Hey, I was wondering if anyone can help me narrow down this one time issue I had. I plugged in my Hifiman Sundara headphones into the FiiO Q3 Dac/Amp which I received today. It was playing great for a while, but about 10 minutes in, randomly I was adjusting volume down and the left driver of my Sundara produced three very loud cracks, and I immediately turned off the amp and unplugged everything. I thought at first maybe the cable was at fault, but I checked the connections already with a multimeter and everything is fine. I also have been using this same 2.5mm balanced cable with the E1DA 9038S G3 for a week, no issues. I've been playing around with the volume to see if I could replicate it, so far nothing. Maybe it was a volume adjustment error? I know FiiO uses the ADC reconstructing curve to get perfect channel balance with an analog potentiometer on their Q series, perhaps that malfunctioned for a second? It's either the amp or the driver, but I guess I can't know for sure until I can replicate the issue.
Also maybe there are some tests I could perform to pinpoint the issue, suggestions?
