Audioquest has been a manufacturer of audio cables for many years and my understanding is that they have good products.
However cables are very system dependent so even with the 70% discount, if the cables does not sound good (or make a difference) in your system, not worth it to purchase.
Do expensive cables make a difference?
Short answer, no. Even expensive cables/interconnects can make no difference. It’s good to read stuff, but with cables, etc. it’s best to identify what aspects of sound are important to you and what you’d like to improve in your system and use that to choose some cables to try and see nothing happen.
Do more expensive HDMI cables really make a difference?
Expensive HDMI cables are a rip-off and offer no difference in picture quality over cheap ones. Salespeople, retailers, and especially cable manufacturers want you to believe that you’ll get better picture and sound quality with a more expensive HDMI cable. They’re lying. You see, there’s lots of money in cables.
