To be honest, I do most of my portable music listening (to albums, downloaded music, ripped music, etc) through a Pono. I mostly use the phone for internet radio (WFMU, my pick for the World's Greatest Radio Station...Happy World Radio Day, by the way...), occasionally stream through TIDAL with it, and I haven't sat and done the geeky back and forth A-B comparison stuff with them. It's more a gut thing, didn't like listening through M8 as much, felt the need to connect it to a DAC (but didn't succeed), enjoy listening through the HTC10, less nasties, more enjoyable, still use my Pono when I want to have better sounding portable music (but haven't done the A-B thing either; grab it when there isn't a show I really want to stream on. Balanced Pono, with the Pono being available for about $200 on sale at times, is just really nice sounding). So, there you have it.
