While I haven't taken the time to study the specifics of Doug's system, speaking generally Bombaywalla makes some very valid points IMO.
In a post here from a few years ago I summarized many of the ways in which cable behavior can be expected to vary widely depending on the characteristics of what the particular cable is connecting.
For the most part, these dependencies have no relation to the musical resolution and sonic quality of the system. Assuming that musical resolution is not grossly deficient, systems at any price point can be expected to vary widely in their sensitivity to cable effects. A very expensive very high quality system can certainly be designed such that it will be less sensitive to cable differences than many lower priced systems. For example, consider the post by Atmasphere here, regarding interconnects. Note especially the proof he provides of his contentions, which IMO is highly persuasive.
