I'm considering pairing my Airmotiv 4's with an Audioengine D1 dac. I use the airmotivs with my macbook pro for lossless audio listening and some 320k mp3 listening. The speakers sit on my desk nearfield (2ft). I know the D1 is highly regarded, but at least one review has described the sound from it as more "fat" and rounded than lean. See link below. Since the airmotivs are already very neutral and lean, I'm wondering if this would be a good pairing or just muddy up the clarity of the airmotivs a bit. Anyone tried this combination out there? I really like the airmotivs, but I do miss some of the midbass from my old audioengine A5's that made guitars sound so nice.
