It never ceases to amaze me what people will pay for digital signal cables. Just 1s and 0s as long as they arrive at the load in the same order they left the supply we get reliable data cable.
I have a local electronics wholesale that sells HDMI cable for $10 and $80. One has a big Audio brand name. Dispite his recomendations to customers he still sells a lot of the $80 ones.
Take a European house panel and gold plate the neutral and bonding terminals and you can sell them to Audiophiles for $3000. A 10 fold markup for absolutely no benifit and no recognized electrical approval or listing for use in any North American market.
