heysplangyImagine thinking that shielded speaker cables actually do anything to begin with. This cable is obviously marked towards sheep who have no idea how electronics works. They also took down one of my previous comments debunking this cable.
Real hard fact: A coat hanger will have the EXACT SAME quality of sound as this cable. Ya sure brass has a little more resistance then copper, but it's negligible. The reality is that that a 20kHz signal isn't hard to transmit, the skin effect isn't going to be apparent at all. A properly gauged stranded copper cable will preform objectively the same as this cable, even better if you're using more amperage and a higher gauge.
A shield will do absolutely nothing because the signal in the cable carries power. When was the last time you heard noise come out of your speaker without your amp on? Noise has power in the nanowatts. Your signal going to your speakers from your amp is watts.
Save your money. Get a giant roll of generic copper cable of proper gauge. Don't believe the nitwits who think the sound has somehow "changed". Because there's nothing about a copper cable that will change the frequency responce. It's objectively a tiny series resistor in the 20kHz spectrum, your speaker's 2ohm DC resistance is probably 100-1000 times higher then the cable resistance.
