remote troubleshooting a D50 for someone else, could anyone tell me if with the USB input selected but the USB cable not connected to a computer, does the display say "Unlocked"? Or is that only for opt & coax inputs? thanks!
It shows 'Unlocked" with USB connected or not connected to host (Raspberry Pi), it shows "locked" whenever host has output.remote troubleshooting a D50 for someone else, could anyone tell me if with the USB input selected but the USB cable not connected to a computer, does the display say "Unlocked"?

Ah. We see the same issue as the Topping DX7s with increased distortion from -40 to -20 level. I continue to suspect that this is due to distortion mitigation feature of this ESS DAC. Hopefully Topping gives us a way to turn that on and off so that we can see if that is the cause or not.
it's possible to bypass that value. The value is called thb_enb in their datasheet and default to true. Possible to turn it to false by an updated firmware.Ah.

I forgot we now have the spec for the chip. Seems like those registers need to be specifically configured for the design and it is possible as you say, people are not doing that. Shame there is no performance data in the datasheet.it's possible to bypass that value. The value is called thb_enb in their datasheet and default to true.

But I doubt if it's the cause. by default, the thd_comp_c2 and thd_comp_c3 values are 0, and the thb_enb shouldn't have any effect. unless topping mess up with these values, thb_enb shouldn't take any effect even enabled..

Will drivers version 4.43 be uploaded to the Topping homepage?About a month ago, in response to my request, the topping's support service provided new drivers version 4.43. Subjectively, for me, sound with its much better than with the official 4.14. Nobody asked such a request, did not have more recent drivers? I would not want to disturb them too often.
No. "But unfortunately, we believe that V4.14 has better stability on low configuration PC, so we do not plan to publish V4.43 to the public. "Will drivers version 4.43 be uploaded to the Topping homepage?
Perhaps upload the 4.43 somewhere (mediafire/etc) if someone here is interested to try?No. "But unfortunately, we believe that V4.14 has better stability on low configuration PC, so we do not plan to publish V4.43 to the public. "
Do you still have it? Would be interesting to see if they turn off the Compensation in that FW. Perhaps @amirm can spare some time for another measurement of the device?No. "But unfortunately, we believe that V4.14 has better stability on low configuration PC, so we do not plan to publish V4.43 to the public. "
Of course.Do you still have it?
Even if they are the same, why would you need to though? The Dx7s got its own 4.14 update firmware here: http://en.tpdz.net/wdzn_detail/newsId=82.htmlHas anyone tried this 4,14 version with the DX7s ? I think they use the same driver as D50.
I am using Windows 7 Pro and just don't want to mess up perfect working system.

Drivers match byte by byte.I think they use the same driver as D50.
Is 4.34 still better then 4.14 version better sounding or am looking for trouble?
Do you say that v4.43 generate too noise in DSD playback?I have already tested V4.43, but it is not good to generate noise in DSD ASIO(Native) playback.
