I just received my M a few days ago. It could replace my RWAK120, but it's not an easy decision... My wish list for the M
- place "song number / number of songs in album" between current playtime and duration of song
- when picking an artist do not show all albums in an expanded view. Add an option to the preferences for a "compressed" mode, in which only the list of albums is shown; tapping on an album unfolds the list of songs
- add an option to the preferences to let the user choose how a usb connection is treated; let's say, the M ran out of juice, you plug it in and boot it. Now you want to switch to USB DAC... you can't unless the battery has reached a certain level. The only way I know of to choose the usb connection type is to unplug and plug again, but the M will tell you that battery is too low and shut down automatically. Not good!
I guess that the points mentioned above are easy to solve via firmware upgrades. Do you know how to contact the folks at Calyx / Digital & Analog to highlight those wishes?
Oh and battery life... 3100mAh on the M vs 2350mAh on the AK120. The M plays almost 5h of ALAC with screen off, the AK120 more than 13h. My M does not get warm. Where does all the juice go to? I would assume that this energy has to be dissipated somewhere!
Edit: Interestingly, the Cayin N6 has even a bigger battery (5600mAh) and a similar performance as the M (5-6h). What kind of magic are the guys at AK/river doing to get so much playtime out of their devices?
