I picked up my 1124 today. My usage will be a lot different than most people's I'm sure. I'm using it mostly as a streamer for stereo listening. It has all of the services I want, DSD playback, DLNA, and a pair of pre outs for my powered speakers. I won't be using it with a TV or with movies. I might add some surround speakers at some point but for now it is strictly stereo.
Plugged an Ethernet cable in and turned it on. I could use airplay immediately as well as Spotify. The DNLA feature was seamless as well. Once I started JRemote and told it to play to the 1124 it mostly worked. Had some weirdness with JRiver I had to figure out. My one ongoing issue is that the 1124 doesn't seem to like playing 192/24 files. I only have one album but it refuses to play it.
I also was a bit disappointed with the iPad app. It works well enough for the super basic stuff but it lacks a couple of big things. First off I had to hook the receiver to a TV in order to set the speaker size to large and tell it I don't have a subwoofer. That was a pain. I was also shocked at how ugly the on screen menus and graphic are. Glad I won't be seeing them... I can use the app with a DLNA server but it is pretty clunky, better to use another app like JRemote, it's much easier to use.
The sound is very good. To be honest I haven't noticed much difference between this and the 24/192 DAC that I had been using. What I've gotten is a lot more functionality and convenience. Good stuff. Now if only some company would sell the same thing without all the power amps I'd be happy, lol.
I'm mostly done with the features I think. I might go in and set up some Internet radio stations but for right now I'm enjoying my own library
