Average Joe need line conditioner?

    As many of us know in the electrical/electronics world, all home
    electronics equipment has a form of filtering associated with the a.c.
    line and/or the filtered d.c. down the path. Series noise filtering can
    be a line transformer as you would find on better equipment or an rc
    network as found on direct line connected equipment.

    I see these "line conditioners" in the stereo/tv stores selling for as
    much as $500.00 to $1500.00. These units clean-up noise as well as
    stabilize the 120 volt line voltage.

    As I have come to understand, the need for these units is grossly
    exaggerated by salesmen to unsuspecting customers, as the line noise
    levels are already reduced to acceptable levels in the tvs/stereos in
    general.

    I am inclined to agree, unless you're doing hi-fi recording, in which
    case you might spend 200 bucks on a furman power conditioner if there's
    something especially noisy in your neighborhood. But usually if
    something is making noise on the power line, something isn't working
    right, and the power company can be talked into at least looking at
    it.I can't imagine what might be in the $1500 one that would make it
    that much better.

    I once saw triple shielded optical digital audio cable made by monster
    in a fancy stereo shop.

    Yes they're mostly snake oil, since just about any equipment steps down the
    line voltage with a transformer, rectifies it and filters it interally you'd
    have to have a LOT of noise on the line to cause any problems, especially
    for better equipment with well regulated supplies.

    Unless you are into the very high end stuff it is a waste of money.

    Speaking of the monster stuff, it gets me that they (or someone like them)
    sell a special replacement 120 v cord that replaces the one that comes on
    equipment for about $ 100. What good would that do when you have about 50
    feet or more going to the breaker box and alot of aluminum cable going to
    the power pole ?

    PCB-free snake oil, I hope.

    I would add that *if* you're into the very high end stuff it's all a waste
    of money IMO. There's good equipment, there's very good professional grade
    equipment, then there's audiophool grade equipment which differs from the
    former two mostly in price and marketing.

  11. I can't even miagine a million dollar recording studio plugging their
    equipment into a $100+ outlet.
    It's true that the cheapest $0.79 outlets are not reliable and after
    several cycles of inserting and removing plugs, they loosen or break.
    So when I change an outlet in my house or for someone else I reccomend a
    more expensive outlet - about $3.00 - $4.00 each.

    I'm surprised it's not touted as an alternative to wiring your amp
    directly into the breaker.

    Does anyone sell oxygen-free THHN wire?

    I get Leviton for around a buck and have never worn one out or broken one.
