Therefore the claim that "That usb cable added so much noise and treble clammer that it infected my soundstage with a high pitch wale that reminded me of an old dot matrix printer pounding out copies." is either completely false, which I doubt, or just proof that the original usb cable was somehow faulty and not functioning properly.
Please understand that I am not looking to pick a fight but rather just looking for a little clarification. Anyway thanks in advance for helping to clear things up!
USB cables carry data AND power. That is why Hard drives can be self powered by leveraging the power available on the USB port
Werd stated that he used a generic cable that came with his printer.
Printers are not self powered...so the noise he got could have been due to the generic printer cable not being designed to support self powered drives OR not wired/sheilded/terminated correctly for any other application aside from the printer in question
Rememeber manufacturers will cut as many corners as possible so if they can save 2cents per cable by making it support just their specific application, they will.
Hence my comment that before leaping onto a high priced "hi end" USB cable, check out a well made Belkin cable specifically designed for hard drives.
Its the same idea that you dont use a 10amp power cable on a 30amp curcuit. Sure the 10amp cable might work some of the time but it wont support the required peaks when they hit.
