Hi, I note no one has mentioned the critical mass systems centre stage footers. I use them on my full system Unfortunately they take 10-30 days to ‘settle in’, so A/B comparisons are out.
Initially I went on reviews and faith: I bought and reviewed the speaker footers on my active Kii 3 + stands at the manufacturers request - see what’s best forums if any interest. The results were astonishing enough to convince me to do all the electronics including the NB.
I never owned stillpoints, but at one time I had borrowed and used one set. They made the system sound hard and ‘metallic’. Have not tried them again. For full disclosure, I should say that was 15-20 years ago, early days, probably they are better now.
Now I am pretty much sold on these centre stage jobs. Even though they are not cheap in themselves, I was never able to afford the big critical mass systems gear though I always wanted it… so when these were introduced it was a no brainer. According to the designer they are the culmination of his life’s work with vibration control.
