I'd be looking at MUCH more inexpensive solutions. Take a look at the Schiit lineup of DACs, I think you'll find something from them that works quite well for reasonable money...

DAC question
I'm in a process of building my sound system. Currently it consists of B&W Matrix 803 S2 and Luxman M600-A amp. The next step is to get a DAC. I'm thinking about Luxman DA-06 or Aqua La Scala Mk II but not sure if it's really make sense to pay such money for DAC when using in such system. All my music is in flac (or other lossless formats)...
