Whew! A few paragraphs might have helped. Yes, cables matter, but in a low end system there isn't a great discernible difference in equivalent cables, so why spent a lot? What is not very well explained is the equivalence matching of cable to system.
My humble view, to go along with my shallow pockets, is that few general users use their systems to discern the difference between a Bösendorfer, a Steinway or a Yamaha, and although I have listened and loved to classical music for decades, I would be hard pressed to hear the difference between one brand instrument and another, regardless of the HiFi system or cable I had.
Their are audiophiles and Audiophiles. Just how far do you want to take it?
