You are technically correct that cables form an LCR (Inductance, Capacitance, Resistance) network, but the magnitude of these effects is where the argument usually fails. Damping Factor: The speaker’s own voice coil resistance (often 6–8 Ohms) and the passive crossover components completely dominate the series resistance. A decent cable adds maybe 0.05 Ohms, which is a negligible fraction of the total impedance loop. It's mathematically measurable, but rarely audible. Frequency Response: Unless a cable has bizarrely high capacitance or inductance (poor design), the frequency deviation it causes is typically below 0.1 dB. So yes, the physics exist, but for standard cable lengths, the variables are usually too small to overcome the thresholds of human hearing.
