Yes. Sure..I’d like to purchase an additional DAC now as a »stand-alone« device.
Would you folks recommend the Topping E50 in this case?
Thanks a lot!

i reconnect back both the optical and coaxial inputs and do the manual switching, both are working now :=)a 1m or shorter regular RCA cable should work fine, I've had issues with longer ones.
If you have a video RCA cable (with a yellow connector typically), those are 75 ohm too and work just as well.
Yes, but it doesn't switch automatically to the live input. You'll have to switch to the input by pressing the multifunction touch button at the front, or left/right on the remote.

That would mean to stop trusting my ears.If you love music and audio QUALITY, then forget mqa FOREVER !
Your ears can't even decide if this toy says "brainstorm" or "green needle":That would mean to stop trusting my ears.
Power issue?I have E50 but after some times it turns off . When I try to turn it on again it automatically turn it self off again in a second or so
thanks for the advice for it is workingIf it is powered by the USB bus of a PC USB, available power could be too low for the E50 to work properly. Have you tried a separate 5V/1A power supply?
Hearing a difference is easy unless you match the output volumes exactly using a multimeter.I just bought the E50 and it's an improvement over the original Khadas ToneBoard. I didn't think I'd be able to hear the difference between the two?
Thanks, I will try doing thatHearing a difference is easy unless you match the output volumes exactly using a multimeter.
I can get a set of Presonus e3.5 monitors that have a TRS balanced input, so I guess that would work then!No, the coaxial is an input only. What other input connectors are on your studio monitors?
If possible, you want the RCA or TRS from the E50 going straight into the monitors (active I assume). The signal going out of the E50 this way is exceptional quality.
What can cause this sample to sample variation?Based on Amir's review, I purchased an E50 with an eye toward using it as the signal source with an E1DA Cosmos Scaler, ADCiso, and APU (in some cases). Unfortunately, I'm not getting the same results as Amir got. Primarily, the 3rd harmonic of the 1000 Hz tone is much higher than what he published. Mine is about 10 dB worse; around -123 dBc under the same conditions as Amir tested. The other harmonics measure very close to his results. Same for the noise level.
To verify the rest of the test system, I measured a D10s. My results were almost exactly what he got.
I also tried using the APU to notch the 1000 Hz fundamental. Same high 3rd harmonic.
Finally, I used a "Victor" test generator, which has outstanding harmonic performance. This really convinced me that the spectrum analysis part of the system is running as it should.
So, it's the E50.
My question is: Does anybody know how to tweak the distortion cancellation coefficients in the ESS ADC chip inside the E50 to minimize distortion? Has somebody figured out how to access those?
Thanks!
