Personally I would do a CD HU from the same era (like the DRX9255 in the classifieds or that Nak above, P9, etc) analog to a DSP and then use a Phone/DAP or other USB source to one of the digital inputs on the DSP.

My wife! Before anyone gets bent out of shape. My wife is as golden as golden is! She would laugh her a** off at my comment! She likes joking around, I love her for that , been together for 30+ years and married since 2003.
