Roller Blocks

Key Features

1. High-Precision Isolation Mechanism

Roller Blocks use a ball-and-cup design that allows micro-movement.

This decouples your audio component from external vibrations.

Ideal for high-end systems where even tiny vibrations matter.

2. Dramatic Noise Floor Reduction

Reduces mechanical noise transferring into amps, DACs, CD players, and streamers.

Helps achieve a quieter background and more refined sound.

3. Enhanced Clarity and Resolution

Improves micro-detail, instrument separation, and transparency.

Provides a more holographic soundstage with cleaner imaging.

4. Superior Low-Frequency Control

Tightens bass response by preventing vibration feedback.

Helps maintain stable and controlled low-end performance.

5. Free, Natural Movement

The rolling action allows the equipment to self-level and dissipate energy.

Prevents vibration buildup, improving long-term stability and sound purity.

6. CNC-Machined Construction

Made from high-grade metal with precision tolerances.

Smooth, polished bearings for frictionless operation.

7. Universal Compatibility

Can be used under:

DACs

Tube and solid-state amplifiers

CD players

Streamers

Preamp units

Power supplies

Turntables (heavy plinths recommended)

8. Set of Three or Four

Three pieces for perfect leveling on uneven surfaces.

Four pieces for heavy or oversized components.

Description

Foundations Isoball is Inspired by the RollerBlock

A one-stop solution to isolating your bookshelves and electronics.

The Isoball lends a nice roundness and density to the bass and midrange. It generally leaves the top end intact and does a little to add focus and improve microdetail.

Just as the cera ball, this can simply be placed under your electronic equipment, such as CDPs, pre-amplifiers and Integrated Amps or can also be placed under your stand mount speakers, offering another level of isolation.

Silicon, cork, and other polymer pads tend to sound muffled and slow, robbing the music of its detail and accuracy. The Isoball keeps both intact.

The isoball has 3 parts. An aluminium base cup, An Aluminium top cup and a Tungsten carbide ball. The combinations of these 3 composites work in harmony to produce the best results. Many hours of testing allowed us to fine-tune the cup curvature and the manner in which the ball locates inside the aluminium cup.

The Foundations isoball comes with an isofelt inlay on the base

How to set up the rollerballs

In general, I’d say the following rules hold:

1. Ensure that you place the blocks under the heavy parts of the equipment. Put more blocks on the side (front/rear, left/right) which have more weight. Adjust them to get the centre of all your blocks matching the centre of gravity of the equipment.

2. Placing blocks more towards the periphery gives a calmer & melodious but also less open/dynamic sound. Moving them closer to the centre of the equipment will increase the openness and dynamics (including transients) but reduce clarity and microtones. Adjust accordingly to get the right mix.

3. Optimise the placement under the source (CD player) first and then work your way towards the power amp. To begin, place all close to the stock feet and then, starting with the source, start experimenting. Once you’ve optimised the placement under the source, move on to the pre. Once you’ve done all, you may want to do one more iteration if you are finicky.

Also, check that each block is under the flat bottom of the equipment. Don’t put a block under a screw or uneven surface. Once kept, shake the equipment a bit and see if all blocks are showing equal relative movement between the upper and the lower block. If it’s not free enough (all of them), you may need more blocks. If one/two blocks show less free movement than others, you may need to move the other blocks towards these blocks to share some of their weight.
