Over the years I have has various cables in my system ranging from entry level Acoustic Research to high end brands like Straight Wire, Wireworld etc.
Recently I have tried Belkin Silver Series and they seem to give 90% of the performance at a fraction of the cost. In Canada a 4' interconnect pair sells for $40. Unbelievably inexpensive for the performance they provide.
Their stated goal when they introduced AV cables was to knock Monster off of their pedestal.
