Excellent Head-Fi'er, instant payment. Thank you! - Aumkar

Unfortunately, we have no plans for any revision to the CAL.1H.

I had purchased this when the Empyreans were launched, have never used it. It's just sitting in it's box since the last few years. Condition is excellent and essentially brand new. I'm in the process of moving into a new facility and most of my collection is packed away in boxes. This is one...
