Yes, I've been using an Airport Express for streaming for a few years, both the original 811g and now the 811n models. I leave the EQ off completely and the electronic volume control all the way up.
I had a few problems with the earlier 811g getting interference from a 2.4 Ghz cordless phone and a microwave but solved that by switching channels within the AE. The 811n has never had any problem with interference.
I've used three different DAC's with them and never had a problem with signal locking.
I use a glass Toslink cable and mostly Apple Lossless files plus some high bit rate mp3 files. The setup sounds great and is very easy to use.
