Well I've just purchased a 2nd hand Ibasso DX50 and I have to say, it's simply a stunning player.
The audio quality is 2nd to no player I have ever owned to date (I'll confess that goes back to the Sony Walkman days too fellow audio fans).
Stunning sound reproduction and the equaliser is terrific to boot. There's really no complaints with the playback on this player at all.
When I first received the unit I performed a firmware upgrade and havn't experienced any major issues.
One however was that while out jogging, the player seemed to switch itself off, then upon switching it on again, it performed a system repair and then all was good. I also noticed a tendancy to jump tracks randomly, however the lock switch fixed all these issues for me.
I'm trying out different headphones and I notice that my Sennheiser PMX80's required a lot less volume output than say my Superlux HD681's(higher impedance no doubt). I'm looking forward to trying this player out on several other models of headphones on there way to my doorstep later on.
So far my only gripe would be that with all the firmware revisions it still looks to have glitches and I do wish the screen could be set to always on for when your at home listening instead of winking out and having to press the power button once when you want to view it. Other than this, it truly is a top of the line player.
I notice some people declaring it ugly? Can't understand that, it's got a nice metal case finish, it's easy to navigate(oh on that, the scrolling system requires one side to have more space to actually scroll as it's too easy to bump a track when your in the middle of listening to something), it's sleek and stylish in my view.
My only case issue would be that I wish all 3 jacks were located at the top of the unit with the SD card slot at the bottom or in the side of the unit. Other than that, I can't fault it.
Amazing player. 8/10
One last thing, does anyone know a good site for downloading high definition audio albums? Performing a search for 192KHz on HDTracks for example yields just 4 tracks. Where are 192KHz high definition files to be found? Most HD Tracks seem to be stuck at 24bit 48KHz, which is a real shame when you have the capability of playing uncompressed audio up to full 192KHz capability.
