Just as components, including all cables, are system dependant, so are tweaks.
Some of the tweaks I've found to be helpful and have heard immediate improvements were one-piece SS cones for my spkrs and isolation devices between the spkr. modules. Other tweaks are subtler but a combination of them all helps with the overall presentation. The only way to tell for yourself is actually try them and you can go the DIY route for a quick & relatively inexpensive attempt.
Even with all the tweaks available, if your room isn't maximized, you won't get nearly as much benefit & the very first tweak I'd suggest is spkr. positioning. I spent 4 months optimizing my spkr. placement, just to let you know it takes more than 15 minutes to do this, although I could've done it in less time.
