You need to put some reasonable parameters on this. If you *remove* any part of the system it will not work. If you get the worst possible option for any part of the system it will be bad. Speaker wires don’t matter unless they are 200ohm ultra-high inductance wires running next to your mains cables - then they are the worst part of the system.
However if you take some kind of typical Hi-Fi system then it is extremely likely that the speakers are the worst component in terms of linear and non-linear distortion. It is pretty easy to make very good amplifiers, sources etc
