OK, here's a question: will a good quality SACD player connected to a preamp with stereo RCA cables only, have better sound that a standard CD player? If so, how does this compare to HDCD?

The reason I'm asking is because I have an average (well I would like to think above-average) surround sound setup mostly for watching movies. It's the family room and it gets a lot of use. I also have what I would consider a mid-fi 2-channel (stereo) setup that I am constantly upgrading. It's sort of my pet project. I would prefer moving our SACD player to that room so that I can use it with the higher quality seperates, but I would be giving up surround sound.

Any thoughts?
