I know this sounds silly, but I am looking to have an "adult" system and a "kids" system. Unfortunately, I do not have a separate room for what will be my system so I have to have the family room as my playground as well as my teenage daughters. What I would like to do is have a receiver and CD player for them and the same(except much better) system for me. I don't want them messing with my stuff but I don't have room for two separate sets of speakers. Is it possible to play either receiver through the same set of speakers? I know I could probably get a A/B speaker switch of some kind but won't that degrade the sound. Is there one available of audiophile quality? Or is there another alternative?
