The Stillpoints Ultra 1 S is the latest evolution of the highly regarded Ultra 1 V2, introduced in early 2024. It builds on that success by delivering an even more natural and open presentation. When recordings allow, sound becomes clearly more three-dimensional, with improved depth, space, and realism.
Sonically, the Ultra 1 S offers exceptional high-frequency extension. In fact, it delivers the most extended and refined treble performance of any Stillpoints isolator to date. As a result, fine detail, air, and spatial cues emerge with greater ease and accuracy.
The Ultra 1 S features a single technology pocket with an attached hard hat and a durable black powder-coated finish. A 1/4-20 threaded hole in the base allows secure mounting in a wide range of applications. In addition, it can be paired with the Ultra 1 Bullet Spike (sold separately) when required.
For added flexibility, the Ultra 1 S can also attach directly to equipment using the appropriate Stillpoints adapters. Therefore, it integrates easily into many systems, from source components to amplifiers and accessories.
