As someone who plays exclusively hard drive based music, I personally wouldn't consider a product like this for the following reasons, cost aside for a minute (note that this is highly personal and probably does not apply to most people, this is just for general discussion).
In order:
1 - Loss of transparent digital EQ functionality prior to D/A conversion (via PureMusic or Amarra) that allows me to level out unavoidable axial room modes and achieve a +/- 3dB flat response up to 150Hz in my listening room.
2 - Loss of the extremely powerful iTunes library management functionality, given my huge and dynamic music library (smart playlists, powerful tagging, artwork, playback statistics, iPhone/iPad app, apple IR remote, view options, general flexibility).
3 - I use only a single source so am fortunate that I do not need to introduce a preamp into the playback chain, this module would be overkill and would mean additional input/output stages and an analogue volume control in the signal path.
4 - I prefer to have spinning hard drives out of my listening room (although I expect the 111 to be inaudible in this regard, or perhaps they will go full out with dual SSD for $50k).
5 - Flexibility of the NAS unit (automatic backups, accessible from several computers, complete control of the data, this might be the case with the 111 I am not sure).
6 - Ok, and then there is the cost, I could buy 3 additional 911's for this kind of money (or 1 and a whole host of improvements in other areas).
Just my 2 pesos, when I read over this list I realize that these points are probably not considerations for most people, and see how it is a great all in one solution and can be extremely desirable.
The Burmester product I would love to see most is a reference level DAC (i.e. 069 module) designed for power amp direct use with volume control (like the 099 but reference level).
