Anyone know if this dac/amp would pair well with the SoundMagic HP100? I am a total n00b at this and I am quite not sure if the impedance would be a problem since the HP100 are at 32 ohms. Thx for the help!

It'll work. The D1 can drive headphones that are between 20 and 300ohms. I use it with the 63ohm Sony MDR-7506 and it works great. Basically, it'll work with any headphones you have unless you go out of your way to purchase very high impedance or very low impedance headphones.

@Charles @Jean-Pascal @nilayk @last_sd @Ka <br />As @Ka mentioned, Audioengine's own specs on the D1 rate the 3.5mm jack at a 10ohm output impedance -- the common rule of thumb is that the rated HP impedance should be a bare minimum 8 times the output impedance (according to some, 10 times or greater). See Sec.2 of Tyll's DT880 Trio article for some helpful analogies/explanation:<br />http://www.innerfidelity.com/content/comparison-beyerdynamic-dt-880-32-ohm-dt-880-250-ohm-and-dt-880-600-ohm-headphones<br />By that reasoning, the lowest HP impedance for pairing with that 3.5mm jack should be 80-100ohms (e.g. Beyerdynamic DT 1350). Don't know what that FAQ question/answer is doing there -- seems to try to skirt the issue by distracting with the opamp specs.
