STILLPOINTS ULTRA I E

The Ultra I E delivers an exceptionally natural sonic presentation, unlocking a more three-dimensional soundstage when the recording contains these qualities. It offers the most extended high-frequency performance of any Stillpoints product—and arguably any isolator available today—ensuring unmatched clarity and detail.
KEY FEATURES
Natural, Dimensional Sound
Provides a highly realistic and immersive listening experience, enhancing depth and spatial accuracy.
Unrivaled High-Frequency Extension
Sets a new benchmark for high-frequency performance across the Stillpoints range.
Durable Construction
Finished in a tough black powder-coated exterior, featuring a single technology pocket on top and a ¼‑20 threaded hole in the base for secure mounting.
Height Adjustment & Performance Boost
When paired with the Ultra I Base (available at a discounted price when purchased together), you gain precise height adjustment for leveling components and a 20–25% improvement in performance per isolator. This enhancement comes from isolating the Ultra I E from the support platform, eliminating material influences and allowing the isolator to perform at its absolute best.
