I was listening to AK120 playing some dsd album the whole day. I'm very impressed! Too bad the battery burns twice as fast as playing pcm track.. I think I only got around 5-6 hours with almost full charge. I really wish it can go to 8-9 hours, it would be a perfect companion during travel and office hours.
What is the battery life with flac/wav? A list mixed with 16 / 24 bit, average.
