Cable capacitance (plus load capacitance, which often dominates) forms a low pass filter with the output resistance of the source. Hence excessiviely high capacitance should be avoided. Once the cable capacitance is sufficiently low there is no advantage in making it any lower. So the rule is not 'low capacitance cables are better' but 'excessively high capacitance cables may be worse'.

So you agree high capacitative cables are worse. And about long or short?

Excessively long cables may be worse. Once sufficiently short, making them shorter brings little improvement. However, interference pickup (if a problem - often it is not) will usually be less on a shorter cable.

The thing to always keep in mind is that a well-engineered cable (i.e. almost any mid-priced cable from a reputable manufacturer, and similar DIY items) is by far the most perfect component in a domestic audio system. People only worry about cables when they don't know enough to worry about anything else.

All the sound goes through the air too - why don't people swap air? Surely the air in a good hall is better for sound than ordinary domestic air? Someone should bottle it and sell for a suitable price. Maybe someone already has captured it and is waiting for the right moment to bring out his Carnegie Hall 1958 or RFH 1976 vintage. The market is waiting!

the signal must pass around a circuit. That circuit can begin at the source Hot terminal and MUST return to that same starting point.
The cable that connects the source to the receiver must have two paths for current flow. The Hot sends the current Flow and the partner returns the signal.

A coax or a twisted pair or a star-quad can all do this Flow and Return thing.

The difference between all of these is what prevents interference from entering the Flow and Return circuit.

An unbalanced coax that uses the shield as both interference attenuator and as a return current route does not work as expected by the layman. Look at the different currents that can circulate through the shield to see what can happen.

An added shield that is connected ONLY at one end, cannot be part of a circuit. There is no route for the current to pass through. It acts solely as an interference attenuator.

Yes RFI is terminated by lifting ground. But EMI exists in the equipment and mains and its isolation is a little more difficult to deal with. Everything electrical generates EMI
The transformer in audio equipment working under this principle in the first place... Quieter power supply and noise floor rejection have been the aim of audio companies for years ' with ever more complex switch-mode devices. It's an ongoing evolution...
