Moreno Mitchell has posted a review of the Stillpoints Aperture acoustic panels ($650) at Stereo Times. His conclusions:
“The improvements brought on by the Stillpoint Apertures in my humble opinion are stunning and are hereby a must have. This review would be unjustified if I did not mention the cost factor. What the guys and gals at Stillpoints have done with regard to design, engineering and manufacturing of this product is an asset to the hi-end audio industry. Remarkably, what makes an even better story is their $650.00 price tag.”
