static electricity

I have found that when I walk across the room and touch my preamp, sometimes a tiny spark travels from my finger( static electricity) Nothing unusual in static electricty, but it produces a crackle sound in my speakers. The preamp is Audio Experience Mark II (all tube). IF I touch my amp ( Velleman 4040 tube) or CD player ( AMC CD6D TUbe) I never hear any crackle. Is this dangerous to the speakers, tubes or solid state circuits?? Should this happen? Hopefully one of you fellows with some engineering experience can help. All of the equipment has heavy duty, 3 prong, detachable power cords, and are plugged into a surge protector.

It shouldnt, i had a piece of gear i shocked about 5 billion times and it kept working.

if you just want to be careful run a slim strip of magnet wire up the side of your rack and make sure one end of it is connected to a ground source. anything metal should work.
Then just touch it at that should discharge the static build up so when you touch yer gear it wont get zapped
