| Originally posted by Demolition I recall reading a well-written post describing this effect at Audio Asylum. Can't find it now but, as I remember it, the theory goes that power cords with ferrites constrict the current bandwidth leading to your system. This is most noticeable with amps as their capacitors go through their drain/recharge cycles. If you get a particularly powerful transient (loud musical passage perhaps?) during one of these cycles, the amp will try to draw extra power. However, because a ferrite increases the inductance of any cable that it's looped around, it could cause a delay in the capacitors recharging. The resulting voltage sag causes the sound to either distort or sound dull or lifeless down the line (i.e. in your headphones or speakers). That dullness is what people mean when they say "constricted dynamics". Of course, I've never noticed this because I don't have the so-called "golden ears" that some people do. My ears aren't sensitive enough to detect a momentary dynamic drop such as that. As for ferrite use on computer power cords... the added EMI/RFI rejection will be a benefit. -- I've found the Audio Asylum thread that I mentioned earlier. It will explain better what I was trying to get at. Thanks, tortie. I'm in for three (3). I have some non-audio equipment that would benefit from the extra EMI/RFI protection. D. Edit: added the Audio Asylum link. |

| Originally posted by Sovkiller I think that if you power supply is properly designed, you will have the power you may need for any transient in the music spectrum, and if the caps are big enough will supply that power in the right moment, I had used ferrite all my life and with or without, I hear no difference, remember also that a good power cord is that last tweak to make on a system, most of the times if the system is not extremely efficient you will not notice anything even from an ultramegabuck cable.... |
