I had a couple of problems using folders, so I decided not to use them. Maybe part of the issue is that they have accurate rip files and other stuff like jpg's and all that kind of "stuff" that ends up in the file along with the music.
It seems "picky". It plays best if I put the .flac files, and only the flac files (have not tried mp3, for me why bother).
It sounds really great, but I really don't have any really high quality equipment to compare it to. Maybe I should not compare it to anything because ignorance will be bliss.
I love the sound, it sounds better than my Marantz 67se and it is much easier to carry around.
What a great sounding player.
I did note above that I took the battery out to reboot the HiFiMAN.
That battery is fing huge! It must eat a lot of volts/watts or whatever, but again It sounds great to me.
I am a very happy customer, even with the couple of bugs I have run into.
I do not plan to play 24 bits throught my HiFiMAN because I don't think I have 24bit ears. At my age, I think I have 16bit at best.
Anyway, it powers my Senn 555hd and I can't wait until I try it with the Senn 600hd's.
Now if the kids can get their homework done, I can to some real listening.
This is my 2 cents for what it's worth.
