Very good 280 1

Works great, surround means from time to time but it's clearly not replace a 5.1 or 7.1.
The fact that the subwoofer is built into the amp is great because it takes up much less space. The connections are easy. and I ironed 5.1 without problems a few months later with satelite speaker artsound, rendering is superb.
The bass seem weak at first but more than enough for a very good rendering in movies and personally I do not put them thoroughly.
