Static Shock?

I have been experiencing the same thing. When I wear my house slippers I always get a nice jolt. My Hi-Tech "hiking boots do the same thing. My tennis shoes do not produce the static. Neither do my bare feet.
I have isolated the source of the static and it has to be the material from my listening chair.
It doesn't matter if everything is powered down or not I still get the same jolt when I touch any of the knobs.

I'm not sure keeping the window open is such a good idea, as you're just letting cold dry air in, and letting warm moist air out. The furnace doesn't take any moisture out of the air. What happens is the relative humidity drops when you heat air up. This means the air feels drier because it can absorb more moisture when it is warm. With the window shut, the humidifier and your breathing will fill up the air's excess absorbtion capacity, and increase the absolute and relative humidity. By opening the window, the moisture from the humidifier and your lungs will leave the room. The cold air outside may have a high relative humidity, but it has a lower absolute humidity on a per volume basis than the air you are letting out of your room.

Static electricity in a fireworks factory - now THAT'S a serious problem!!!!

I live in So. Cal. & in the fall when the Santa Ana winds kick up the humidity drops down to single digits. This can create some serious finger arcing. For some reason during this condition when I touch my Krell KRC2 pre it will send it in to "mute/standby" mode. I will have to reselect an input, then take it off of mute. I have gotten into the habit of touching the rack first almost every time. The humidifier sounds good, but I wouldn't want to introduce any type of corrosion enhancer to the equipment. I just need to ground myself out. Wood doesn't conduct electricity so it must always be metal in my house.
Fireworks factory, where is the smoking section..?

Simply touching the rack first works in my system. I also remember reading somewhere that someone had a bare copper wire hooked to their rack and they slid the wire through their hand before touching the system.

As suggested earlier, a humidifier will provide significant improvement. A whole house humidifier connected into your HVAC system will help the humidity and make your home feel more comfortable.

Enjoy,

Ground the rack and be sure to make contact with the pillars/ground,before contacting components.
