New Arrival : Center Stage Ultra TD

Center Stage Ultra TD

Critical Mass Systems is proud to announce the launch of the Center StageUltra TD footer made for electronic components. Critical Mass Systems is strictly focused on the principles of thermodynamics applicable to High End Audio. High End audio presents a range of challenges wider than those found in any other industry where vibration is a barrier to performance. Our mission is to suspend disbelief, meaning; to provide the means to which electronics can make reality come out of your loudspeakers.

After Reviewing our approach laid out in the Approach section, you now understand that there is no such thing as isolation in a listening room because sound is vibration and sound is everywhere in a listening room. Given that vibration is present on all sides of a component, you cannot build a vibration firewall in a listening room and there is no such thing as a vibration diode in a listening room. Furthermore, electrical systems resonate internally. Mass stores energy. The misinformed are kept unaware that a vacuum is the only thing that can stop vibration and, there is no naturally occurring vacuum in the universe. You can’t solve a problem until you understand the problem. The problem is that vibration is everywhere in a listening room and you can’t stop it.


  • Diameter: 2”
  • Height: just over 1” (51mm x 25mm) +/- 5 microns
  • Weight: 6 ounces / 150 grams. There is no weight limit

We named this footer “Ultra” for a reason. In the Ultra Series, the damping “sweet spot” achieved using 30+ touch points is so finely tuned, so accurate, so perfect for the weight, dimension and materials used to fabricate the foot that placing 1 set under your front end component is, well, amazing.

Amazing means an unexpected expansion of the soundstage in width, height, depth and image definition. Expect improvements in vocal expression and realism, and instrumental timber, separation and weight. Expect to hear new musical details previously obscured by an elevated noise floor. Expect greatly improved front-to-back layering and image stability. The bottom line: Expect your system to bring you closer to the original real event as it was originally recorded.
