Seems to me there is still a MILLION dollar challange for anyone that can prove the difference between speaker wire costing thousands and the cheapest monster cable. Noone has taken the offer in what now, over a year. Hmmmm
As someone once told me,
copper is copper, God only made one kind. The electrons can't tell the difference. As long as your using the proper AWG for the distance and speaker rating you will not be able to tell a difference in true blind A/B tests. If your aware of what is hooked up, your brain will tell you your listening to $1,000 copper wire.
