Thread: Low capacitance cables

  1. #1

    Low capacitance cables

    My amp likes low capacitance cables. At present I have gone back to DNM after some Nordost.

    Do you have any suggestions for good low capacitance cables?

    thanks

    Speaker cables or interconnect cables?
    Low capacitance speaker cables means that the cable has high loop inductance. So high frequencies can be rolled of with some speakers.

    Look for designs with a fair amount of spacing between polarities and relatively small gauge. Not that they will sound better mind......

    But they very well might sound different with some speakers.
    (depending on the loudspeaker's impedance curve)

    But Kevin, all cables sound different ;-)

    The cables I used to manufacture (ICs), had capacitance of 3.8pF/foot, lowest in the industry. I am selling my cable business and I have a couple of interested buyers, so they may be available again soon. You could look for them used on Audiogon: called "holophonic-PC. They are very good unshielded silver cables.

    The thing to understand about capacitance, is that it is always important in interconnects, but particularly critical when driving from most DACs, because the output impedance of most DACs is much higher than the typical SS preamp. A quick back of the envelope calculation will show that even 10-15 pF/foot in a cable will result in roll-off at 20kHz with a DAC and the more typical 50pF/foot is really bad. I would beware the manufacturer that does not publish the capacitance per foot in their product specs.

    What values are you using for your calculation?
    DCS Vivaldi 2.0 stack, Metronome Kalista / Kondo KSL DAC, Soundlab A1 Px's , EMT927, SME3012R, ARC Phono 3, ARC REF40, VTL Siegfried II, TA Opus MM2 speaker and signal, TA XL digital, TA XL gen V power cables, CenterStage footers and Nordost Qkore8's!

    try 1K ohms output impedance for the DAC. 2 meters of cable. 100pF/foot for the cable. Destination is 50K input impedance. 10% loss at 20kHz

    100 ohm output impedance gives 1% loss at 20kHz
