Glory I have had many different footers on many high end speaker systems. The magico q5's come with extremely well made and no doubt expensive spikes. If you think brass is the answer by all means enjoy. I have had spikes on tt's, on all types of stands, etc., don't like them. Don't believe in their "science". Here's an article that makes my point. Think as you wish, I prefer real science, engineering and independent thought.
Which footers have you tried? The Magico footers are aluminum no doubt.
I am a man of "science" as well. One of the central elements to any science is experimentation. You should try the Starsound products (stands not the footers) and report back. It is a company with a team of engineers involved. No soggy pseudo-science. BTW, the SS products do not work by "isolation." Your panties are bunched up in part due to semantics....
