Kevin,
Just an idea but I have a 3-4 yr old Marantz CC4000SE 5 disc changer that is used for same purpose - bakcground and parties. It was the fastest deck on the market then with disc changes, drawer openings, disc payback time literally twice as fast as anything else. I found the Sonys to be slowest. The Marantz will change discs in 4 secs, so fast at social functions that one one ever notices a disc is being changed. I'll hit the 'shuffle' button and music starts in 5 seconds and discs change in this function in 4-5 seconds. However, if you are playing 5 discs in a row it only takes 4 secs between discs. This is about far better than the Sonys and Onkyos I tried.
