Finally, my red AP80 arrived today. It really is a tiny gagdet, almost as small as a matchbox.
Customs was cleared in Belgium, no fee, no declaration on the package either. I'm less impressed by Hidizs' packing standards: Both boxes with the AP80 itself and the one with the leather case were just flying around in a somewhat bigger package. No padding whatsoever.
Hardware
Hardware seems okay, the knob could be a tad tighter but it's not loose. Turning it I feel a little resistance, I like that. But it sticks out enough from the case to be easily pressed or turned unintentionally as others already pointed out. I don't like the silver edge of the knob. B/c nothing else aluminium on the player is silver (i.e. not colored red) it looks like wear and tear to me. The right (or lowest) button protrudes just a little less than the other two and thus is noticeable harder to push.
FW version is 1.0. The player works flawlessly with my new exfat formatted Sandisk 400 gb card. Copied some folders via my iMac (artist / album / file or artist / album / disc 1 / file).
Both screen protectors have been applied precisely w/o bubbles or dust. The silicone case is transparent dark grayish and really looks horrible on the red unit. The leather case is a bit too tight and takes some serious effort to be removed. Pushing the side buttons with the case is impossible for me. The leather case is meant to wear the AP80 on the arm band or a belt so (at least for me) it makes the tiny player too bulky with the strap and the press button. With none of these cases you could put the AP80 in your bag with other stuff b/c the display ist not protected in any way.
User interface
Display is very good though not cristal sharp. Responsiveness is okay for everyday use. There's a noticeable lag when loading album covers. But mine are mostly above 1000x1000 for other players, so the AP80 has to do some work.
Adjusting the volume from the shortcut menu is a real pain. Why on earth did they have to place the volume slider in the lower right corner?! It's just too small for me. No problem adjusting display brightness in the lower left corner.
Cosmetic criticism that could be solved through firmware update (if ever there will be one):
- album covers are reloaded each time I scroll through the artist view and only when fully visible on screen; also on the now playing list, sometime missing w/o scrolling
- tapping on the album cover in the artist-album view should start playing the album from the beginning, no need to navigate to the track list first
- no album title in main player screen
- would be nice to have the artist name (in gray?) as a second line in album view
- question mark in front of every genre
- adjusting volume with the knob only sometimes shows the blue "sugarloaf graphic"
The remote control on the 1More IEM is not working with the AP80. No volume adjusting or pausing/skipping.
Listening experience (quite subjective)
Sound quality (that's what I've been backing this thing for ;-] ). Listened with my 1More Triple Driver IEMs as I would be commuting with this combination. Quality ranging from VBR MP3s to FLAC 24/192 (though I won't notice the HQ difference on that train or else in my age ;-] ). Listening included Tori Amos, Simple Minds, Foghat, Gary Numan, Johnny Cash, AC/DC, Massive Attack, Yello... all "old" recordings, no remastered stuff.
First experience is quite good, I like the sound. No MSEB or otherwise fiddling with the equalizer.
Bass could be a little more present. Johnny Cash's guitar on American IV sounds a tad fuzzy. Massive Attack Angel's first minute sounds quite okay but I didn't expect the AP80-1More combination to be spectacular here :-]
Mostly I'm missing deeper frequencies with music that has noticeable piano and quitar parts. I liked Gary Numan's Splinter or Pop Levi or Simple Minds' Big Music a lot, though. Could be the player is more suitable for modern recording/mastering? Well, I will have to listen to a lot more music to come to a final verdict on this little guy.
Tried FM only shortly but I found a couple of stations, sound quality was good. No noticeably background noise w/o music during speech. No station identifiers, of course.
Listening experience (not so subjective)
Then I tried Art Blakey, Foghat and Stevie Ray Vaughan as DSD64 and Sophisticated Lady Jazz Quartet as DSD128. DSD64 files clearly have a hissing sound in the background during quiet moments that is not there with FLAC converted from the same SACD. And if you heard it once you will hear it always, definitely annoying. I can best describe it as waves on a distant beach. I didn't notice any hissing sounds at all with DSD128 but I only own this one jazz album in this absurd quality.
Didn't try anything bluetooth yet.
tl;dr
All in all the AP80 is a nice player with very good sound quality (FLAC/MP3), though (for me) it might lack the last 10-20% in quality especially in the lower frequencies and with guitar/piano parts. Not useable for me with DSD64 files. I will also have a look at the Fiio M6, though I'm not sure I like the size.
Regarding the more than questionable customer experience with Hidizs during the last months, I ken not recommend them as a company to people I like and I will not buy another Hidizs product (sorry, couldn't help myself, haha
).
