Sd cards work fine if formatted correctly and used properly. I also haven't tried a 64gb yet but it's not spec'd for that. I also don't buy a player like this for MP3s and my FLAC and WAV files work fine. I do understand that it's a bit quirky and am not debating that. All I'm saying is that it's idiosyncrasies are acknowledged and well known.
You don't hear btn which is rather noticeable if not a major change and you don't appreciate it's sound in general so these quirks that you thought would be worth the effort, assuming you read these threads as described, no longer are. This player was never for you but you purchased anyway.
Did you check the return policy of the vendor before purchase? That's his fault? Write it off and once you know it's working properly, sell it off. We all do it all the time for things that don't meet our expectations. There is no problem with not liking it. It's this need to assign blame to everyone else that's bothersome. Bury everybody if you don't get your way. Others get a better shake etc. Your's is likely exactly like many happy owner's unit and your Vendor's return policy probably easily researched. Personally, mine's not going anywhere but I completely understand how it's not for everyone.
