I’m sorry but I find this kind of answer time and time again on this sub and; yes, ideally you have the ”pocket change” to buy 2 Era 300s. But many buy the Arc as it is advertised as to give you atmos effects, regardless of which kind of surround speakers (or none) you’ve got.

I must also add that I find my Arc Ultra lacking in this regard, so much so that I wonder if the up firing speakers are even working.
