@david_ten I never tried three with the Merlins, as these speakers have a small crossection that gets tippy with three points. However, I have used up to five Ultra 5s and Ultra SSs under electronics and turntables with incremental improvements. Same thing with Starsound Audiopoints under an Esoteric K-01X CDP, where I use six Audiopoints into a Rhythm rack. BTW, even after all of that, the Esoteric benefits from a Stillpoints LPI record weight at the center of its aluminum top plate!
