I have seen the Sooloos demo'ed but have only played with it in the store. I previously had an Arcam FMJ server which was great in its day but not particularly user friendly. Once Arcam discontinued the model there was no support available when I had issues but still good for the price. I have had a Qsonix system for about 4 months now and love it. I run it through a Moon DAC. Have the 1.5 TB HD and 19" touch screen. The touch screen and the interface make it so easy to listen to all the CD's you have had for years and forgotten about. You can select by Cover art, artist, album and many others including year, decade and composer. You can make playlists based on current songs, moods, time of year, driving and hundreds of other combos. Can save playlists and transfer them to an Ipod or burn CD's. Can run it remotely from your listening chair with an Ipod touch or IPad. Gives you album reviews. I have mine hooked up to my home network so can also run it from any computer in the house. It is always connected to the internet so whenever there is a software update, it is automatically downloaded to your unit, no matter when you purchased it. There is no yearly maintenance fee for this. Have contacted support a couple of times with minor questions and had excellent service. Its not perfect but very close to it. Highly recommended. If Sooloos is better than this and it better be to justify the price differential, it must be great.
