Fully appreciate the one box approach and is a good solution for the number of CDs you own. If I remember correctly your Sony has Burr Brown DACs in them which were very popular and good sounding DAC.
I concur with other to look toward an Esoteric of some flavor and would add to listen to one with an AKM AK4497 DAC chips in it. While there are other factors such as analog output stage design and transport that will have an impact on sound, my Linn streamer with their Katalyst DAC is based on the same chipset and it is simply the best DAC/Analog output stage I have heard or owned.
Also - this could be your exit market investment in CD playback. Worth a purchase if you will get the use out of it.
