I would not be inclined to use a pro audio amp in my home system (though I have done it before), but being a bass player (and sometimes sound man), and having played out pretty regularly for over 15 years, my favorite amp for the money is QSC. The PLX series is just incredible. However, these do use a fan, which is fairly loud. I think that the Stewart digital amps don't use a fan, and sound very good, though I hear they have reliability issues. I think you'd have a much easier time finding a good high end home audio amp than a fanless pro audio amp that fits your needs.
