I've only just seen this site but all of you seem very intelligent so here's my question, and I'm sorry if you've already covered this. I'm putting together a home theater in a small room and my current gear is as follows. B&W 602 for fronts Polk bookshelf for backs and B&W center soon to be purchased. I'm running the b&w's off and old onkyo stereo reciever but am looking at the surround Denons and Marantzes in the $500 range because I don't play really loud (more concerned with accurate sound). Now to throw a wrench in the works my friend moved and gave me his Magneplanar SMGa's. Are there any surround receivers in the 500 dollar range that won't mind mixing 4 and 8 ohm speakers? I'll probably get a sub too which will take even more stress off the reciever. Or should I keep the maggies as a music only setup with my old stereo onkyo which they sound fantastic with anyway? I appreciate any thoughts on the subject
