I have to agree with all the comments above. I was shocked at how good this little plastic DAC is sounding in my system! Other than playing playing FLACs, WAVs, AIFFs, etc. through it, I also stream Spotify through my MacBook Pro to it, and it really sounds musical and enjoyable. I love this little DAC. BTW, the cable that comes with it is absolutely crappy, so I use a Pangea 14SE with the C7 end on the DAC side.
