“These things improve clarity without causing brightness. Bigger soundstage, more precise imaging. Pricey but worth it. I am slowly replacing other footers with these throughout my system. I also use Isoacoustics products under both pairs of my Martin Logans with similar improvements.”
“Worked very well under my preamp which already sits on a sand platform.The tubes were actually continually being rattled loose when playing bass heavy music.Problem solved.”
“I purchased these to sit under my DAC and heard improvements in the width and depth of soundstage, improved intelligibility of vocals, and more precise imaging. Recommended!”
