The S3 Isolation Base is a highly innovative design that eliminates noise, revealing a new level of musical performance. The S3 is manufactured from seven different materials including a proprietary resonance control stage with billet-machined aircraft aluminum trim and a plinth construction that increases plinth mass by seven pounds. The S3 Isolation Base is configured at HRS to optimize the performance of a specific component and can be changed in your home to optimize the performance of a different component at any time.

The 51 lb S3 (1921 size) plinth construction is manufactured by laminating in a vacuum press alternating layers of high-density fabric reinforced resin and non-magnetic stainless steel plates on both sides of a decoupled mass energy dissipation core system. The very top skin of the S3 plinth is the same high-quality, scratch-resistant surface layer used in the R3X and E1X Isolation Bases, providing an identical cosmetic match in systems that utilize different isolation base models in the same system. Encompassing the S3 is a billet-machined heat-treated aluminum alloy stiffening trim which is finished to exacting HRS standards for cosmetic elegance. The low profile (3-inch height) design also minimizes space requirements and keeps the visual focus of your system on the components you have selected.
