Received this player just today and what took me by surprise at first was that it didn't recognize either of my 32 GB and 64 GB Sandisk Ultra cards, taken directly from a Fiio X1 and a Fiio X5 II. When I would mount them onto the player, it does not even see them inserted, which was strange! I then proceeded to use a Sandisk Class 4 32 GB mSD card and it managed to recognize that, thank goodness. My firmware version is 1.10. I haven't updated that yet. Should I? Do updates expand the library of mSD cards recognized by the player?
Does anyone here use Ultra cards and have them not seen by the player, also?
Now for initial sound quality impressions. I've very impressed with it paired with the Phillips Fidelio L2s. Clarity is an improvement compared even to the Fiio X5 II, which was a nice surprise. Then again, I think that player sounds a tad muddled compared to other players I've owned.
I'm a bit worried why my Ultra cards are not read by the player, whatsoever. I'm also somewhat disappointed that there's no alphabetical search functionality like Fiio players. Sonically-wise, though, I'm more than satisfied.
I think nothink is wrong with yourd cards, same hapend to mo with a sandisk used in a Fiio X3 mark 3. You have to reformat the cards as out of the box, raw, and then insert in Sony and format there. There are many tools for that, for the moment i dont know what ive used, as i sont have access to my laptop
