Good idea Bob. I have a few of them in my stereo junk draw that have been supplanted by other stuff in my system. I never really thought about using them in other parts of the house.

I will have to give that a try.

Don't forget to use them on the phase opposite the one your system is on.  Remember:  the Neutral is common to both phases. Load to Neutral noise contamination is common to both.  Applying a QuietLine or other Load to Neutral device is always best placed at the same point as the offender.


Wall warts
Cable or satellite receiver
Digital clocks
Tool chargers - they are some of the worst
Surveillance cameras
Any lamp with an LED or fluorescent bulb.  Better yet, throw those MFers away! A couple of bucks a month is a small price to pay!

Again, if you are capable and confident to do do, go around the house once a year and tighten the screws on every receptacle and switch.  Oxidation = RFI due to micro-arcing.

Clean every plug in the house and treat with a good contact enhancer.

[sidebar: clean all of your interconnects and speaker connections regularly.  This is particularly important if you are a smoker.  Electrical connections have an affinity for smokey ions]

Do those last three things one room at a time, say every week or month to make it not a drudgery...

You will be amazed at the improvement in SQ due to noise reduction, especially in the in the context of space, depth and width of soundstage.

Again: everything effects (and affects) everything.

If you get a few .1uF X or Y rated caps and plug them into your outlet using one of those plastic electrical outlet safety caps to hold them in you will have essentially duplicated what a quiet line filter is for a fraction of the cost. You can even add a varistor to it for a little surge suppression assistance.


Ive got noise coming from my speakers Ive had a couple of people over to help trouble shoot it could never find the cause. Very frustrated.

Do tell.  Explain what you are hearing and its' level relative to a good listening SPL.

A short list of things you have tried will help, too.

Maybe between we can do the telefix thing between all of us.

However, I had a Quietline filter plugged into the same circuit as the TP Link and it "filtered" the digital signal... Removed it & all worked! LOL!

Hi Pete,

Were you joking when you commented about the TPLink?  I ask because I added one to my wireless extender (a Netgear) and suddenly I am getting dropouts in signal.  :?: :!:

I removed it, and the Internet works again! Can these things interfere with wi-fi and wired signals?

Anyway, I used one on the wireless extender, two more on an extension cord where all my LED lights are plugged into. I think it removed some vocal harshness  :-k
