I have 2 cd players, which is better musically

I have a home theater system and a 2 channel. My 2 channel consists of:

Conrad Johnson MF 2100 amp, California Audio Labs DX-1 CD player, Acurus LS 11 preamp and a pair of 2Ce Vandersteen speakers.

Now I've been out of the audio scene for a while (as you can tell by my set up) and I'd like to purchas a new cd player - I think. Before I do I would like to swap out the DX-1 for my home theater setup which has a Denon 2910 to see if chaning the CD player is the right move or not. But its a difficult swap do due to the physical location and a major PIA, so if I choose to do the swap I just want it to be worth the effort. So basically is the DX-1 better or worse musically than the Denon 2910?
