So I decided to just get a 4K UHD BLu ray player as my media player, it plays everything even SA-CD discs, an so I was browsing the SA-CD's available, and I came across one that I really would like to give a listen, Alice Cooper's Muscle of Love, only thing is it's a Quad release, I've never heard of a CD being a 4 speaker release I assume? How do you output to 4 speakers for a stereo system? Or does it just somehow play normally on a 2 speaker setup? Or if not how does this work? It's an Audio Fidelity release, and I've noticed there are other Quad releases, and I must admit I don't know much about this, Thought I'd see if others knew about this. Thanks for any help with this.
