For example, you use software on a PC or Mac to tag/rip, not the player. Let a specialist handle that instead of a mere player ![]()
Your last requirement (to me at least) is somewhat akin to finding a purple unicorn. I've yet to see something that's a true DAC/Headphone AMP as such, other than the normal ability to successfully plug in headphones <shrug>. In any case, $699 is kind of steep for such a device IMNSHO.
FWIW, my iPhone and iPad both can play back my tagged FLAC files w/ VLC and some other apps as well.
I think the max frequency that matters, (48k max I've heard.) Replaceable batteries and microSD storage are already things I know I need. No radio tuner is nescessary. It also must be able to have awsome tagging abilities so I can add great detail to my music (File management software). Good playlist software as well & Ripping capabilities as well (I want it to be able to play ANY music format I throw at it.) a touch screen is nice but not required however a hi-res display screen IS. It also needs to function as a DAC/Headphone AMP. The FiiO X7 is what I am thinking of as a possibility. I know those are alot of expectations but the closest things you can think of would be much welcome!
