Been looking at the ALO Rx, the IBasso D10 orD4.  Like those sizes when paired with my iPod Classic, and find the Mustang and Predator too small in their geometry.  So--any advice on a great amp to supplement the UM3X??

I have the ALO Rx and it paired very nicely with the UM3Xs. Soundstage opened up, everything became clearer and the sound quality just improved across the board.

Can you hear the Alo rx noise floor with the um3x?

If I was using the LO and the song itself didn't have any noise on the floor, it was dead silent. I stopped using MP3s all together because I found those files had more hiss than the FLAC versions.
