Audioengine D1

I've been doing a lot of shopping around for a good DAC/ Amp for some DT 770 pro's (250 ohms). I came across the Audioengine D1 and was wondering if anyone here could vouch for this. All the reviews I have found have been positive but one can never be too careful. 

-Thanks

It is good for the money. You can often times find the D1 on the head-fi for sale section for fairly cheap and in great condition.
