Design & Build
The CENTER STAGE ULTRA TT combines Critical Mass Systems’ thermodynamic approach to vibration management with a height-adjustable footer body. More than 30 damping contact points of varying dimensions are tuned around the footer’s materials, mass and geometry.
Its adjustable construction allows the supported component to be precisely levelled while maintaining the intended mechanical interface with the supporting surface. Optional adapters expand compatibility with components requiring a specific connection method.
System Pairing
The ULTRA TT is particularly well suited to turntables and other components for which precise levelling is important. It can also be used beneath digital sources, preamplifiers, integrated amplifiers, power amplifiers, power supplies and power conditioners.
The footers should be installed on a stable, flat supporting surface with other aftermarket isolation accessories removed. Critical Mass Systems recommends allowing 7–10 days for settling and approximately 14 days before making a final performance assessment.
