New L3 firmware in beta testing right now, I will release it once the testers say it is fine. Changeblog: 1. Added DSD album art support. 2. Improved USB DAC compatibility. Now it also support 32Khz sampling rate. 3. Added AIFF format support, and also album art support of AIFF files. 4. Improved compatibility with certain micro-sd card, fix rare playback noise bug with certain memory cards. I was told that playlist was suppose to come with this firmware, but some last minute bugs was found so it is pushed to the next firmware.
