Better/best fullrange nearfield speakers?

SoundLabs, for real. I sit about six feet from my M645s and they are great. You just need space behind them. 

My good friend has a pair of U745s. He is also sitting about 6 feet away. Amazing sound. 
In your budget I think you could swing a pair of M545s and sit near field. It’s important to size based on room volume however. 

Not sure it this is spot on but the Revel Ultima Studio IIs were amazing in near field.  That is how I demo'd them at the Harmon Store.
