Maybe in the future there will be some slick class D chipsets that will allow this, but for right now...it's just not possible. We hand build all of our products here in California, which is much more expensive than having them built in an offshore sweatshop. All of our metal work, circuit boards, etc. are also custom made locally...it costs more, but "ya get what ya pay for". I doubt you'll find a decent US made amp for $500.
