Why 2 analog outputs on jolida jd100?

What is the purpose of two analog outputs on this cd player?

If I connect one set to the cd inputs on my preamp, and the other set to the aux inputs on my preamp with a different brand of ICs, could I compare the the two ICs by just switching the source knob on the preamp?

I posted this on AA but am not getting the info I need!
One for each foot??? I would say you have one option down. Another would be one to a 2ch pre; the other to a HT. receiver.
Also can use one output to drive a pre and one to drive a headphone amp; that's what I do w/ the 2 on my EMC-1UP
