So you connect everything to ysp2700?
I think there are some about, the Sony HT-X8500 soundbar is eARC I believe, but it only has 2 hdmi ports one of which is the output. Quite cheap as well but not sure its as good sound wise as the ysp2700, which was priced considerably more.
I have my PS4 and Switch into the 2700. Xbox is now plugged into tv as it has the auto low latency mode and variable refresh. Sky box and Apple TV are into tv too. Tv is connected to 2700 and uses arc for everything connected to tv.
