Or their hdmi cables.
I have had at least 2-3 monoprice hdmi cables that just fail on me all of a sudden, while the supra hdmi cables are rock solid for 7+ years
The Supra HDMI cables are indeed very good and I love the detachable connector housing to allow them thru pipes.
But it's hard to justify the 79€ price tag for 2mt, it's definitely a bit too on the high side.
Most HDMI cables in the market are terrible but HDMI has a certification; regarding signal quality and integrity you just need to buy one with the certification.
Durability is always a bet but I have to say that all my good HDMI cables are still rock solid after 10+ years, regardless of price, so...
The best HDMI cable I have (judging the eye-diagram on the protocol analyzer) is from one of our STB supplier and it costs less than 5€!
All other fancy & pricey cables that I've tested are worse, often much worse.
Especially the most expensive ones!
The Supra speaker cables are fine as well as I can see but honestly I'm not sure if they are worth 5,5€/mt.
There are cables with bigger diameter and more copper strands for €4/mt on Audiophonics.
But they are not made in Europe for sure.
I'd be more inclined to spend some money on Supra when there's a connector involved, seems to be where they shine.
