Ferrite cores on DC cables?

I was just looking at some of my various DC power cables and noticed some of them have ferrite cores. This of course got me thinking if ferrite cores have any positive effect on the sound when used on DC power cables?

I just spent the last week with ferries on all my DC cables ... Removed them tonight and the music sounded better (dynamics,tone,timing).

 

HDMI cables are the only cable I have found that benefits from ferrite, don't know why.

 

Moved my psu's (Aries and hdplex ) further away from gear and carefully routed the dc cables away from ac and other types of cables has provided a very subtle benefit, while my dc/ferrite cable test was not a win for me in my system.

If noise & interference are using a cable as a sneak path to get into a component, then yes ferrite chokes can help. There is more to using ferrite chokes than just placing a random choke on a random place in a cable.

Can you please elaborate? This is very interesting.

I use the clamp on cores on the ATX molex cables in the PC that connect the sound card & usb card (as well as rfi shielding around these). It has made a notable difference with the sound card audio performance, which is used for muti-channel duties. I also bought a few extras and clamped them on all the mains cables nearest the IEC socket for the PC & DAC.

Can you point me to whatever brand of ferrite clamp on cores you bought? As these look to be pretty cheap I am interested in trying this out for myself.

Go to Ebay and type in Ferrite cores. Plenty to choose from.

 

Right, but I was not sure if there is a difference in quality between brands that could impact the sound.

Ferrite chokes/clamps are RF noise filters put there on purpose. They reduce amount of radio frequency noise that can be picked up from air on the cable and travel through it messing with things like increasing jitter. (open cable outside a shielded box is like an antenna)

 

For example on HDMI and DVI display cables they reduce / remove data transfer errors, otherwise you may see occasional wrong pixel colors flashing shortly on the screen.
