I'm less impatient than you seem to be. I decided to slough through and I kept my Bushmaster on constant burn-in. Guess what -- I think it paid off! Ten days into it, the Bushmaster finally came into its own. It never sounded better. Now when I plug the Caiman next to it, the Caiman sounds like fingernails across the chalkboard in comparison.
My advice -- give it a few weeks to burn in. There might be ups and downs from day to day, but bear with it. If after say two weeks of constant burn in you still don't hear improvements, well then perhaps it's beyond help.
