Borrow a high end source from a local audio retailer to determine if the source is the problem or the room. I have speakers in the same family the JM Labs mini utopias with a REL sub. I am using an older Cary 303-100 player and it's a good match. I am in the process of upgrading my player to Modwright Sony 999ES with the full mod. Total cost would be around $2,600 since you can find the players for about $500. Just another option. Check the latest Modwright review
