I completed a long weekend home demo with the UD-701N last week...
so impressed with what I heard (as was my wife) that I went ahead and asked my dealer to order one for me on Tuesday and picked it up yesterday (very fast turnaround).
It's now residing in my system rather comfortably. Very nice piece of equipment and I feel a great value (as is the NT-505X).
BTW, I'm not real thrilled with the Lumin/TEAC/Esoteric app, but it's usable. Mconnect is still my go to for control, but that may change if/when I ever do more streaming (other than my local NAS).
Although nothing beats a home demo, this thread here was very useful (and just a few others I found in the interwebs). Lots of other usual suspects in this price range for Streamer/DACS, but this TEAC fully suits my needs.
