Pros: sound details, staging
Cons: no auto mute at start
I am really fond of this DAC, thanks to it the whole musical scene is depicted in great detail, especially for the higher frequencies.
Bass could be improved .. I really prefer the bass of my Arcam Black box 5
The bass/lower mid is less precise and it's hard to "see" where it comes from, again, in comparison to Arcam Black Box 5.
I'm always listening through the optical input, cause the USB input is not as good as the optical one.
The headphone output is really usefull, too.
Volume knob is only usefull for the headphones, does not apply to the line out.
Multiple inputs (USB, spdif, toslink, bnc) are great too.
Maybe the usage of options is little tricky, and the manual is available only in Chinese ..
Great product, however.
