I got my D12 today and I'm extremely happy with it! I get a lot more detail out of my music, and it feels stronger and more refined.
The only critique I could give is the lack of a manual. Even on their website you can't find a whole lot of information.
I would especially like a bit more information concerning the opamp rolling. I see I got one from Analog Devices and then two chips who seem to be bypassed by a diode.
Am I correct to state that the gain switch should be up for higher impedant headphones?
Edited a stupid fault.
