tboooe Posted February 9, 2016 Share Posted February 9, 2016 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? 12TB NAS >> i7-6700 Server/Control PC >> i3-5015u NAA >> Singxer SU-1 DDC (modded) >> Holo Spring L3 DAC >> Accustic Arts Power 1 int amp >> Sonus Faber Guaneri Evolution speakers + REL T/5i sub (x2) Other components: UpTone Audio LPS1.2/IsoRegen, Fiber Switch and FMC, Windows Server 2016 OS, Audiophile Optimizer 3.0, Fidelizer Pro 6, HQ Player, Roonserver, PS Audio P3 AC regenerator, HDPlex 400W ATX & 200W Linear PSU, Light Harmonic Lightspeed Split USB cable, Synergistic Research Tungsten AC power cords, Tara Labs The One speaker cables, Tara Labs The Two Extended with HFX Station IC, Oyaide R1 outlets, Stillpoints Ultra Mini footers, Hi-Fi Tuning fuses, Vicoustic/RealTraps/GIK room treatments Link to comment
tranz Posted February 9, 2016 Share Posted February 9, 2016 I have bought a few clamp on ones from an electrician store. They are super cheap to try, but cannot say I heard a difference. Link to comment
Duke40 Posted February 9, 2016 Share Posted February 9, 2016 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.

Speedskater Posted February 9, 2016 Share Posted February 9, 2016 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. Link to comment

dean70 Posted February 9, 2016 Share Posted February 9, 2016 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. Alchemy Desktop http://www.origen.net.au/Alchemy/ Link to comment

Miska Posted February 9, 2016 Share Posted February 9, 2016 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. https://en.wikipedia.org/wiki/Ferrite_bead Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
