This is an old thread but for what it’s worth, here is what I found with BL 8000s. I initially had them connected using RCA from my TV’s variable output jack to line-in. No pops. I later added a BL 2 to the mix to improve the bass. To do this, I made a stereo jack to Powerlink and then connected the BL 8000s to the BL 2s using PowerLink. I now have occasional pops. I believe it is caused by the Powerlink connection. I am using a Furman Power Conditioner and also the power cables were upgraded with Shunyata Venom 14 cables.
In my case the pops are irritating but I can tolerate them for now.
