First off, you have a great CD player! I really enjoyed owning a stock Opus and then later, a modified Opus before switching to an Apple Laptop and, now finally, a Mac Mini.
I used a Cal Audio CD 5-disc changer connected to the RCA S/PDIF input on the back of the Opus with great results. I couldn't tell the difference between a disc in the Cal audio and a disc in the Opus, which speaks to the proper implentation of the digital input.
If you have a Mac tower, or a Windows desktop, you can buy a sound card that has a S/PDIF RCA output, which you can connect to your Opus with a RCA terminated digital cable in order to play the hi-rez 96 kHz/24 bit files. If you have a laptop or a Mac mini for instance, you'll have to buy an external device to convert USB or F/W to a S/PDIF.
I think Steve @ Empirical Audio might be able to help you with such a device.
