Unless you have paid for a tweaked out Mac, chances are your computer server is a snore for digital playback excitement. Move your music to a Synology NAS and get an Auralic Aries streamer... you are just not providing the source needed to hear what your DAC can do. And oh yeah... the Aries can feed coax to your DAC or you can use the Audiophilleo you have if you prefer it.
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)...
