Ultra I E

Description

The Ultra I E is Stillpoints’ compact isolation footer designed specifically for audio electronics — DACs, preamps, CD transports, phono stages, and amplifiers.

At its core is a single technology pocket containing Stillpoints’ 4th-generation ball stack: precision ceramic bearings arranged within a stainless steel housing to both isolate your component from external vibration and evacuate the micro-vibrations generated internally by transformers, capacitors, and circuits.

This two-way filtering is what separates Stillpoints from conventional isolation. Most products only address vibrations in the audible frequency band (20Hz–20kHz), which can shift tonality. The Ultra I E operates above 20kHz — removing noise without altering your system’s tonal character.

What you’ll hear

The Ultra I E delivers a more natural, three-dimensional presentation. Backgrounds become quieter, transients gain speed and definition, and the soundstage opens with improved depth and focus. The effect is subtractive rather than additive — removing the subtle haze that vibration introduces so the music emerges with greater clarity and presence.

At $240, the Ultra I E outperforms the larger (discontinued) Ultra II V2 and approaches the performance of the Ultra 6 V2 at a fraction of the cost.

Configuration

The Ultra I E features a durable black powder-coated finish with an exposed technology pocket on top and a 1/4-20 threaded hole in the base.

For maximum performance, pair with an Ultra I Base. This provides fine height adjustment for levelling and delivers a 20–25% improvement in isolation by separating the filter from the support surface. Available as a discounted bundle.

Although the Ultra I E can also be attached directly to equipment using Stillpoints adapters, the optimum way to use the Ultra I E is with the Ultra I Base placed directly in contact with the under side of the component. Start with three units and move them around to reach the most effective location. Once you have established where they make the best improvement, one can add a fourth or fifth to further the absorption of the micro vibration that creates the haze.

Note that when using the Ultra I E with a Rail Grid or X Grid (as part of an ESS Rack or Ultra ESS Rack) or with Component Stand SS, you do not need an accompanying Ultra I Base. However, when used on a shelf, the addition of an Ultra I Base will add an additional 20% to the performance of the Ultra I E.
