I would not use FLAC if you are going to run Mac. Use the Mac's version which is ALAC. Furthermore, iTunes is not limited to 16/44, but the AE or Apple TV may be. If you run PC, do not use iTunes at all, but some other player such as J River. With a Mac, you will get better sound using a different player as well, but the integration of iTunes with Mac is hard to beat. There are better players that use the iTunes database (Pure Music, Amarra)
FWIW, it do not trust wireless, moreover as thee previous poster stated, the direct connections are better. You are not indicating what DAC you will use or what type of comp (PC/Mac). I think your best bet would be to use an iPad to control a Mac mini that is directly connected to your DAC, preferably with a good wired connection.
Nice system and beautiful home BTW.
