I had the same problem, living here in colorado with thew draught and all, its been very dry.
There were times where i would touch my volume knob and get hit by a vicious arc.
To get by this. well, to prevent my stereo from being hit i ran a thin line of copper up the side of my audio rack, and grounded it out. I made it a habit to discharge myself before touching the gear by touching the copper wire.
It still sucks because i still have to shock myself, but at least it doesent damage my gear.
You could also get a humidifier, but you gotta be kinda careful with those. You dont want them too close to anything
