I have an ARC LS5 MKII pre amplifier and have had great success with the EMC 1. I am not familiar with the Audio Aero player but I would think it would be wise to attempt an in home trial with both players to see which one fits your systems sound goals the best.
I love the EMC's ability to bloom. The newest version with the passive parts upgrade is world class in it's ability to capture decay and heft. There is no hint of digititus whatsoever and organic clarity is in abundance. If your pre amplifier has balanced connections you are in for some great mojo. The EMC 1 loves balanced connections and rewards you with a notch better quality on all fronts.
Good luck but make sure you can try it in your home. That is a lot of cake to spend without listening.
