So early testing suggests this device has a lot more punch than an iPod, and a smoother and less fatiguing high end.
Having said that, file management is a little awkward so far, in that I can drag and drop WAV files from my hard drive, but tracks are then saved and played in alphabetical order.
If any of you have more experience with the HiFiMan players and file management please let me know.
In the meantime, I am going to add sequential numbers to the beginning of tracknames to create playlists, and keep an iPod for less critical listening.
