Thank you Gonk. So it would seem that for me to play SACD's I would need to use the Oppo analog outputs to connect to the 990. In which case if I wanted to improve the musical sound I would still need to upgrade to the SE. I read a lot of posts and have come to the conclusion that for cd's or two channel sources the SE is the way to go. Also from what I read the multichannel improvement is not as dramatic. This might not be the proper forum to ask this question, but if your were interested in very good 5 channel SACD audio would you upgrade to the SE?
