Noise filter for receiver?

On another forum (yes, there are others!) I've been discussing the use of line filters - noise filters - between the wall outlet and the receiver power cord.
I was a skeptic - but after trying everything else to get better sound, a British chap convinced me to at least try such a filter.
To my amazement - it worked! Well, at least the amplifier sound was better, by which I mean fuller, with better bass.
I've been taking the filter off and on - and hear the difference every time. My wife says the sound is clearer. I say "fuller."
OK - how about some input for the ole scribe? Are my wife and I "hearing things" or is there some rationale for using these noise filters.
I've got refrigerators, fluorescent lights, dimmers, and a large electrical transformer across the street. Pretty "dirty" electricity, if you ask me!
Got my filter at Radio Shack - about $35 - has RFI filter, et al. Would like some feedback on either my idiocy or brilliance!

Its idiocally brilliant ...
How could it be bad if it has a positive effect on what you're hearing ? ... -
OW
which one did you get is it a powerbar/surge/filter ?? -
Yep, Rick - idiotically brilliant. Call it dumb luck, also?
Willow - nope, not a power bar - this is a liddle black box that you plug into the wall outlet. Has a green light (whoopee?) and you plug your power bar, or amplifier, or whatever, into it.
It's about 4 inches by 3 inches in size - maybe slightly larger.
But - just because I noticed a difference - well, you know!!!
G R I N Larry R. -
EMI/RMI is it the higher the noise filter the better say 58dbs vs 35dbs ??

Yep, Willow - go for a filter that has at least 40 db reduction, and has reduction that starts at 100Hz - not 150 Hz, as many have. Leviton has some good filters - about 22 bucks a pop for 5 amp ones. Try Google and plug-in noise filters, and see what comes up. I think maybe Home Depot or Lowe's might have some of these. The Radio Shack ones are surge protectors plus noise filters, and thus perhaps not as good as the Levitons, etc.
The more I read, the more I realize how "dirty" the electrical supplies can be. In my case, I guess I've got lots of stuff putting out all sorts of "dirt." Sigh.
OK - hope that helps a bit. Never thought anything about it, until I did the "filter" thing - and now I'm going to put little plug-ins on refrig, computer, etc. just to isolate any possible source of, well, "pollution." (also getting pointed aluminum hat to ward off the alien invaders! GRIN)
Have a good night - and two martinis! Larry R.
