Fosi Audio's First Dual-Mode Balanced Amplifier ZA3

Quantifying a pop with a qualitative word can be problematic. What I consider loud you may consider minor.

Luckily you can test it for yourself. Leave the amp on. Unplug it from the wall. Then plug it back in and listen as you do.

Has anyone figured out what the input impedances are for the RCA and XLR inputs? For some reason, I can't find this anywhere. There are a few posts in this thread of people asking, but nobody has been able to respond with an answer.

He guys, if read this entire chat, but i'm still wondering if i should remove unused op amps. I'm using 2 za3 in mono and XLR. I removed the Left op amp and replaced the right op amp and XLR for sparkoss Lab ss3602. After reading this I was planning to also remove the sub op amps. Its not doing any damage to play with empty op amps sockets?

I can't speak to whether it made any audible difference or not, but I can confirm that I ran my ZA3s in mono mode for about a year with the left channel and subwoofer opamps removed with no issues.
