squeakath Now that I have had this DAC/Amp for more than a month, I would like to add to my first my impressions. My favorite headphones are Beyerdynamic DT 990 Pro's, rated at 250 ohms. The 250 ohms probably make a difference.
The amp pushes these headphones without any trouble at all. The highest volume that I can use comfortably is with the volume knob at 11 o'clock. With these headphones, there are no shrill notes, nothing to make you cringe.
Across the sound spectrum, this DAC/Amp sounds really good and balanced. Deep voices like Louis Armstrong's and Johnny Cash's sound great and tubas and bass drums have a lot of punch but don't overwhelm. A lot of detail always comes through. On the high end, sopranos come through clear and strong, although I think the lower end of the spectrum is represented a little better than the high end.
Paired with a Speakercraft BB275 amplifier and two Polk Audio Monitor 30 Series 2 speakers, the DAC sounds even better.
In summary, I enjoy listening to any type of music on my Daart Canary, with or without headphones. For the cost, this is a good choice for DAC/Amp.
