The 3a/16 demo at can jam, while not perfect, was pretty jaw dropping in two areas:
1) transient impact and bass punch.
2) actual soundstage with focus and crazy imaging
The bass hit your chest like a jackhammer, and overall the sound was really impactful. It reminded me of a nice k1000 setup in that regard. To hear soundstaging from an IEM where it was layered in front and around you, with incredibly precise focus and clarity, was pretty remarkable.
There might have been some weird midrange funkiness, and I am not quite sure whether they have all their DSP stuff all figured out, but I think there is good Eason to believe it will be a quality product.
