its a 2 channel, rx 570 reciever, i have two sets of speakers a set csr-9;s and ar51's by technics,now the only thing is the speakers are great, bnut the reciever plus the speakers dont really sound to hot. i want loud music, (no prblem) but with alot of bass, the only thing is if i have it on the one channel, the csr-9s cant handle it too well, anywhere in the high volume range the woofers go into a constant shake/shudder. i dont know how to fix thi, i think i need a new cd changer too, the one i have when on, emits a buzzing sound through the speakers.
