brass outlet covers...anyone try them? Sound good

just of our curiosity, are you referring to the outlet recepticle (i.e what you plug your power cables into?) if so then i agree with you that outlets do make a difference. I cant understand your findings about the center mounting screw though. any ideas why different levels of tightness makes a difference?

>>I also then messed with the position of the center screw. Having it really tight was like taking the air out of the music. Having it really loose (sticking out slightly) seem to have a bit loss in the focus. Having it tighted just by hand so it is just snug proved to be the winner.<<

This is all a joke right?

To quote John McEnroe, "You can't be serious".

I hope this is a joke but if it's not please list your other system components in order to determine what quality level one needs to attain so that duplex covers enter the tweak realm.

So, depending on how close your speakers are, room construction, type of AC outlet and overall system performance it could make a nice improvement in sound when you swap out the cover.

A 2 3/4" by 4 1/2" electrical cover of surface area 12 square inches in an average 16 by 12 by 8 ft room with total surface area of roughly 120,000 square inches.

This makes less than 1 hundredth of 1 percent of the surface area???

Surely, in order to make a "nice improvement in sound" then

1) the cover would need to be totally loose and rattling terribly - unusual but possible.
2) An extremely stiff power lead connected to a humming device (transformer or shaver or something like that) - again unusual
3) next to one's ears (listening position on the floor near a wall) - again unusual

I can't see that being simply close to a speaker would be enough. I also can't see how changing the cover material could be possibly be enough to be audible under ordinary circumstances.

Have I experimented like Freemand? No....but come on guys! It ain't April the 1st is it?

Audiofell, you're not forced to spend the .69 cents, I would not worry about it if it offends you. I still think it's possible to hear the drum effect of an outlet cover and in any case, it's a harmless experiment that forces the user to pay attention to their AC connection.

I think there should also be discussions about cleaning RCA connectors, AC blade connectors and speaker spades (or banana) too. Cleaning all of these are audible and always an improvement.

Many times I've gone through my system, doing nothing more than "housekeeping" cleaning of connectors and gotten significant improvement.

In fact, I think sometimes audiophiles doing equipment testing, plugging and unplugging tubes, cables or AC connections the new piece of equipment gets a slight advantage because that connection is improved in the process.

As Neil Young says "Rust Never Sleeps," (neither does oxidation :^).
