Thank you all for your responses. This stuff is confusing. I have a pretty decent system and I want to get this best out of it. I initially went audio out via optical from the OLED tv to the A/V processor/. That worked okay. Now I am using the ARC hdmi from the OLED to the ARC HDMI of the A/V processor. I have Magico S5 for the front speakers powered by Mac 611's, Mcintosh for the center and two Mcintosh XR200 powered by MAC 452 for the surrounds. Two Subs are SVS Ultras. I noticed an improvement over the optical connection using the ARC via HDMI The ARC made a difference in the low end and the dialogue is improved through the center channel. The video quality of the LG C9 is the best I have ever seen. However if I can improve audio and or video I am willing the dish out the $1,000.00 for the Zappiti streamer. Do you people think it would be a waste of money or do you think I would see a improvement in audio and or video going from the Zappiti via HDMI to the A/V processor. Sorry for being redundant but I am ignorant when it comes to the tech stuff and sometimes don't understand the responses on this forum.
Best regards.
