You pop in asking for advice and some was given rather quickly based on what details you provided. Then you blow a gasket and 'wash your hands of it' over a relatively minor task. Many, many users are enjoying the X5 problem free from day one, and most (if not all) problems have been user error or card related. Also, a lot of people would agree its worth it.
Whatever, you have your gauge for tolerances and that's fine. Good luck.
Edit: Apologies, bad day. Hope you find what suits you.
I certainly hope I am not stuck with an unusable device now that my Amazon return period has expired.
As you eventually realized, the tf card WAS formatted in the X5 and the problem persists, so simply reformatting the card and reloading my library is NOT the solution. I did it again last night to be sure, and now MOST ALL of my 96khz and 192khz files "stutter".
Note: I've had this X5 for over a month now and it worked flawlessly up until a few days ago when it started this absurd stuttering effect. I have added NO new files to the TF card in at least a week -- IE: days before the problem surfaced. FiiO, please offer a solution!!!
PS: if it seems I don't have a lot of patience for these problems, it has a lot to do with the fact that I bought an X3 at Christmas and had a terrible experience with it and FiiO support told me to return it as defective. This, however, was only suggested after weeks of back-and-forth trying to pin the blame on other problems, like card formatting, firmware, or bad files, etc. so -- no -- I don't have much patience for this new problem that has spontaneously developed on what was up to now a great device.
So FiiO, it's up to you now to tell me why this is happening and offer a solution. Thank you.
as a new adopter of portable source gear, with the X5 (my only other purchase is a Sansa Clip Zip} I am concerned about this issue. Although my cards were initially formatted to fat 32 in my linux computer with Gparted partitioning software. I had zero issues with stuttering, file skips, tags, album art etc. My files are all flac and a few aiff. There must be a reason why these files would play pefectly for weeks before starting to exhibit stuttering. Although my problem was cured by a re-format in the machine. When I play these files I'm still holding my breath, waiting for the problem to re-appear. I'm not about to abandon my Fiio, but I'm not sure we have the final answer to this issue.
