There's an albums by artist feature coming in the firmware to be released this month. FW2.14beta has it:
Two known bugs of the 2.14beta:
-Max volume is low (volume had been remapped into 120 steps, but only the first 60 steps are available)
-the menu items for "idle power off" and "sleep" have been mixed up, so you need to set "idle poweroff" to "off" to prevent the player from shutting down (sleeping) in the middle of playing a song.
This user-made mod addresses the volume issue.
Thanks for the reply, Joe. I have read back about thirty pages in this thread, so I was aware of some of these fixes, though I was a bit confused. I thought that the current FW would look like the pictures posted earlier by JamesFiio, but I gather that's the yet-to-release version.
Having read many reviews and watched videos, as well as searching for FW version change listings, I was aware of all the issues I'm having, and bought the player to evaluate whether they made the X3 too tough to live with (I like the DX50, but doubt its 3+ ohm output impedance would suit my 10-ohm Dunu DN-1000s.) If it is, I may return it and wait to move up to an X5 or DX90, if iBasso isn't misstating its OI, as they seem to have with the DX50. Either way, I'm glad the new FW will be out soon!
BTW, the current volume is already WAY more than I need with IEMs. : )
