Really hard to provide any meaningful advice based on the info you have provided other than you seem to have a case of audiophile merry go round syndrome.
Other guesses I can venture based on nothing but seeing and reading comments in places like this; speakers are too big for the room, speakers are not positioned properly, cannot breathe, too close to walls etc. System is set up on wrong wall/not the long wall, room is acoustically challenged and nothing has been done to mitigate.
There is no reason that system is not creating beautiful sound other than above.
