While I agree that shorter speaker cables may not always sound better, certainly from the standpoint of subjective preference, I would add that nearly all speaker cable EFFECTS are proportional to length, and therefore DIFFERENCES between speaker cables will become smaller as length decreases.
Putting aside whatever effects connectors may have, the only speaker cable effect I can think of that would not be proportional to length (although it would still vary as a function of length) is the possibility that by acting as an antenna the cable could conceivably cause RFI (radio frequency interference) to be picked up and injected into the feedback loop of the amplifier, if it has a feedback loop. Which might under some circumstances, with some amplifiers and in some RFI environments, have audible consequences. Although I suspect that kind of effect is unlikely to be significant in most circumstances, and apart from shielding that may be provided in some speaker cables it would have little or no predictability with respect to cable type or price even if it did occur.
Good luck. Regards,
