Calvinj,
you don't always have to hear the cables to know if they're going to be better or worse than something, for example your cables use inferior OFC wire which is 70-year-old technology OCC single crystal is far superior and rectangular OCC single crystal is even better than the round, single crystal wire was proven over 50 years ago to be far superior to anything OFC at any price, you can't change the law of physics, OFC wire has 1500 crystal barriers per foot which are little fractures in the wire OCC single crystal has none in 125 m so the signal doesn't have to jump through little fractures in the wire that act like diodes and sheer off harmonics, maybe you should get some and put it up against your overpriced wire but get the wire that's similarly priced to yours and you'll see that it'll absolutely blow yours away, The neotech Sahara and Amazon which is the silver and copper rectangular OCC will leave your cables in the dust.
