P.I., something to consider as you begin this process is that many tweaks make your system sound different, but not necessarily better. That said, I second BDR cones as a good place to start. Enjoy!
Next tweak to buy?
I have a descent stand and I want to start trying tweeks but dont have any experience with any of them. I have been looking at feet, pads, and the isolation devices that you put on top of and below your components. What do you recommend to try first? What materials and brands are best? Thanks
