CMS - Critical Mass Systems


The Foundation for Great System Performance!

Audio component racks fundamentally shape the quality of the signal that comes out of the loudspeakers. A good rack will make music sound more “realistic” as vibration from the loudspeakers, the components and the rack disappear, revealing the inner detail of the music.

Critical Mass Systems utilizes the best modern machines and tools combined with precision craftsmanship to produce an amazing product. Our systems allow your component can retain the “sound” that was intended, revealing the inner detail of the music.

Constructed from proprietary internal vibration materials, our unique Dual Zone Damping System helps the filters manage vibration so that the signal processed by the electronics and analog devices sounds life-like and real when it the comes out of the loudspeakers.
