So how well does the AudioGD Compass Drive the HD600? Just wondering how it sound

When I had a pair, it drove them fine, but not great. With most music I could enjoy listening, but a few tracks, such as a live recording which has a very wide soundstage, it sounded more like you were behind the audience than in the middle. The new Fun (in A-mode) does a better job with higher impedance cans IMO.
