Curiosity got the better of me and I now have the X-DACV8. Although it needs to "break-in" fully, I can comment as to how it compares to the A5. The tonality is similiar but the X-DAC V8 is noticeably more robust/extended in the bass/lively, a bit smoother and probably slightly warmer, yet also more resolution. Definitely worth giving a listen to if you are looking for new dac.
