For the benefit of the community, I am not an "anti-isolationist". In my discourse I do not speak to the topic of isolation of analogue front ends, as I do not use analogue source. I presume it would be a very important part of the analogue setup, and were I using vinyl I would aggressively pursue the comparison of various devices and methods to determine their efficacy, as I have with other methods for speakers, components, etc.
I have done many comparisons of various isolation devices for components, and choose to focus instead on the electronics. My time is better served by building systems than waiting for burn in and placing isolation devices.
Imo, the principle benefit of footers, spikes, stands, etc. for speakers is the elevation of the speaker, not the materials used. Some industry members would disagree; so be it. That is why I have 2 dozen hard rubber hockey pucks on hand to elevate subwoofers, speakers, etc. BTW, what does Pass Labs use for "isolating" the XA200.8 Mono Amp? A very hard rubber footer that has similarity to a hockey puck.
As can be seen, I don't fawn over every proffered improvement the industry promotes. Disagree? Great, build systems your own way. :)
