I've tried Sony Vegas, Premiere/Premiere CC, Pinnacle Studios, some "free" video editing softwares and all of those have lag or stutter issues with the live playback EXCEPT PowerDirector. PD was the only software that edited 100% lag and stutter free with my hardware for my GH4's 4K files. 
My Specs: i7-3820 @ 3.6mhz, 16gb DDR3 1600mhz Ram, 1070 SC 8gb, 120gb Corsair Nuetron GTX SSD
But the weird this is, all the software lags with ANY resolution video I used, even 144p stutters and lags with all the settings configured to try and help video playback / smoothness. I have a feel something NVIDIA Control Panel is overwriting a setting cause the lag in most of these software. I'm just glad PowerDirector works amazing, but lacks some features Premiere has. So it maybe your software rather than hardware you may need to change?

We are in the same boat then cause mine is fine with that cable into my camera as well. And it is fine with a battery and XLR to XLR in my amp, but not having the battery in it wont work. Even wiggling the cables to get some type of ugly sounding feedback wouldn't work, even messing with the filter switch while doing that didn't do anything at max gain. So, its either a button or setting on the receiving end, or the mics have some fault with it. Assuming all my brand new cables are perfectly fine. 

I only have access to another copy of the same exact amp I have, so I'll try that out when I can. 
I will open it up ASAP and check if anything is loose! I'm very good with working with soldering, hopefully it doesn't come to that, but if it does at least I found the issue to fix it.
Idk where to even begin to find a sound professional and figure it out. I'll try doing everything but that first, and yeah hopefully register it online if I can't figure it out! I just need it fixed the same day I begin investigating the problem.
