This was mentioned earlier in this thread, and in the forum, but I thought I'd post a link here, because it may be of interest in this topic.
I have one of these being delivered today. I plan on trying it with a Bluesound Node and a pair of Ohm Walsh 1000's, which are also on order. My current system consists of McIntosh preamp, Bryston 4B3 amp, and Maggie 3.7i's, and analog & digital sources. The new stuff will be a secondary system, but it will be an interesting comparison.
