The ZxR, at least on paper, takes the crown from the ASUS Xonar ST(X) for best SnR in class. The Z might be best of the bunch though, as with a 120dB SnR @ $99, gives the vaunted ASUS Xonar D1/DX a run for its money as king of the sub $100 price point.
Waiting on reviews, but these are clearly a major upgrade from the Recon3D lineup. I'll defer judgement until I see the full spec sheet (ASIO support, OpenAL HW Acceleration, etc]
