Re: QMX(+) Build experience, Poor Audio Filter Sweep/RF Filter Sweep/Image Sweep/ADC IQ test and resolution with new PCM1804

 

It's remarkable that you have had three PCM1804 failures even while using antistatic procedures. I built a QMX and a QMX+ without using any precautions, and did not have a chip failure. The PCM1804 mystery continues.
