The characteristic impedance of a cable has very little direct relationship with it's use as an analog interconnect.
However, capacitance, resistance, aand the inductance can all combine to affect the measured frequency response IF the values of these become high enough to actually affect the audio band FR.
Typical cables do not have enough inherent capacitance to attenuate the HF's in the audio band, the one exception is when a cable is paired with a passive "volume contriol", and the very high effective source resistance of the control can work in conjunction with the cable capacitance to roll-off the HF's within the audio band.
This kind of roll-off is usually not a good idea, as it will not really tame room acoustics, but it will blunt transient response and cause a loss of "air".
Create some inexpensive DIY room treatments to get your sound back, see:
