My 2021 LG TV is connected to my Arc via eArc (also have two Sonos 1 Surrounds and a Gen 3 Sub) which is giving me amazing sound including Atmos and it does passthrough of Atmos from any devices connected to it.
Because of the configuration of the room, the TV and Arc are at some distance from the rest of the AV equipment and there is currently only a single lengthy HDMI cable between the TV and the area where that equipment is stored.
To avoid unplugging the HDMI cable and swapping it between a Cable Box/Apple TV and a UHD DVD player my options are:
- upgrade my AV Receiver to one that does Atmos passthrough and thereby keep the single HDMI cable (connecting the boxes to the Receiver); OR
- chase additional HDMI cables so that each box can connect directly to an HDMI input on the TV.
Does anyone know whether “double passthrough” of Atmos dilutes quality? In other words, if I connect my boxes to a new Receiver which then connects to the TV which then connects to the Arc, will that be less quality than having a Box connect directly to a TV?
