Nothing too terrible. For me the wishlist is: 1. Gapless is still not quite right. (That will come I am sure. It took a while but they got it working rather well on the PAW Gold.) 2. One of the best features of the firmware is that whatever you select to play (for example an album) automatically becomes the current "Playing List" which can be added to, deleted from and resorted. (It is like Rockbox this way.) But the sorting is messy: you drag and drop a song and it lands kind of randomly. Sometimes I move a song three times before it sits where I want it. This should be easy to fix and I hope that they do soon. You will be very happy. If you find the sound to be a bit too neutral (a matter of taste), try the PMEQ setting in my signature. Anyway enjoy. This is a fine DAP.
