Your options basically are to find a really good multi-disk player (there are some out there but they are very hard to find) OR punch out and get an outboard DAC. Here your options are several. Depending on the money you wish to spend, there are recommendations all over the place. I've actually got two different setups that would work that I need to get rid of but neither of these may fit your demands. Your first decision is whether or not you wish to keep the player you have and go with the outboard DAC. Good Luck.
