I finally received mine and am up and running with an AudioQuest Dragonfly Red, but am pretty disappointed so far with the sound. Almost no bass or midbass.... Nice top end sparkle and clarity, but literally zero bass. Still tinkering, hopefully they burn in and get better.
I had a chance to try them over the weekend off of my desktop setup: Schiit Audio Bitfrost Multibit DAC and Valhalla 2 amp. Obviously much more power than the Dragonfly Red, but still the same result. No bass/midbass whatsoever. I was forced to use software EQ to boost the bass to a level that wasn't completely overpowered by the mid and upper range.
Anyone else having a different experience with the Nova? I'll give them another week of trial, then they are being sold..
