Elect. EMC-1 Mk II vs. Audio Aero Capitole Mk II ?

I'm considering buying one of these CD players based upon previous recommendations online here. Between these two players, can anyone further recommend which sounds better and what the differences are in sound? I will be hooking it up to a Conrad Johnson MF2500A amp and two B&W matrix 802 main speakers. I also have an Audio Research LS-15 pre-amp if I need to use. I'm aware the AA Capitole has a built-in pre-amp. Thanks again
