Review and Measurements of Topping DX3Pro DAC and Headphone Amp

[kukocz]

Those switching supplies actually inject mains noise. Using USB power is good in the way it reduces the number of power supplies in the system. I would not mess with another supply.

But DX3 pro cannot be powered from usb, therefore this is wondering whether better power supply can improve quality or not.

Oh sorry, I thought we were talking about another product. Never mind.

My advice remains though. There is no reason for a different power supply.

My Topping DX3 Pro got stuck in standby mode today. It stopped outputting sound completely.

Have you done factory reset?

In my two DX3 Pro, twice occurred the phenomenon that no sound was output to RCA when turning on the power again after turning off the power with the USB connection.
It did not recover even if factory reset was executed.
Withdrawing the power cable unavoidably and recovering it if left for about 1 hour.

Abnormal operation may occur depending on the timing of turning off or sleeping this product.
I am experiencing a similar phenomenon in DX7s.

Yeah, the factory reset(display 8-8) doesn't help. When I reset the DX3, it won't power off, but goes into standby mode again.

That way is wrong.
Since I posted the method of factory reset in the past, please look.

Thank you for the link, but the lights don't respond when I turn the knob counterclock wise 3-4 turns on my unit.

Turn the knob counterclockwise until all the display's indicators are lit.
Expressing the number of turns is difficult! !

Ah, I got it! But the DX3 remains stubbornly in standby mode

Yes, I predicted the result.
I propose to unplug the power cable and leave it for about an hour (maybe even more). It completely discharges to eliminate the abnormal memory inside.

I uped the troubles that occurred in my DX3 Pro before.
please refer.

I am sorry, I am not good at English. It is a strange sentence.

Don't worry! I appreciate the help

Okay, I unplugged the power cable thrice for an hour and it didn't work. I've contacted the vendor on AliExpress about the issue and hope to hear back soon.

I hope everyone enjoys their unit, cause mine will surely be missed.

It's strange behavior of this device, once right during playback, it went into stand-by mode and I already thought it broke, but when I clicked on the knob, it turned on. So far this is not repeated.

If computer recognizes the DAC, maybe you can try to re-flash the unit? The only thing I'm wondering about is that I'm not sure if it is doable when you have already the newest firmware onboard. But you can try...

I think that I am also really a strange machine.
Even if an error occurs, operation will return to normal if various operations are performed.
D50 DX7s also places a strange phenomenon.

It is not related to the firmware version. The same trouble occurred before updating and after updating.

I believe he's stating to try reflashing the firmware to clear the unit of any errors, like a full factory reset.

How do you set foobar in order to read the Dsf file extensions of Dsd?

How do you set foobar in order to read the Dsf file extensions of Dsd?

I wish I knew. I followed Topping's instructions and installed components. Then changed output from WASAPI to Asio.
Tried playing the file, it exploded with full blust of speaker, when I turned down the sound nothing played.

Ended up, converting the files to 24/88.2 FLAC, using foobar settings of double check with 30kHz filter. The gain is probably - 6db, but amping output automatically can lead to clipping.

Do we have any experts on the dsf, sacd, dsd64 playback and conversion?
