Regarding the possibility that audio components can be designed to be insensitive to cable differences, in the case of line-level analog interconnects Atmasphere has described the design criteria which would accomplish that. And he has offered what I consider to be compelling proof of his contention. See the first of his posts dated 3-22-2013 in this thread. Also see my follow-up question dated 3-27-2013, and his response thereto.
Unfortunately, though, it seems that for whatever reasons the designs of the majority of high end audio components do not meet one or more of those criteria. And my impression is that it is more common for pro audio equipment to do so, presumably in many cases as a consequence of the need for that equipment to be able to drive long cables.
And regarding sensitivity to speaker cable differences, as Ralph (Atmasphere) has said in a number of past threads that will be minimized, at least, if the speakers have high impedance and if the cable length is kept short (as would be facilitated by the use of monoblock amplifiers).
