Bases

These isolation bases have been highly acclaimed even when used with other manufacturers equipment supports and are especially beneficial under turntables and CD players. The flagship M3X Series bases are based on granite embedded in a one piece aluminium tray separated by the HRS proprietary polymer. Underneath the aluminium platform are four round aluminium feet isolated from the base with a compliant polymer. The load range of the isolation base is optimised to give maximum resonance control and 4 different grades of these feet are available. These can be changed easily if the equipment on these bases changes.

How they work



They eliminate structure borne vibration and dump chassis noise that usually emanates from the transformers that are in all electronics. The result is one of a far more transparent sound, less high frequency distortion, allowing more detail to be easily heard. This results in a bigger sound stage and a more natural, less hi-fi presentation. The maximum benefit of these platforms is realised when used in conjunction with any of the HRS frames but they are very beneficial when used on top of other high quality equipment supports or indeed as free-standing amplifier isolation supports.

There is a new foot available for all the HRS bases called a G7. This is a solid design and is based a grounding principles rather than isolation. Ideally suited for amplifiers which have output devises mounted onto the chassis, solid state pre-amplifiers, and entry-level CD players. Because of its solid design, it can support any weight. Please call for advice on the application of the G7 compared to the compliant SF-2 isolator foot. 

There are six sizes available in the M3X2 Series from 19"x 14" to 23"x 21".

Custom sizes and isolator loading arrangements can be made to special order – please phone for details and a quotation.

M3 Isolation Base

The S3 Series Isolation Bases are designed to go with the SXR frame system (see above) but also can be used with the MXR frame where there are budget restraints. This offers a good proportion of the performance of the M3X Isolation Base but at significantly reduced cost. These are constructed from an aircraft grade aluminium surface and a multi-part aluminium ‘tray’.

S3-1719 Isolation Base £2245
S3-1921 Isolation Base £2395

Load Ranges for 1921 size:
ORANGE 0-11.5 kg
RED 11.6-20.6 kg
GREEN 20.7-38.7 kg
BLUE 38.8-70.5 kg

Please call for loading on 1719 size bases.

Custom sizes and isolator loading arrangements can be made to special order. Please phone for details and a quotation.

S3 Isolation Base

These isolation bases are similar in construction to the S1 Series bases but the surface is made from wood as opposed to aluminium. They offer a good proportion of the HRS effect and are a more affordable way of getting into the HRS isolation system.
