I used to be a mobile DJ too, and I never even heard of this brand...
Is this for real? This stuff indeed looks like junk -- like the "bargain basement" gear you used to find at The Wiz or Crazy Eddie's, which claimed to be awesome...thousands of watts of power...no distortion...
Car audio used to be riddled -- and still is -- with this kind of product; at any rate, I wouldn't buy, especially, that receiver...does it even mention onboard decoding for surround formats? What is it supposed to be used for?
