Now, compared with the dx228ex, is a rocket!!! On dx228ex I have to charge the battery daily for only 5 or 6 hours top.

I know!! But the power output and the performances to drive headphones though . Sony battery and it ability to keep going is mind blowing !!!! The majority of it is the Digital interfaces chip, which is so efficient and dedicated to music.

The dx228ex is a beast!!!A true demonstration of power.Sony is still rocks with his sound signature thought.He keeps his ground very nicely!

Lately I have use the 3.5 output on wm1a as line out on my desktop configuration.The advantage of Sony battery is keep the music going for days without any interference from the plug.So it can be use as a quality source dac.

When I tried that with dx229 beside I was ending without battery in a matter of hours,I get a different sound signature than Sony .
On wm1a I am getting better separation and I can hear layers in music with a better texture.All together a more relaxing sound.
And that with the ofc internal wires from the 3.5 side.With some occ or silver gold ones will be heaven...

I have Lotoo Paw Gold 2017, Questyle QP1R, and Sony NW-WM1A. I am very happy, but still lusting after the Sony NW-WM1Z.

What type of ac-adapter is safely recommended for charging the wm1a if one does not want to use a computer?

Apple chargers are pretty good at filtering noise and ripples.

I use my old "genuine M$ accessory" Zune AC adapter/charger. Just like the Zune itself, it's an overbuilt unbreakable brick.

If sony puts high current/voltage FETs on the amp sction to increase power, while sticking a 7400mAh battery like fiio. It would be a treat

Question on the battery on my 1Z
I have owned it for a little more than 2 years however quite honestly it has seen very little use (I have a number of toys here to play with ).

I have dusted it off and started using it in a bedside system however the battery life is now atrocious.
Can the battery be reset/calibrated ie running down to empty and then charged again? Should it be replaced - and if so what is the proceedure ? I am located in the States.

lets buy a huge external batery pack 25000 Mah and make our own DMP Z1-1A lol

So then what is the proceedure in the US for battery replacement? Is there a list of Sony service centers for the 1Z? Curious as to turn around time

PS actually found a Sony support article about battery life. Maybe my problem is the screen setting. It indicated that lowering screen brightness from 5 to 3 ( I assume 50% to 35%) dramatically increases battery life. Screen turnoffset to 30 seconds as well
