Well, I got my DX50 today. Simply gorgeous, taking it out of the box. And after, of course! I ordered from MP4 Nation, so I got the R3 headphones, but I'm not sure when I'll spare the patience of trying those. Kind of finicky, but some people seem to love them.
The sound of the player though. Wow. It just sounds magical. The music seems to flow effortlessly from this baby. Makes you feel one with the music.
Going to write down a list of the small bugs and issues I notice. Nothing major or even close to it, but I'm sure it'll help iBasso make the UI even more perfect.
Just a quick note to anyone who is still hesitating to buy this. Stop! Don't wait one more minute. If you can spare the money, then just get it. It is an amazing deal for the price, even if it costs several hundred more.
