I am a bit disappointed with this little device. It doesn't sound terrible by any means and is quite well put together for the price. Refreshingly, the local distributor doesn't impose the dreaded "Australian Tax" as another plus. However, I can't find a use for it in my system. If anything the gain is too much for my ATH-AD700's and I just cannot detect any sound improvement over the headphone socket on my old Acer laptop with either iTunes or high definition flacs from Linn with the Audio Technicas. My AKG Q702's sound flat and lifeless through the D3. Arguably, even my old Sound Blaster HD external sound card does a slightly better job of driving the 702's but both pale against the Lead LA100 which is my go to box for computer audio currently - admittedly twice the price but still reasonable for audio gear. So I'm still lookin' for a truly portable solution for my 702's.
