mdrew- to playing the sacd's properly, you have to ensure that you have the cd/dvd player hooked to the receiver using the 6 analog connections. plus, when playing the sacd, you have to set the receiver to play the 'analog' or 'mulit-channel' input.. if you did this, then i am sorry for implying that you didnt.
in addition, i think to really get the full sacd experince, you need the full 5.1 set-up. unless it is a 2ch sacd, and i havent heard any of those myself. if you were playing a 5.1 sacd just thru your M80's and sub on the bottom floor, then you would be missing out on 3 channels of music(center and 2 surrounds).
