Harmonic Resolution System SXR 1921-SBI-B

Silence the Noise. Hear Everything.

The Harmonic Resolution Systems SRX 1921-SBI-B is a precision-engineered vibration isolation base designed for serious audiophiles. By eliminating the mechanical noise that plagues even the finest components, the SRX platform allows your equipment to operate in its intended acoustic environment — free from the floor-borne and airborne vibrations that rob music of its detail, dynamics, and dimensionality.

Engineering That Disappears Into the Music

HRS isolation platforms are built to exacting tolerances using proprietary damping materials and constrained-layer construction. The SRX 1921-SBI-B is sized for a wide range of components — from amplifiers and preamplifiers to DACs and phono stages — and integrates seamlessly into any high-performance system.

What You'll Hear

• Lower noise floor with blacker, quieter backgrounds
• Improved transient speed and dynamic contrast
• Enhanced soundstage width, depth, and image focus
• Greater low-level detail retrieval across the frequency range
