accepted method consisted of using large, heavy and expensive traditional class A solid-state or tube amps or ss class AB amps to drive the often very demanding requirements of the various high quality home speakers typically used.
Class D amps have broken, smashed?, the traditional mold of how to attain excellent home audio quality for both home theater and music. Compared to traditional amps, they're smaller, lighter, electrically more efficient, run cooler, less expensive and I believe sound just as good or better.
What's not to like, right? I've been using them in my system for about 4 yrs now and can't think of anything. Class D amps are really wonderful.
So, I completely agree with Erik's recommendation of building class D module based amps. You can build your own, have them built for you or buy completed amps using these modules under various brand names.
Enjoy,
Tim
