Better sound quality with customized dampers with back of 4.5 mm air soft gun steel balls

[pecado]

Have you used attenuators under your computer and headphone amplifiers? I have had Symposium Acoustics Rollerblocks 2 with the best grade 2.5 balls. However, I made a physics model and calculated the optimal volume for 4.5 mm airgun balls and got even better sound quality.

Under the feet?

Here I have about 1000 steel balls (total 3x1000) per bag
with pillow. The bottoms of my device are very stable so for the best contact I skip the legs: They are not needed.
