Preview: IMR Acoustics R1 Zenith

I received the IMR R1 Zenith this past weekend, the bigger brother of the IMR R1. I really enjoyed the original and have incredibly high hopes for the 2nd iteration, the Zenith.  These are currently available IMR R1 Zenith

I am giving these a little time to season with some white noise and FLAC files. More to come…
