What can you do with nine channels of high-current audio power?
First of all, you can put together a mind-blowing surround sound system with five speakers up front and four in the rear.
If you only need five channels for surround sound, you can use two of the other four to biamp your front left and right speakers. If you have speakers that can handle biamplification, and you haven't tried it yet, you're in for a treat.
Finally, you could devote some of the channels to your multi-room audio system.
