It's highly unlikely that any cable would have an impedance of 50 ohms. They are surely talking about Characteristic Impedance which is totally different. Capacitance is more critical in an audio cable. Capacitance has to do with the effectiveness of the dielectric between the legs of the cable as well as the proximity of one leg to the other. High capacitance may cause smearing of the signal hence a loss of detail and definition of the leading edges of notes.
Explain speaker cable resistance, capacitacance?
Can anyone please easily explain, without going too technical, the effects on sound of resistance, capacitance, inductance in speaker cable?
For example, these are the specs of two cables made by the same manufacturer:
CABLE 1
Resistance: 0.9 Ohm/100 m.
Capacitance: 17.5 pF/m.
CABLE 2
Resistance: 0.34 Ohm/100 m.
Capacitance: 32.5 pF/m.
What differences should be expected between these all other things (lenght, system) being equal?
Does the same apply to interconnects?
Thank you for your support :)
