    Default Do these Really work!!!

    While surfing I came across these snap on RF noise filters.

    Has anyone tried these out?? What are some of the possible applications??

    I've seen those, and alot of people swear on them. The majority of the time they're used on power cords, but have multiple applications as well. They're found everywhere, even on P.E./MP and at your local rat shack. When used on interconnect cables or power cords, it's usually near the component end where said-cable is near a bunch of other cables/etc.

    I use a similar product on all my power cords. Whether they work or not . . . who knows.

    It depends on the situation as to whether or not they make an audible difference. I use them and in some instances they are really effective. In other instances I notice nothing.

    When they are effective, you will notice a change by moving them up and down the cable. Sometimes just a 1/4 inch will make an audible difference. Place them at the input side of the cables. The best distances I have found are anywhere from 2-4 inches away from the end of the cable, YMMV.

    Oh, and $14.50 is a ridiculous price for those.

    They can make the biggest difference when shielding your cables from HF stuff like HAM radios, etc. But they can also make a difference if your place has some bleedover radiation or a strong signal from something near by.

    I didn't think they were very expensive, especially if they improve the sound quality.

    So if I put them on my interconnects I should expect to see a Difference?
    Has anyone tried them on speaker cables?

    Speaker cables are not nearly as subject to RFI/EMI as IC's. Also they would go near the amp end, and not the source. I would presume that you would want to protect the most cable you could. Also I have no idea if they would degrade the audio signal. I have only seen them on power cords. They cost much less than a $1 for companies who buy in bulk, and If they worked you would most likely have seen them by now, but who knows they may not be detrimental to the signal. For a couple dollars it may be worth trying if you are having noise problems.

    EDIT: A little side note. I don't see them on any of the cables he is selling;)

    They don't improve the sound quality at all. They remove unwanted noise in applicable situations.

    If they remove unwanted noise in applicable situations wouldn't it make sense that they improve the sound quality?

    If they remove noise from AC then it makes me wonder if they remove any musical material too. Sounds like a candyliquor upgrade. He now has red letters.

    I was thinking the same thing. I usually see these things on DC power cords (ie. laptop computers).

    SAL they work on power cords, but do you want something that filters unwanted frequencies from power on a low voltage wide bandwidth analog signal? I wish I had a silly scope. I would like to check the numbers and put my ears on it, but it really doesn't sound like a good idea. Again all the cable companies out there, and none use metal ferrite chocks. An air filter filters air, but I am not going to filter pond water with one and drink it even though it is a filter.

    To the average consumer, this would be the case. That said, they still do not improve the sound.

    It seems like no one is really sure if these will improve, degrade, or have no effect on the sound....I smell a DK review coming.
