I started with bare wire with new cables.I always thought bare wire was best,made sense,when i used bananas it rolled highs,and took my system from front row,to third row.once the cables broke in,they sounded harsh and grainy.i sit close to speakers,about 9 feet,long story short i put bananas back and solved many colorations.my theory is in some cases,some wires are designed with termanation in mind.and no offense folks,but if you cant hear any changes,then what is all the fuss!.
