CATV isolators almost a must - cable and dish companies often use separate grounding (as well as roof OTA antenna) for safety reasons, and as result unavoidable ground loops and hum of various degree. So I would install it no matter what. The only issue is dish, powered by receiver - then you will have to install separate power supply for your antenna, as isolator will break low volt signal coming from receiver to dish. Satellite service provider installed separate power for me for free by my request.

I have another observation - most UHD players and even OPPO 105 have separate outputs for HDMI video 4K and audio. In theory it is done to support older receivers/processors, which do not have 4K pass-through. In practice it has a lot of other applications and implications, but in my experience separating audio signal (it does send video as well, but lower resolution) from video yealds a touch better sound for concert disks, May be it is a placebo effect, dunno, |
I have just now found few good quality HDMI cables and ordered amazon High-Speed HDMI Cable. The cable is capable to support bandwidth up to 18Gbps. |
I have excellent results with the Audioquest Carbon HDMI Cable, one of their newer HDMI cables controlled for directionality and with silver content in the connectors. I am using the Carbon with my new LG HDTV and LG Blu Ray player. Spectacular picture. I am also using contact enhancer on the pins and ground. |
