HiHello dear folks, this is my first post here, so thanks for having me to everyone .
I own the Sr15 for 8 Weeks now and I simply love that DAP. I am coming from the Fiio X5 III and mostly changed to A&K due to the X5´s badly screwed up actual software.
Some people are worried about the SR15´s power, my experience till now is, yes .... the FiiO X5 III hast a LOT of more power and even turbo-mode, BUT the Sr15 delivers enough power for my headphones though:
I have the HD660s, running them at 65-105 (max!!!) and the Ultrasone Edition M Plus (55-85 max), both connected balanced, both sounding just perfect and still some resources available.
And the Sr15 again gives me that nice grin and thrill on old tracks, on which the X5 III did not after 2 years!
Battery drain of the Sr15: I came to my conclusion, that round about 10% of the battery get drained in 1 hr, which leads to 9-10 hrs batterytime when listening to SD-card-tracks without playing arround too much with device, very similar to the FiiO X5 III.
But I also have one big question, how do you know when the Sr15 is fully charged, when it is powered off ? On my device it shows a charging screen and the display shuts down after few seconds, but I am not able to turn the display on again by simply pressing the power button or any other button to check loading status like you might be used from other Daps like the FiiO. As the Sr15 has no quick-charge-ability (as far as I know) it would be very usefull to check that without having to start the device.
Regards,
Andreas
If you plug out the charge cable and plug it back in again when the device is off, the battery icon appears again with the charge level.
