“The S1 Isolation Base was derived from our reference level Isolation Base. It has the same primary isolation stage combined with a new innovative plinth construction that achieves a high level of performance at a lower price point for our customers.”
-Michael Latvis
Chief Engineer
Harmonic Resolution Systems Inc.

The S1 Isolation Base is a highly innovative design that eliminates noise, revealing a new level of musical performance. It is manufactured from four different materials including a proprietary resonance control stage with billet machined aircraft aluminium trim and inlay. The S1 load range is matched to the component weight for maximum performance and can be modified in the future to preserve initial investment. This is a unique product that offers audiophiles industry-leading performance at a fraction of the price of our reference level designs.

The S1 Isolation Base is produced in two standard sizes. Each size can be purchased in any of the three different load ranges to optimize component performance.

If one of standard sizes or load ranges does not fit your needs, HRS offers hundreds of custom designs in our M3 Isolation Base product line including custom designs for all large turntables and amplifiers. Please contact your local sales representative or Harmonic Resolution Systems for assistance with custom isolation bases for your components.
The broadband noise reduction system in the S1 maximizes performance and is highly effective on a wide range of surfaces and structures. The low profile compact design also minimizes space requirements. The S1 Isolation Bases Integrate directly into the HRS audio stand frames. (S1-1719, S1-1921 sizes)
