I’ve measured C in a 22 foot run of my AntiCables IC vs another 22-ft of IC with a conventional shield.
Wow, you must like soggy bass and rolled off high frequencies - usual single strand attributes - no damping factor. ( Yes I have heard the anti cables )
The above statement is only relevant to the particular shielded cable you tried.
Specifications for Anticables are 0.0095nanofarad/ft - 38 picofarad per meter.
I use a high gauge stranded silver phono cable - twisted pair with double shielding - only measures 48 picofarad in total including the connectors despite using much thicker conductors than the Anticables.
Generalisations can be dangerous - pays to check the specs.
