I got to check out the HAP-Z1ES and its li'l brother at the 2014 Axpona. I was quite impressed, but I wasn't in the market for something like that at the time. Upon thinking about your post, I realize I really ought to consider buying this or a similar model for my setup in Taiwan. My 2-channel system is a good 40' away from my computer, so I stream Mac Mini music content via my Squeezebox Touch, which is great until either my computer or the LMS updates and I have to figure out what the heck just happened. I could avoid that with a a player/streamer.
Once you get your music player set up, post your impressions here or in the discless circle. I'm interested in your thoughts and reactions.
