Vandersteen x-over and IC?

Since much of the sound of an interconnect is determined by the RLC electrical parameters of the IC and the output and input impedance between the components, does the use of the 2Wq x-over box that connects between preamp and amp alter the or change the perfomance of the main interconnect attached to the x-over? I would imagine the x-over and its capacitors alters the electrical relationship between the pre and amp - but I don't know.
