I agree with you yet they are super expensive. The setup you showed I googled it and the price for that setup was 7k. I don't doubt they will sound great considering they are made by Yorkville. I would love to find a place where I could hear that setup.
That's way out of my price range for me unless I were getting gigs like Bob Carpenter. His starting price last I know about is $1,500.00 and it goes up from there. He even mentioned possibly getting to do a wedding for 9k. I could see myself buying such a system if I were getting gigs paying what he is getting and as busy as he has been over the years. That's not me. I just want to hear them for myself. Maybe I shouldn't go to listen to that system because all I'll be thinking of is how can I get to buy that system or steal it so I can say it's mine. LOL.
