A:AnswerI personally do not use the cinnamon for my eARC. I only use it for my 4K 120hz gaming consoles. For my eARC I use the one that is one step down called forest with my Sonos system and everything sounds perfect. The cinnamon in my opinion is overkill but, it definitely wouldn’t hurt.
A:AnswerFrom my personal experience the color on a quality 4k tv and the audio quality. I personally play alot of Blueray audio and video through them into my 9.2 chanel reciever and it sounds and looks awesome. I personally stopped at the Cinnamon line I felt it was a sweet spot for performance to dollar. If I could afford it I would try some higher priced ones.
