Great informative thread this. I‘ve decided to join the E9 club. After doing much web research on E9 vs CX, I could find no compelling reason to pay more for the newer model. So, just ordered the LG E9 65 inch via Richer Sounds to replace our much loved LG E6 55 inch. Sacrificing 3D, which is great but rarely used due to a lack of content, for the extra screen size goodness in general viewing via Sky Q, Apple TV and Netflix. In terms of sound quality, the integral speakers on the E6 were good enough for us, so I’m hoping the same is the case for the E9.
Looking forward to it. Now to relocate the E6 somewhere else in the house, which could be a challenge
