I found some time to play with REW today with a view to trying the moving mic measurement technique. However, when I started doing to some test sweeps, I noticed that right channel on my Topping D50s appears to be broken. Here's what I see in REW (Blue is right speaker driven by right channel, brown is right speaker driven by left channel)...
As you can see, the output takes a nosedive after 6Khz. I repeated the test with the left speaker and I got similar results. After some further investigation, I found the right channel would pop and go silent when a test tone hit 6,154Hz pretty consistently. It's as if the right channel turns itself off when it reaches this frequency.
I have noticed the odd pop when using my system over the past few days, however i've also been playing with Voicemeeter and some VSTs, so I had dismissed this as a consequence of my semi-competent fumbling with the windows audio pipeline.
Does anyone have any thoughts on what the problem could be and if it would be fixable? I purchased the DAC in August 2019 from ShenzenAudio via Aliexpress, so my chances of getting it back to China are pretty slim.
