Cable capacitance
Posted: Tue Nov 12, 2019 9:43 am
Before I ask my question, here's my disclaimer, I know very little about electronics or DIY audio so please forgive any daft questions. My aim is to make my own interconnects, I am comfortable using a soldering iron etc however I am too some degree confused by all the different claims and counter claims made by the manufacturer's of speaker and interconnect cables. Prices vary widely from budget through to cables that must be made by Fabergé out of unicorn hair mixed with unobtainium.
I know Richard was totally against any Litz cables and always stressed the importance of low capacitance. I also know winding wiring increases its capacitance but that's where my knowledge stops. If for example a cable was made up of say 4 cores, each core consisting of 10 twisted fine strands, covered by a good quality PTFE insulating cover and then the 4 insulated cores were wound around each other would the capacitance be greater or the same as if the 4 cores were joined in a parallel fashion. So in a nutshell does the insulation prevent an increase in capacitance ? Thanks Paul
