That's a cool thought but moving the amps closer does not work in my living room.
I am not a EE so I don't know if the benefits of reducing resistance at some point become overshadowed but adding capacitance or inductance?

If the balanced signal cables are made longer then the added capacitance will form a low pass filter with the high input impedance. If the speaker cables are made longer the increase in inductance will form a low pass filter with the small impedance. In either case the similar effects are likely very small unless one is having the sort of week were one concentrates on minutia. Lockdowns can increase the frequency of such weeks.
Semi-related thoughts on speaker cables:
In the area of speaker cables there are potential issues with smaller gauge cables and longer lengths. If one were to build, for example, a switch box to switch between various amplifiers and a loudspeaker system to evaluate if a difference between the amplifiers could be heard, then it would be good minimize the resistance of the cabling. This can be done by maximizing the gauge of the cable, and minimizing the cable length. For example, using small gauge cables that were 40 feet long with say 16 gauge wires would be less than optimum.
At .004 ohms per foot, 80 feet of 16 gauge wire would have resistance of .32 ohms. The resistance would cause frequency response variations based on variations in the impedance of the loudspeaker. The inductance of the relatively long speaker cables would also form part of a filter that would somewhat reduce the high frequencies.
With any loudspeakers with passive crossovers, it is important to minimize the resistance of the speaker cable, but this is particular important for higher quality loudspeakers with higher order, precision crossovers and tight driver tolerances. If Salon2's were used for the amplifier test, then the maximum allowed length of 16 gauge speaker cable would be 9ft. With high quality speakers with passive crossovers saving a few dollars by using small gauge speaker cable can be a false economy.
