Static

Get a humifier for the room your having issues...Just turn it off when listening to music..Winter dryness makes things worse..Once the weather warms up and you can open a window the problem will stop..Also don't drag your feet on the way to the Volume control........

You couch is made of a very static-y fabric. Cover the place you sit with a cotton fabric, or leather. It will not generate static.
In the meantime, touch something ELSE FIRST after you get up and discharge the shock through a lamp or whatever...

The simplest solution...don't wear rubber soled footwear when listening. I only have socks on my feet when in the listening room! Never a shock.

I agree with all three replies so far. Run a humidifier, do NOT listen while wearing rubber soles, and I usually touch my metal rack before touching the tonearm or CDP.

One more thing I do is hit the mute button as I get up to change a recording.

Cheers,
