People having a right go at you here in the comments. If it works for you, then it works for you. If not, then your dissatisfaction is part of your education on the matter. My first soundbar, a Hisense, was initially satisfactory but as time went on, I was increasingly dissatisfied to the point where I got a Q800d and I've been happy ever since Sometimes the first time works out, sometimes you need to get burnt so that you learn

My Q800D is affected by this. It powers on and says it's connecting to HDMI ARC over and over again. It then stops and is unresponsive to the controls on the soundbar and the remote with no audio coming from it.. Spoke to Samsung, they want me to take it to a repair shop, not ideal having to haul a massive soundbar around..

I can say the same. Currently own Arc Ultra + Sub 4 + Era 300s.  Previously owned Q990D and Q990B.  The Samsung is amazing value at its price, but the Sonos set just sounds cleaner and gets to high volumes without straining. It doesn’t ever  feel harsh or overworked.  I would say for its money - Sonos is 3 to 4 times more expensive but is NOT 3-4 times better, but there is a difference in quality for price.  Both are terrific - and get what your budget allows - would you agree?

My issue with the Sonos arc ultra is that the entire setup with the 300’s and gen 4 sub costs 3x what you can get the 990D for and it is in no way 3x better. There are some things the 990 even does better. The Sonos is definitely better for music tho
