Then I misunderstood, sorry. It just seemed to me that you were very agitated when writing your posts. You did something like SHOUTING which in my experience is far from optimal
. Thing is we can´t see each other and us humans suck at interaction without seeing the individual we communicate with. Irony, a joke, those things might get lost in writing. So sorry for misunderstanding.
How do you access your music? I use 'Albums' only. I have tried 'Genre' and 'Artist' only once, hated it and went happily back to 'Album' (it´s how I listen anyway). From the little experience I gained using the 'Genre' & 'Artist' I concluded that every album needs to be tagged properly in order to be accessed without problems. I don´t know Musicbee, but just like you I use mp3tag a lot. Though I´ve already found that its tags sometimes produce errors. The programs I use most of the time are dBpoweramp and foobar2000. Reason: mp3tag cannot handle .wav tagging which I need.
On the other hand, maybe tags aren´t terribly important. I updated tags once on an album that was already on the SDcard of the X3, already scanned and in its databank. Updating the tags didn´t change anything, even after re-scanning the library. So I assumed that the FiiO doesn´t use tags when accessing the files (at least not when using 'Album' mode) and that it at first simply uses the file structure of the storage medium to organize; tags might be read only the moment the file is played back. To me, this isn´t very disturbing - as I said, 'Album' mode has been working very well. IMO, it even fits the 'retro' design of the X3. But then again, to me, convenience never was key. Or otherwise I´d have bought an Apple thingy.
I think - and this is a shot in the dark - that FiiO keeps internal priorities. They need to earn some money in order to develop new gadgets and to keep their business afloat, including their workforce. The first thing they wanted to do - obviously - was to enable the DAC feature. While I don´t need it myself, it still makes perfect sense: they needed to be on the same level of the AK 100 in order to stay competitive. In every magazine I´ve read, the X3 and the AK100 are pitted against each other. So when iRiver added the DAC feature, FiiO fasttracked that and held other problems and their solutions back. As they have now added that function they
might concentrate on other things. Regarding the X5: if I´d be FiiO I would of course develop them both together; assuming that they both use the same basic hardware setup (which I assume them to do). Secondly, they can´t promise anything since they don´t know what they might be capable of. See below.
Apple needed four to five engineering 'gods' to get the first iPod released (and it took them 3 years to make it Windows compatible... and why? Because they only knew their own Apple OS). And they had some 100 people working on the hardware alone. Add some other 100 people working on the software. Apple threw an awful amount of money and people at their first iPod. Then they employed people testing their new gadget. Lots of people. Lots of times. And all the while Steve Jobs was complaining that they should change the DAC (true story, he chose the DAC for the first iPod himself after listening tests). This costs money, loads of it. Money FiiO doesn´t have since they are much, much smaller. IMO it´s a wonder that they even managed to get this far, releasing a player of their own. And I´m not blowing sugar up their ass.
Apple can afford to use the fastest SoCs available. FiiO cannot, the companies producing the best SoCs won´t even talk to FiiO (they wouldn´t buy enough). But even then they afforded themselves the luxury of hiring firmware engineers. Compare that to other boutique manufacturers like iBasso who´re still trying to turn sh** into chocolate.
Yes, FiiO lacks experience. But I expect nothing else, in fact I was certain that it would be like this before I even bought it. They are still learning how to do stuff (you can only buy so much expertise... and who knows who holds some dubious patent for this or that) and believe me... they are blazingly fast. And their support still reacts friendly even when they are bombed with emails always asking for the same things (as I did). So far, FiiO has been an exception... and stupid Americans like you and stupid Germans like me can actually learn something from them: how to react to customers for example.
Maybe you could in the meantime try to circumvent your problem by trying to navigate via the album or file view. Not the most comfortable way, but it might get the work done and make you happy. I hope I´m not too naive here.
EDIT: Crap, sorry for writing so much. Typical for me.
