1) The difference between poorly recorded (or low bit-rate MP3s) and well recorded songs will be quite noticable with the SM64.
2) What headphones are you comparing the SM64 against? Comparing to my Westone W4 the SM64 actually has more sub-bass and the mids are more forward.
3) Just spent a few minutes listening to the SM64 directly out of my HTC One and it could be described much like your smoothed out road analogy. Turning the Beats audio on helped some, but mid piano notes were still sounded quite off. Maybe the HTC is the weak link? Have you tried using a computer with the E17 and SM64? That would be: Computer > USB cable > E17 > SM64. Use some of your FLAC files. How do they sound then?
4) With a USB OTG cable (Lindy 31717 should work) your HTC One can send the bits directly to the DAC section of the E17 (which is likely better than the DAC inside the HTC One). Not the best write-up but this guy really likes the result he gets: http://gavinsgadgets.wordpress.com/2013/04/07/htc-one-daily-blog/
Thanks for your reply :)
1) I don't listen to any poorly recorded or low bit-rate mp3s. Everything is either 320kbps or flac.
2) I was comparing the sub-bass to the other two that I have the H-200 and FXZ-200. I am very much aware that the SM64 has more bass than W4. It's just that when I listen to bass heavy music, I like to have that sub-bass rumble like the FXZ200 has.
3) I don't think I would ever use Beats audio unless I was using the speaker. There's just something I can't trust about it. The thing about connecting the computer is, there would never be a situation where I would do that because I only listen to music during commute. Well I do listen to music sitting in front of the computer but through my speakers. I think I'm just being too picky.
4) Yes, I use a OTG cable to connect the E17 but after the last firmware update on the HTC One it got weird. The One recognizes that something is connected but the audio out through usb sometimes works, sometimes it doesn't. Sometimes it recognizes it and then plays from the speaker which is quite annoying so I've been using 3.5 for now. I remember talking to the guy from gavinsgadgets long time ago before I got the one hehe :)
