Well, I decided to give the player a chance. These are very early impressions based on limited usage. I haven't tried to connect to WiFi so I have no comment on that aspect.
The UI is pretty snappy, especially given the limited RAM. The display is pretty good too. There isn't much in the way of apps on the device, but at least it has an internet browser. Since you have to sideload everything, a tool to make this easier would have been helpful.
So far, I seem to be free of any annoying clicks or pops, using forgiving 32 ohm moderate sensitivity IEM's.
I'm not thrilled with the sound so far. Maybe it needs some more break in. The sound is too laid back, compared to my Shanling M3, and even my Sansa Clip Plus. It makes for a fatigue free listening experience, but it isn't very involving. Soundstage is average at best, and so is instrument separation. I guess the word I'm looking for is congested. The treble presentation in particular is lacking. It seems rolled off and lacking in definition and detail. The player has a mid forward sound to me with bass, while present, that lacks impact.
I can't see me using this device over my alternatives, unless the sound improves significantly. I expected a lot of glitches and issues, and so far I don't have any. But I expected the sound quality to be better than it is. To my ears, it just doesn't sound like a high end device or even mid range. It seems to take the life and emotion out of the music.
It does get very warm. After an hour or so the metal caps aren't just warm, they're hot, again with simply playing from a card. I would imagine streaming or Internet browsing might make it worse. Hopefully it reaches a maximum temperature of what I'm experiencing and doesn't get any hotter. The unit makes a small click when powering down, no big deal.
