Funny that you just posted. I was reading another thread and came across some comments on Wire World HDMI. If the comments are accurate, it appears that the Wire World DNA Helix design is so good, that their normal Starlight 7 cable (silver-plated copper) measures at 28 GBPS, which is interesting because the HDMI 2.0 spec for 4K tops out at 18 GBPS. If this is true, then I would say that there would be absolutely no difference between the Silver and Platinum series HDMI cables. If you wanted to look for improvement, you might try researching if other transports are better than PS Audio. Reducing jitter and improving system clock are paramount in sending PCM/DSD to your DAC. It looks like your PS Audio player is very well engineered. Maybe Aurender A10? Or maybe get an Oppo BDP-103 and have the linear power supply and OCXO clock mod done by Oppomod.
I'm posting the referenced link and comments below:
"But with the 8801 I and others positively do hear improvements. More specifically with the Wireworld "DNA Helix®". There is no shortage of wire marketing jargon and snake oil. And I hesitated to say anything because it opens up a massive can of worms. But at the end of the day, their patented approach makes this "DNA Helix®" over 50% faster bandwidth than any other HDMI wire no matter the price. Their copper Starlight 7 measures 28 GBPS. No matter how much money you spend for lower resistivity, it's only going to speed it up 1 GBPS. So their Copper http://www.wireworldcable.com/hdmi-2.0-cables.html sounds the same to my ears versus their Silver versus their Platinum (the price skyrockets). I have not repeated the listening session with the 7702 or 8802. So maybe their jitter reduction techniques make it so it no longer matters. When I sell them, I mandate people send them back if they don't hear or I want them back. A total of 2 came back. When they don't hear a difference I say great, they saved money."
