Trolling

[f1eng]

I continue to view UPnP as a much simpler, more elegant and enjoyable solution and at least on par, sound quality wise, with Air.

I guess it is what one gets used to. As a music lover who was on an aeroplane most weeks I was delighted to swap my heavy case full of media for my portable player for an iPod with its weightless supply of music
This meant I became familiar with iTunes right at the beginning, and whilst it is far from perfect familiarity leads me to prefer it to everything else I have tried since.
When I experimented with streaming music at home one of the systems I tried (for about a week) was the Linn Klimax DS.
It was counter intuitive to me and the supplied ripNAS needed rebooting too often to be acceptable.
I gave up on it and went for a CD player with integral USB DAC (Resolution audio Cantata) which sounded better and was much more convenient for me to use.

So my experience, and therefore opinion, is the exact opposite of yours. If Devialet added some sort of UPnP functionality I would probably not even try it...
