Design & Build
The ULTRA GATEWAY brings Critical Mass Systems’ approach to vibration management into an accessible, modular equipment rack. Its natural stained Sapele structure incorporates sandwich damping around the contact points between each shelf and the supporting frame.
Aluminium-alloy feet, risers and top caps are combined with surgical-grade titanium spikes and connectors to create a rigid, mechanically grounded support structure. Its fixed dimensions provide predictable equipment clearance while allowing additional levels to be incorporated into a system configuration.
System Pairing
The ULTRA GATEWAY is designed for digital sources, turntables, preamplifiers, integrated amplifiers, power conditioners and other high-performance audio components that fit within its usable shelf dimensions.
Each level can be upgraded with a Critical Mass Systems Sapphire 2, ULTRA PLATINUM or ULTRA DIAMOND filter. Center Stage ULTRA TC, TD and TT footers can be added beneath individual components, while LS 2.25 footers may be installed beneath the rack to further enhance the performance of the complete support structure.
