Surge protection, no filtering, no regen please...

http://www.solahd.com/products/Index.htm

Since I also like to plug my amps directly into the wall socket I installed a pair of Sycom surge protectors in my main fuse box, here in Wisconsin there are plenty of thunder storms.While one would do the job I installed one at the top of the panel and one at the bottom.They are about $120 a throw so not a large investment by any means and also may protect your appliances,stove,fridge ect.I'm no electrician but the install was a piece of cake,but always use caution...of course.
Just a thought

Install a whole-house surge arrester at the main panel. This will protect your equipment from lighting as well as transients from arcing light switches and refrigerator motors. Consult an electrician for what's on the market - there are some inexpensive ones that do a good job. Look for something that handles at least 50,000 short-circuit amps and over 500 joules. But keep in mind that lightning strikes are never fully protected against unless you have an engineered system like the ones on airplanes and radio towers, for example.

Again, consult an electrician - surge arresters are useless if your grounding system is inadequate.

Ditto Gs5556. Whole house surge protector lets you sleep easy. Also like the Brick Wall devices.
