Thanks for your input and concern but I've already sent a DX50 in once for refund. The second one sent to me was even more problematic then the first. I've since moved on to the AK120 due to all the card scanning and player lock up problems I was experiencing and what I now want is a refund not an exchange. I'm tired of all the back and forth with iBasso and just want to be free of the problems I've experienced. When I originally asked for the refund I asked if I should pull the battery like I did when I sent in my original unit for refund and they indicated not to bother and send the unit back whole. I now highly doubt that after all that's been said between me and iBasso they ever will agree to refund me. As it is, I've grown quite tired of them and their refund/exchange practices as well as wasting evening after evening trying to troubleshoot a player that refuses to completely scan my card or even run 90 minutes before locking up and forcing me to restart it. I'm now stuck with a 240 dollar paper weight because of all this. Live and learn I guess. Originally I wasn't going to say anything and I've kept an eye on this thread only in order to keep tabs on a new FW update that hopefully will solve my card scanning/player freezing problems. I only voiced my experience so others know what can happen. In hindsight, I should have never bought the DX50. All I'm trying to say with my last post and this post is if you have any troubles with your DX50 don't waste any time trying to troubleshoot it but instead send it back immediately.
Carry on friends, don't mind me and my bad luck. Maybe down the road a future FW update will fix my card scanning and player lock up problems. Crazier things have happened after all.
