Yep - I feel exactly the same. I had the Mojo for a few days and to be honest. If I didn't have the micro, I would have bought it right away, but if you already have the micro - update to FW 5.1 and enjoy it, mojo doesn't add that much in comparison. The micro is still one of the best value item I have bought in my audiophile journey so far.
