What are the specifications of the D1 DAC/AMP? What are its output, impedance , etc?

Darkrai10 ohm output impedance for the amp. Gain is very high though, measured 20db.
The amp is not intended for sensitive headphones/IEM , but rather for medium impedance, medium sensitivity/efficiency headphones.
Let me know if you need more info, I got one right here.

LQDForceSo given the choice of the 80 or 250 ohm DT 770 would recommend the 80 ohm?
I guess it comes down to the fact it's a USB powered amp, so it's not got the power available to drive higher impedance optimally?
I'm new to audiophilia, so I'm just checking I understand things correctly.

neuneuThe D1 will power both of them just fine.
If you want to understand output impedance and impedance in general, read NwAvGuy's excellent article here: http://nwavguy.blogspot.co.il/2011/02/headphone-amp-impedance.html
Anyway, The 80 Ohm DT770 is the better option in my opinion, not only because of it matching the D1 , but because it sounds a bit different than the 250 Ohm model. More bassy, punchy and a tiny bit darker/less bright.

neuneu@neuneu I use one of these with the DT770/80 and it sounds great! This should be sufficient to drive either the 80 or the 250 ohm. I auditioned both the 80 and 250 with the D1 and greatly preferred the bassier sound of the 80.

kenliuThat's exactly my observation as well! The 80 Ohm model is bassier and more punchy.
