99% of systems (including my own) have flaws or areas of improvement where spending the same money or time fixing those would yield benefits many times larger than messing around with cables. I do agree that using good conenctors makes a small difference. I use the neutrik earth breaking connectors for interconnects. For loudspeakers any decent quality gold plated plug will do. It seems fantastical almost that people spend so much time, money and effort on this issue when its really very straight forward. I guess its "easier" to think buying an expensive cable will improve your system dramatically when the alternatives are harder work and might actually involve having to chuck away a few items that the hifi mags recommend .
