DMP is 10 hours on FLAC as estimated by Sony. It doesn’t have quick charge, so it would need 4 hours for full charge. However, it can run on AC plugged in even without any battery inside
, and this is different than charging while draining the battery away from many other devices. This is one other marvelous design from DMP. It is so marvelous that if you can build yourself an Ultra high-end Low Noises Power Supply externally, you can continuously be using DMP from AC itself
Streaming suck....why would you want to buy something of this caliber and be using streaming ? WiFi interferences, App algorithms suck....file quality also suck. If you are dedicated enough to buy DMP, you are dedicated enough to buy CD and rip it properly, and perhap you would never accept anything less.
