A/V is subjective. I can tell you with certainty that the vodka cable delivers a sharper 4K image on my oled than the carbon, but the differences are minor. Comparing the vodka to a cinnamon cable, the differences are far more obvious. I see less fine detail in the image. Things that were sharp using the vodka when viewing from several feet away are less sharp using the cinnamon, which also had several small artifacts. This isn’t the difference between a 70% and a 99% PQ. It’s the difference between an 87% and a 93%. Put another way, if you pay more at the pump for high octane gasoline because you understand that it translates to better acceleration in your vehicle, then the vodka cable is definitely for you. With respect to audio, all I can say is the difference there becomes much larger. It’s like changing to a higher bit rate when listening to compressed music or going from 120 to 140 watts on a receiver: more of the audio track seems present and arrives with greater nuance. I am not b.s.’ing and I am not selling cables. Anyone who claims there is no difference between HDMI cables is ignorant and trying to sound intelligent. The claim that 1’s and 0’s either arrive or don’t arrive simply doesn’t hold water. That’s an oversimplification made by someone who clearly does not understand how signal degradation works. People seem to have no trouble understanding why Apple makes superior products as a result of the materials used and workmanship involved—if a CPU runs cooler and more efficiently, then it lasts longer. People understand when they look at a Sony tv, that it may not be as bright as a Samsung, because Sony is running the led/lcd display at 40% of maximum output, where as the Samsung is running at 90%. One is going to be more prone to have problems than the other. You pay for what you get, folks, and you get what you pay for. Good luck.
