Mabonn - I have good results with MacMini -> Airport Express -> short glass Toslink -> Benchmark DAC1.
Two possible problems for you would be limitation to 16/44.1 and loss of lock between songs (nature of Airport Express). Some DACs are sensitive to loss of digital stream during gaps (Benchmark is fine) but it can be remedied by elimination of gaps by crossfade in Itunes.
In addition, AFAIK Apple express receives data in ALAC format. I also store data in the same format to save space and to avoid conversion.
During installation of such devices you might be asked question if you want Apple Express to "join existing network" or start new network - you want to join existing network. Ideal would be to have 802.11n wireless since 2GHz is polluted by a lot of devices including microvawe ovens. My microwave oven operates at the same frequency as on of the wireless channels and I had to select different channel. Now it works without any dropouts or problems.
Apple TV is perhaps a better choice while price is about the same.
