I understand your point. I just can’t spend that much on footers etc... They (IsoAcoustics) did improve my system’s sound nicely and I am very happy with them. They also helped my speakers feel far less tippy and secure to the floor which is a nice plus.
Perhaps I will someday find some used Podiums priced right and try them. They come up rarely and when they do they are still out of my price range ☹️.
