I think you answered your own question by mentioning you have a connector that, when you jiggle/move it, you get static
Replace that sucka and move on. Actually, youd better check the other one as well, and probably replace them both w/ better HQ components if I were you
When it comes to recording cables/mic cables/etc, if you dont have the knowledge/precision to do it yourself, spend the $$ on a set of SUPER HQ cables that someone here on ts.com can make you and be done w/ it forever. You may not want to spend the $$ on a pair of cables, but IMO cables are just as important as any other component in your recording setup IMO. If a cable fails on you, you are SCREWED. So dont forget to seek out HQ cabling and you'll NEVER have to worry about that probllem again
I have ALWAYS bought HQ cabl;es for my recording rig, and they have yet to screw me over in ANY WAY
I even started out w/ Audio Magix X-Streams XLR's when I bought my AKG 481's and my Graham Patten DMIC-20 back in the summer of 1999. Ever since I have kept along the tradition of buying the best cables I could possibly afford(Leegeddy made me a pair in 2005 and recently IO had the greatgumbino make me a pair of SUPER HQ Actives and 20' XLR's so that I will NEVER have to worry about cables being the weak link in my chain
So my suggestion to you is either, 1. if you have the knowledge to replace or solder a pair of cables yourself w/ the best components possible(Neutrik Connectors/4% Silver-Based Solder/Belden 1804a or mil-spec silver-clad copper cabling/3:1 heatshrink and some techflex to make them even more durable OR 2. get someone to make you a pair of cables like that and you will never have that problem again(hopefully). Dont skimp on the cables and you'll be a happy tapir for a very long time! I can rest assured that I KNOW my cables are functioning properly ALL THE TIME and are also made w/ the best and most HQ components, and its one less thing to worry about in this fun, yet complex hobby of ours
Like I said, I just spent $170.00 on my 20' XLR's I bought around XMAS, but thats $170.00 I only have to spend ONCE, and I know that they are funbctioning properly for MANY YEARS to come
Good luck and I hope that your problem is ONLY a bad cable and that everything can be easily fixed/replaced
