I use pro audio power amps in my home theater. They provide tons of power for little money. There is one major downside though. Most models feature noisy fans, and for a good reason – pro audio power amps are often run at their limits, and many manufacturers prefer to err on the side of caution. For home use though, you can usually get away with replacing the built-in fans with quieter ones…| Lack of Imagination
