Audio Aero Prima DAC

If you can't find one used, then you may wish to check out the audiomeca enkianthus X dac. It uses the same anagram chipset, and it is very, very nice. Just something to consider, as the prima dacs used are very scarce.

I had an interesting sensation in my ears/head whenever I first got my Audiomeca Enkianthus XD dac (uses the same chipset as the AA Prima Dac) especially whenever I had it out of phase. The sensation only occurred at the start of a listening session and quit after a couple of days to a week. I am almost certain the sensation came from my ears "getting used to" the MASSIVE soundstage that the Audiomeca throws.

Think of watching a TV show in 3D. At first, you may be slightly disorriented by adjusting to the 3d, just as a few people may have a similar sensation when getting a new, very high performance piece of audio equipment.

I don't know if this is what you have experienced, but I know the sensation went away after a couple of days. My audiomeca Enkianthus X Dac was the second best audio purchase I have EVER made.
