1000+ Head-Fier
I've upgraded from the OnePlus One, I would say the its slightly better in all respects but on the audio side of things the 10 is big upgrade.
I do have the Audio Technica Msr7 so I can test them with the HTC 10. I would say that will be a great pairing, the Msr7's get the best out of everything I've plugged them in to.
I can't test the combo until Monday as they are my office headphone, but I can say now they definitely won't require an amp as the Msr7 is a very easy headphone to drive.
I just purchased the HTC 10, will test it with K3003 and SE846 IEMs and Momentum Wireless over ear headphones taking advantage of both devices being Aptx!
Edit: add to that Mojo and HiFiMan Edition X...
