Does anyone know about these $20 component cables that are tested 40 MHz?

    Attractive looking cables that appear to be mass produced probably overseas. I'd imagine that for a short length of a meter or two, running from your DVD player they'd be quite serviceable. What would be impressive would be to have the cables serialized and a copy of the performance results enclosed. However, with all due respect, getting flat FR out to 40 mHz is not such a big thing.
    Of course if he keeps using the monster term in his advertising, it won't be long before big Monster sends a letter from it's attorneys!

    Those look like the GE cables that Target used to carry.

    There is something about the ad that makes me suspicious.

    I like that they try to give numbers, even mentioning the equipment they use to test (and that it's periodically calibrated) [​IMG]

    But some of the numbers they say dont match what I understand is needed. And they have a graph of db-loss vs frequency that goes well above what that scope could handle.

    I want to give them credit for trying to give good information. It's just ... something is a bit off (cant put my finger on it).

    You know Bob, I think you're right. I didn't read it very carefully and I've taken a closer look at their site. These are some of my observations.

    The dude at Blue Jeans says he tests every cable he ships, and I believe that. He even has switched his recommendation for analog audio cables in that the new one 1505F has better hum rejection than what he was using (he actually tested for that). At least there, he seems to know his stuff.

    I even asked asked Quad Shield RG-6, because most RG-6 cable has only one foil shield and one braid shield, and he went into detail about how you can have less *number* of shields, but yet still better shield *coverage*. And he knew about power cords too! [​IMG]

    Of course, learning from Chu [​IMG], I double checked myself, and the C is on the order of 17 pF/ft which is right in the ballpark for good cable.

    but probably not suitable for interconnects like for audio or dvd. i don't think that stops people from using them. i believe that's the conformable cable from Belden.
