Solidsteel 5.5 rack: To fill, or not to fill?

increase its weight.

that's easy just change the shelving using Corine or something equivalent

Change vibra pods to bdr.Big differance in sound.yes i have h6 rack,fill it to give it more stablization(vibrations)and mass.

I have noticed a difference and fill my stands 100%.
BTW; I also own a solidsteel, and use many starsound products.

Star sound Micro-Fill. Because the steel beads are uniform in shape, they'll compact more allowing the stand to only be half filled.
I have them in my GPA stand and ampstand.

Thanks for your responses. After having a good, really helpful conversation with Robert at Starsound I decided to fill the posts of the Solidsteel w/Micro-Fill, trade out the OEM spikes for AudioPoints, and get aluminum, or cold rolled steel plate to cover all five of the MDF shelves. Hope I don't have trouble finding a fabricator to make the damping plates.

I'll report back with the results. NB: My components are currently on a heavy, wrought iron console with stone shelves, so I won't be able to compare how the system sounded before the tweaks to the Solidsteel and after.
