Sizing up

The weight of your speakers is crucial in determining the right load cells for perfect isolation within the audio waveband. Our carefully calibrated Loadcells ensure the ideal spring-mass load, allowing your speakers to “float” and achieve comprehensive isolation from external vibrations. Once this balance is achieved, you’ll select a platform that fits your speakers as shown in the diagram. If there is a slight overhang at the front or back, this may be acceptable. For speakers that don’t fit any standard platforms, we offer a bespoke service to create a custom stand that perfectly suits your setup.

Key Benefits You’ll Love

Unrivaled Clarity:

Using 99% air insulation (with bare copper strip conductors in thin-walled PTFE tubing), the cable minimizes dielectric distortion, improving signal purity compared to conventional cables with denser insulation like PVC.

Handcrafted Quality

Bespoke cables made with precision for audiophile-grade performance.

Deep Cryogenic Treatment (EDCT)

The copper conductors undergo Enhanced Isolda Deep Cryogenic Treatment, which enhances transparency and neutrality, outperforming other materials in clarity and detail. Improved Soundstage and Detail: Users report a larger soundstage, precise instrument placement, and enhanced detail, with the ability to discern subtle differences in recordings, such as identifying distinct recording studios. The cable excels in bass extension and dynamic range.

Signal Interference:

The design reduces capacitance (25pF) and inductance (0.5uH), minimizing signal loss and interference, which contributes to its clean and vivid sound.

Description

Since the late 1940s, when the term “hi fi” was first applied to high-quality (high fidelity) sound reproduction systems, it has been conventionally accepted that the range of human hearing has an upper limit of about 15 to 20 kHz.

The signal used to measure this response is an artificially‐generated sine wave. However, modern research and long term experience working with High Fidelity systems now question this firmly held belief. Harmonically rich, highly transient, real‐life sounds extend well beyond 20 kHz; for example, the muted trumpet has a frequency response extending to beyond 100 kHz.
