S3 Isolation Base

The S3 Isolation Base was designed to obtain more of the performance of the M3X2 combined with the cost effective design of the R3X.

Product Features

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 E1 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.

The S3 Isolation Base is produced in two standard sizes and is available in a black or silver finish. Each size can be purchased with any of our different footer options to optimize performance for all components.

  • Broadband noise reduction systems maximize performance
  • Highly effective on wide range of surfaces and structures
  • Low-profile compact design minimizes space requirements
  • Standard sizes ensure full system integration
  • Can be use on any existing surface
  • Integrates directly into HRS Audio Stands without modification
  • Easily modified to optimize performance for different component types
  • Exceptional performance, great value

Every HRS Isolation Base model series can be set to either transfer and dissipate energy coming to and from the component or isolate the component from the supporting structure. Each HRS Isolation Base includes either our Broadband Isolation Feet (SF2 & SF3), our Extended Low Frequency Feet (LF2 & LF3), or our Bi-Directional Noise Reduction Feet. The selection of the footer type is made to optimize the performance of each component. You can also adjust or change the footer type on each isolation base at any time to keep your system at peak performance. Please consult your local sales representative or HRS to make final footer selection to optimize performance of your system.

SF2 / SF3:  HRS Broadband Isolation Feet – Isolates components from below 20 Hz to above 40k Hz. Excellent starting point for tube amplifiers, tube pre-amplifiers, DAC’s, phono pre-amps, and many turntables.  Select proper component range from chart below. For large amplifiers and turntables, please contact HRS for custom settings.

LF2 / LF3:  HRS Low Frequency Feet – Isolates component from below 10 Hz to above 40k Hz. Use for non-suspended turntables and when subsonic content is present and presents a potential feedback issue with the system. Also used for custom applications where they provide sonic benefit. Custom setup required for each component.

G7:  HRS Bi-Directional Noise Reduction Feet –  Transfers and dissipates energy coming to and from the component. Used for solid-state power supplies, power conditioners, tape machines, vacuum pumps, solid-state amplifiers, and solid-state pre-amplifiers. These can also be used if you prefer to not deal with different load ranges or where the use of chassis noise reduction products is not desired or possible. The HRS G7 feet do not have any load limit and can be used for any component. 

"The S3 is manufactured from a complex HRS plinth construction technology that increases the plinth performance to near reference level status. The new S3 plinth combined with the cost-effective assembly architecture derived from the lower price R3X makes the S3 an exceptional performance value."
