@yage , thanks again. I have no Wifi 6 compatible devices at this point. I will definitely keep your points in mind. As you recall the original conversation started with the query about sound quality (referring to continuous distortion level, not reliability). I have yet to be persuaded that a reliable wifi network distorts audio more than ethernet. I see no way for that to take place. If there are specific routers with superior clock accuracy or electric noise control which impacts the bit stream I remain curious (but that would not be specific to wireless vs. ethernet).
Cheers!
