Static remover.

Thanks for all the good information.

Its nice that you are using a humidifier but is it large enough or are you throwing your money away. Humidity is calculated by Cubic Feet not square feet because the moisture will move to the dry area. Check with a humidistat and the spot to hit is 40% and up in entire house. let it sit for about an hour. I'm an HVAC tech. There are Grounding straps you can get easily in an electrics store or Web they use them all the time to work on computers. Run a wire from screw on any electrical outlet and touch it before you touch system will work also.

@robert53,

I believe the device you're referring was from Audioprism. It would seem to be an easy DIY project.

Go online and Google small anti static mats.  I bought one for 20 bucks and cut it to size.  It comes with a ground wire you attach to the screw that holds the wall receptacle cover to the receptacle.  You shuffle over to the system and touch the mat which I have on the top of my rack under the TT.  No static or harm to system.  Works better than any spray and is inexpensive.

Static Guard is real effective https://www.amazon.com/Static-Guard-Fabric-Spray-Ounce/dp/B0013IRBG4 Use it all the time. Spray this over your cables, experience cleaner, clearer highs. Even when you don't think static is a problem, it is. Cable Elevators make an even bigger improvement.
