Not really my place here, but would like to bring a few thoughts into the conversation.
Regardless of the good, better, or best performance from a footer, a large percentage of what you are experiencing with any type of footer, especially those located under electronic components; the principal equipment rack or speaker plinths totally affects their sonic outcome and your decision making.
Everyone forgets or never realizes that the equipment rack is the core component - the heart of every system.
The rack governs every purchase you make from now or until you decide to audition and purchase a racking system capable of higher performance.
Unfortunately, for most audiophiles, this is the least discussed piece of equipment in the system.
I would love to hear more about the rack brand, construction, or materials used when discussing footers, accessories, and sonic opinions.
Thank you for your time,
Robert
