Power cords - snake oil?


Excuse me for being skeptical but how in the world can a different power cord improve the quality of sound? I've been willing to upgrade my interconnects and speaker cables to a point and use a line conditioner / surge protector but why spend hundreds on a funky power cord ?

Ken: The Cable Company offers this service on the cables/cords that they carry. I would ask Brian at BMI directly about his products as I am pretty sure that they are still sold direct. Other than a local shop or the Cable Company you will just have to check out each manufacturer. Many have a 30 day return policy. It's a lot of work, but better than buying and reselling, I agree.
Ditto, D-K above. Also, if you get 1 pc on trial, try first on pre or cdp; when connected, let the pre/cdp play a bit before you embark on serious listening.
I have been reading these posts on power cords for a while. As Snooker says, everyone has an opinion. I will make an analogy to an expensive bicycle; manufacturers will cut on the less noticed components (ie. seat post, bars, etc.) to maintain price points. In stereo equipment, one of these areas may be the power cord.

Although I am no expert, it seems the power cord has 2 primary functions, to transmit current and to keep out noise. Larger gauge wires carry more current. Better terminations on your cord (and a better wall outlet) should reduce losses and noise. Shielding and ferrite suppressors help keep out noise. I have one (somewhat) expensive power cord and it runs to my main 2-channel power amp, since the amp draws the most current. My other cords have been upgraded to Volex or Hubbel 14awg shielded cords with ferrite suppressors added. By going through an electronic supply outlet for both the cords and suppressors, the cost was relatively low (about $20 per cord). My next upgrade in this area will be having the electrical in my house upgraded with dedicated power lines for my stereo equipment. These upgrades have worked for my associated equipment. If you have an expensive system, you may notice a difference with better cords on all components (and don't forget the power conditioner - another thread!).
Hey Leafs, did you actually try the boiling water experiment yourself? If so, that is a great way of explaining why aftermarket pc's make a difference. After many tests, and after reading many of the power cord debates, I almost automatically upgrade the pc on any new component. Even pc's in the $150 price range make a noticeable improvement.
Ken1, I'd recommend searching for members who own the same equipment you do. There is a thread on systems people own or try the virtual systems. There advice is the best you'll get in that cords are so system dependant. My Sony SCD-1 is far and away best with the NBS Statement. I've tried A LOT of cords and if I was asked by a Sony SACD owner I'd advise to start there.

Leaf, I want to here more about your water boiling. Please start a new thread on it, sounds like you could raise some good discussion.
