It's as you said it man....
Plus : I am still using files like the rest of you instead of streaming
It's more than obvious that the quality of downloaded files its way above the streaming quality... Everybody knows that, and in addition to this, this quality is what you eventually hear during playback.
So.... Instead of downloading Lurker's update its more important to use flac/wave music files... IT'S THAT SIMPLE!!!
Furthermore, why bothering and experimenting with different firmwares, when anyone who is serious at this hobby, can tell you that the most crucial (by far) factor in the playback quality is the earphone earphone itself!!!!
That's IT..... PERIOD
Sure the player plays its part there and the dap implementation as well, but not the most important believe me....
THE earphone makes the big difference..
All of these of course when speaking of sound quality alone
And that is what matters the most IMHO always, the sound quality during the playback...... If you have a good earphone.. do not bother with anything else man...
It's just neat picking stuff......
My one & only complain with DX160 would be the battery life.. But I can live with that.... Since the SQ is great combined with a good earphone...
