My TV needs to be repaired again but my set up is now a properly set up HiFi with Apple TV 4K, LG C1 display and Bose 600 soundbar with 7.1 channels experience *it is 3.0.2 with virtualised surround speakers. If you get to this level then you will realise the difference between lossless audio channels and what digital compression does to the sound. I have a conditioning power strip and a dc block device to reduce interference. I plan to get a more robust filtered strip and shielded cables next month. Now working up to a higher quality HDMI cable from heavy 8K Zeskit Maya to stylish, slim and light Spigen ArcWire and QED, now looking to move into a more premium silvered copper HDMI cable for the audio eARC function.
