@cleeds i never said that they are the same thing. I said that “streaming” from Qobuz, Tidal and others are not true streaming. You download the song in its entirety, and then playback from a cache. That is why simply why everything that “improves” Ethernet just doesn’t, and cannot do. Even OP said that the manufacturer said it doesn’t do anything. if you don’t believe me, look at their support sites and you will see what they say for yourself.
No one “challenges”, they just put a bunch of garbage out there that is not true. And then you give them enough rope to hang themselves… it is very sad that this is the state of the industry.
