A CDP can make a world of difference to the sound of your system. I have been through a few CDPs since I bought my first years ago. Each one brought a new diminsion to the sound. More information, better presentation, better overall performance. had it not, I would still have my first one. But with advances in clocking, D/A conversion, laser technology, transports, the list goes on. You have a good system and the basis to hear the differences. Pick out your budget and start researching which player you want.
