And You have to get UK adress, otherwise it won't work. Just got one for a friend, thanks.

Should work for addresses outside UK as well, that’s how I got my 1Z

This may sound like a whole boat load of BS. But since firmware 2.0 the audio quality out of WM1Z by Digital output is improved. Now it is superior to Dx200 Coax. Blacker background with more air and details in it. It still can not help to go any higher into the Bandwidth of Input Signal on my DAC in comparison to Dx200. The Coax on Dx200 could go very high in BW while the WM1Z doesn’t go that high. Though the Digital output performances is now better than Dx200 + latest firmware.

This could be the firmware on Dx200, and when I have the time, I will downgrade the firmware on Dx200 and compare again.

But for the conclusion ATM, I am super duper happy with WM1Z on Firmware 2.0

1/ improved analog signature out of 4.4mm into Utopia
2/ improved Digital Audio Quality as a transportation into my Desktop System for my 009 Stax
3/ provides AptX HD which I am super happy with as well.

Now Dx200 is behind in all counts in comparisons....amazing !!

Sony, Jobs well done ! This is now a real Flagship :D

Something came into my mind that Sony now has the ability to control all 3 things

1/ S-Master
2/ Walkman OS system
3/ Sony propriety IC chips

Now, Sony can fully control and tune the sound signature just by the firmware....crazy Sony ! But I Like It

Another advantage of this full control due to them being vertically intergrated company - they can optimize battery life to full potential! With dsp effects off and playing 320kbps mp3s, I'm getting 32hrs of battery life, and if I have a mix of mp3/FLAC files, closer to 30hrs.

I only have 16/44 flac and get about 20 hours playtime and a weeks stand by (never turn it off) with a battery managed full charge so I usually charge every Sunday

I did this test with display off, continuous playback after verifying full charge:

w/FLACs, 4.4mm HO, DSP effects on - 19hrs
w/MP3s, 4.4mm HO, DSP effects off - 32hrs

Seems that enabling DSEE HX and DC Phase Linearizer drains battery faster, and also noticed DSD will drain it faster as well.

I use direct source and bluetooth and nfc disabled but do a bit of browsing to find the albums I want to listen. All on low gain balanced driving JH13. A full weeks use between charges with my use pattern is fully acceptable.

This sounds about right

Also playing USB digital transportation also drains it faster as well

I've noticed that DSD 2.8 MHz gets noticably less battery life, bringing it into range of normal MP3 players and phones. I cant say for certain, but dsd 2.8 runs about 5600kbps, 96khz flac runs about 4600kbps. From the above estimate of 19 hrs at FLAC, looking at 15 for DSD, which I would have to guess is right on, if possibly even a generous estimate from my usage. Does anyone know the exact CPU architecture and specs of this player?


**Edit**

I’m at 137 hours playtime on mine. I just realized that I most always have been using the 2.5mm headphone jack, and is it true that DSD out of this is conveted to lpcm? (increasing cpu cycles to convert)

Not only does MP3 playback save battery life, they sound pretty darn good from the WM1Z.

Last night I could not distinguish between 24/96 and 320kbps?

1Z ------MP3 nirvana.............
