Thoughts on UPnP after a year with the Uniti

1. Windows. Asset UPnP works very well with great functionality, including album artwork, Apple Lossless (converted to WAV on the fly ?). Tried others such as Twonky, Allegro but no Lossless support. Asset also functions smoothly via iPhone Apps such as Plug Player or PS Audio Tag n’ Play
2. Apple Mac. Only Eye Connect works well for me. Great at streaming direct to the Uniti where Album / track details are shown on the Uniti display. Also streams Apple Lossless. However, if I want to use PlugPlayer or PS Audio Tag n’ Play then I cannot stream Apple Lossless or WAV– the Uniti tells me the "file format is unsupported". No album artwork either.
3. Uniti – I found it be very router sensitive. The higher spec Thomson router that I upgraded to with O2 had continual dropouts (also with iRadio  but only on BBC stations !) and whenever I switched from UPnP to another input and then back to UPnP, it was unable to find the server. Only solution was to reboot. Switching to the bog standard POS router that came with my original O2 package solved all the problems. Strange !
4. Conclusion. Windows users are well served (!) with Asset UpNp. Apple users are also OK with Eye Connect although it is a pity there is no album artwork support and I still don’t understand why it won’t play my Apple Lossless / WAV files via Plug Player.

Overall, I believe that UPnP still has a “work in progress” label attached to it.

For sheer user convenience and hassle free operation my current preference is the Apple Remote /iTunes / Airport Express combo. Works every time with Mac or PC, marvellous convenience & functionality and, to my ears at least, no discernible difference in sound quality.
