The Vodka cable has better connectors and appears to provide a clearer signal. I started with Chocolate Audio Quest HDMI cables and moved up to Carbon and then to Vodka in keep areas for my home theater setup. The biggest improvement was in sound quality with less improvement in picture quality. However the improved picture quality is noticeable on my 65" SONY 4K TV. I found the best place to start is the connection between the DVD Player and Receiver. I currently have Vodka cables from the DVD to Receiver and Receiver to the TV. All others are Carbon cables. I also noticed an improvement during my initial upgrade from Chocolate to Carbon too.
