I'm too late on canceling the shipment of Aune B1. Should I just try it or just return it?
Problem is, even after searching I cannot find the rated output impedance of Aune B1 for you. For a normal size headphone this wouldn't matter 'as much'. When dealing with SE846 at 9ohms and a crossover the amp/sources output impedance plays a big role in how they'll sound, high output impedance can really screw up the sound. For example, 10ohm pair of Dunu DN-1000 plugged into JDS C421 with about 8-10ohm output impedance sounds completely hollow like someone sucked out the mids completely. So we can't even tell you if its worth trying. I guess the next step would be contacting Aune via email, see if they'll tell you, it would need to be very low to be completely pure with SE846.
Chinese site reports the output impedance to be 10 ohms? I'm not sure which gain and current settings it was tested at, or maybe they just copied the stat from the T1.

Anyway looking at the m8 teardown, seems like it has a good amp section but uses qualcomm's built in dac, which isn't really good. Ideally amp + dac like the C5D @~$250, I would return it.
