69.137.5.160
Moved to Naples, Fl., remodeled a house and installed an Environmental Potential 2050 whole house surge protector. It has a built-in filter for high frequency noise (rfi, I guess). My system sounds better than it ever has. All other variables I can think of have been accounted for including cleaning and doctoring power cables and interconnects. There is more of the lowest level sounds, details and ambiance than I've heard before. As old as I am with tinnitus and poor hearing, the change/improvement was and is noticeable. I got the idea from this ward so "Thanks, Guys".

The EP 2050 has two lights, one for each 120V leg. If the unit does it's sacrificial thing, one or both of the lights will go out.
I've had my 2050 for over ten years, five of which in Costa Rica where the power really sucks; outages every week, usually banging on and off several times before it finally goes. Nasty lightning storms during the rainy season. I've measured the AC as low as 98 and as high as 134. Never lost a piece of gear there or in the US. My 2050 lights are still on so I know it's doing it's job.
I don't know if there is a correlation here but in Costa Rica I installed the standard Eton whole house solutions for several friends (the only thing readily available in this remote part of CR). In both cases they lost plasma TVs, even with the Eton.
I also agree with the other posters. The audible improvements are fairly obvious. It does more than just filter RFI. As far as I know, this is THE whole house solution. Anyone find anything better?
i use a 2050, but also got incremental improvements (of greater amount) by adding a 2nd dedicated ground rod for my dedicated room, along w/ dedicated lines / AC outlets (ATLs) and wall plates. the 2050 is great, but more can / should be done.

Yes, I did pretty much the same; three ground rods in an array (looking into the stuff that replaces the soil around the rods for a better ground) and 10 gauge runs from a dedicated, 60A sub-panel. In addition, I have individual custom power conditioners with DC blockers, ground filtration and AC filtering on each component (got many good ideas from the Felix Project thread over on Audiocircle). Still, at certain times of the day, the line harmonic distortion rises to over 6% which causes problems. I tried working with our utility to no avail. Now working though the state corporation commission to get this issue resolved.
If I had the money, I would replace the sub-panel with a giant balanced power solution like you find in the best recording studios.
Unless you are generating your own power, there are multiple solutions that will give you incremental improvements. For those doing nothing, the EP 2050 would be a great way to start. This whole house solution will protect all your appliances as well as improving the performance of all your home entertainment systems.
I had one installed after a surge blew out one of the amps in my Vandersteen speakers. It protects and improves the performance of my stereo. No down side at all.
I was prepared to struggle to hear the difference it made, but the change was quite obvious. Other tweaks that have caused similar improvements have been crystals--cheap and quite effective when you use the right ones--and just recently the Black Discus from Mad Scientist Audio.
