Nope.

I'm pretty sure he was telling you to install the stock firmware before the releasing of the improved sound for the 1A, so you can remember how the stock sound was and then see how the custom firmware evolved that sound or something.

Exactly as this will exemplify just how far the CFW has grown from the origin as the difference is now indeed significant...

Q-6

Want to try this and see how this improve the sound.

I think, that won't work as when both plugs are connected, balanced takes priority. The 3.5 SE is shut down. No sound comes fom 3.5

Yep, the 3.5 just act like the grounding.

This is your 1Z persoanlly modded?

It’s mine

I don't have any cables with outer shielding to test but didn't Sony decide not to connect ground due to added noise. There is provision on the board that they chose not to connect, nothing complicated. I bet that adapter costs a small fortune

The adapter will be listed 13,200 Japanese Yen. Which around 125 USD.

I wouldn’t do this mod chances are you would get DC offset issues or worse a power surge would permanently damage your headphones or your ears!

I needn't tell you how increasingly invasive the world around is becoming. Not just the authorities. When one wishes to remain untraceable, one needs to purchase only those devices that can't be tracked. Especially those in media and journalism and even those normal folks who might turn whistleblowers for the good of all. Surely good audiophile devices aren't only for those who lead normal lives? One can discard a dozen phones a year while on the run but one needs to be super rich to discard a high-end DAP every 6 months. Hence the search for a private DAP but of at least 1A/1Z league.

even they can trace the DAP, how do they know who own it.

With a shielded cable all this would do would extend chasis ground from the WM1 around the 4 headphone signal cables up to the headphone but not connect to anything at the headphone end. It's just chasis ground around your shielded headphone cable.

It’s not a question of whether or not it can be done. The circuit IC is configured in a certain way. It’s not a breadboard where you conduct experiments on and “see what happens). Also there is a chance of bricking the DAC. There’s a plethora of things that can go wrong but I guess if it’s your R & D money and player at stake, go for it!

An even more fundamental question is what do you gain from putting these outputs in?? Do you even know??

Does the next mod have an impact on battery life?

It shouldn't, but it remains to be seen.

Lol I didn't propose doing it but your commenting on the least risky mod ever of adding ground to the pentaconn but miss the the mod to right of a removed relay, dremmel cut circuit board and large power cap.



And I beg to differ, I take it you haven't got to the WM1A/Z Mods thread started by @Whitigir its been nothing but a breadboard of experiments.

Then maybe you should present your mod suggestions there for feedback for such experimentation.
