Despite the positive experience others have had with Aurender products, they should be avoided like the plague by the astute consumer for a number of reasons which I don't think I would be allowed by the forum moderators to elaborate on here.
Also, while the products may have streaming as a function, the architecture is very much a server. If Aurender wanted to market music streamers then they should have thought about what having a full blown OS, storage, and a glorified FTP server would get them.
To those who enjoy them - my sincere message is to find something different, there are plenty of alternatives which not only perform better, but are easier to deal with and offer a more flexible solution for just about any system. The people and product you are supporting has done and still does absolutely nothing to actually benefit the realm of performance audio, despite what the press and the internet have tried to reinforce for you.
My suggestion to the OP would be to build a Raspberry Pi and run Snakeoil OS, with the money saved you can hold onto it and either purchase a proper streamer/DAC combo (which have a lot of technical advantages, and most outperform something like an Aurender) or eventually a better DAC and music server/streamer configuration. Heck, with something decent you might actually be able to share music between rooms, something which Aurender has never been able to do for some odd reason....
