Audiofail, you are right in a way.... Cheap interconnects (or generally cables) might be better and usually are better in certain systems,mediocre systems. Excellent cables (they usually cost more) are to transparent , to revealing , will show all imperfections of such systems and they would be "unforgiving" in inferior systems. Cheap cables will mask defects, they can be used as tone controllers in such systems.
Very good cables, neutral, transparent, detailed etc usually go with equipment of high calibre. In mediocre systems they will show how bad the system is.
Conclusion: cable application depends on the system.
And excellent cables will always be excellent but of course can't be used in any system.
Btw, you smell the same as Badwisdom, haha...
