Hello, mate! I'm using WM1A right now and using WM1Z sig with higher gain "1" option.

I've read a bit in the forum that I should NOT turn the high gain mode on the PLAYER so I can use the higher gain "1" in the settings file, is that correct?
Even if I have to use higher volume step?

Also, did someone make a measurement about how high is the "higher" gain?

Thanks in advance.

So, I have done some measurements on my WM1A.
All measurements were done with Walkman One firmware (Walkman_One_J123_(07_03).zip) with Bright signature.
The player was in DAC mode, the signal from its balanced output was routed through a 47 Ohm load to the input of the PreSonus Audiobox 22VSL audio interface.

I checked the effect of DC Phase Linearizer settings on the player's output frequency response, and compared the output frequency response for a few regions.

The results of my measurements are on the attached pictures.

Nice work!

Looking at the "regions" - it's all the same

There are even MQA files packed in 16 bit FLAC files. MQA seems to be for more than just having high frequency data packed, but also about analysing the file, and then processing it in a way so it will be used with a certain filter (out of many possible with MQA) when "unfolding".

Yes, you can get these 16-bit files from MQA-CD (mqa cd｜Search｜HMV&BOOKS online [English Site])

That's strange because the same SD Card with MQA files was recognized by the Sony ZX-507.

How do I confirm if it has the correct tags?

If you have Foobar, you can check the files' properties

I'm not sure if the "ORIGINAL SAMPLERATE" is actually used.

It was because I tried to manually change the "ORIGINAL SAMPLERATE" to some weird number, e.g. 99999999. The walkman can still play the file w/o any issues (and it displays the weird number as its sampling rate).

Sounds wise, seems no difference to me.

I kind of remember that it still works fine even the rate was set to zero.

Probably someone can try negative value too. Ha ha...

curious to see what differences there are between normal dac and alternate dac mode, also curious about dsee hx killing the top end of every song. i dont think regions will show much data because it has more to do with instrument placement/seperation. maybe regions dont actually do anything and we're all just desperate hahahah

Regions absolutely 1000% do something. I guess it's like the cable arguement that if it doesn't show on graph apparently it doesn't make a difference.

This is very interesting.
I didn't have a lot of time for this, so I made some test measurements to see how the frequency response changes when changing the settings.
At the moment I have the stock firmware 3.01 installed and didn't have time to keep changing regions.
I decided to check how vinyl imitation settings affect the output signal of the player.
In the attached files are the graphs obtained during measurements, you will understand what to what according to the legend.

For measurements I used REW application. Output signal is 96 kHz. The player as a DAC.
The output signal was taken from the balanced output through a nice thick copper interblock cable.
As an input channel I used PreSonus Audiobox 22VSL audio interface input.
I'm not an expert in such measurements and electronics, maybe I did something wrong, maybe I made the connection incorrectly. But during the measurements I had a very fast battery drain on the player, and when I switched on simultaneous charging with the player while using it as a DAC, the player got very hot and the warning indicator (mark on the battery) started blinking and I had to stop the measurements.

When I have more time I'll try taking measurements on the Walkman One firmware with different regions.

Thank you so much for your great works on these, really helpful. I'm saving these for references, hat off and big applause to you!

I'm glad my efforts were useful to someone. In the future, I am going to continue my measurements. Unfortunately at the moment I am busy with work, I have to work on weekends, sometimes at night, so it is difficult to find free time for this.

Exactly. Although it is not reflected in the frequency response, but small differences are noticeable in the phase graph. I have not yet figured out how to interpret such information. Maybe it's all at the level of measurement error. I have attached phase graphs for different regions and for comparison phase graphs of different DC Phase Linearizer settings.

Can you check j3 too? that seems to be the best region, plus the most advanced one

If the frequency response shows a difference, I would check all regions. I checked a few of the most popular ones and did not see any difference and stopped there.

Hi Vandammmmma.
The short version is that getting high gain through the Walkman One, will be one way of adjusting it. Getting it from the player fw. is another way! But if you turn on both, there will be some sort of cancellation! So it's one or the other! The more technical explanation will be for others here to explain, it out of my league!
