bFly-audio was founded in 2014 by Reinhold Schäffer in Augsburg, a university town city in the south-west of Bavaria, Germany. For the past ten years we have been designing and developing our own products with great success. Mult-layer adjustment technology (MLA) is the offspring of our forward thinking and experiments over the period.

Technical Background

1.Vibrations and their negative consequences: Microphonics

Microphonics is the scientifically proven effect that currents and signals disturbed by vibrations will be adversely influenced. This is a law of physics. The outcome is an audibly more tentative and spatially less stable sound image. Devices affected by this include: analogue turntables, CD players, power supply units and amplifiers of all kinds.

Vibrations reaching mechanical devices like turntables and CD players have a deleterious influence on the sound, as there is a negative effect on the pick-up abilities of the stylus and the read quality of the CD laser.

2. Types of vibration

Ambient noise (also referred to as airborne vibration):

By this we mean the vibrations that travel through the air to the devices.

The cause of these are your loudspeakers, whose sound waves can cause a disturbance in your devices. One thing that can be forgotten is the oft-quoted “footfall” – who walks through a room while they are listening attentively to music?

Mechanical vibration (also referred to as structural vibration):

By this we mean vibrations transmitted through solid objects. These are vibrations whose effect on the devices is felt via the device support, i.e. the rack and what is underneath. The cause here is once again the loudspeakers, which transmit sound waves to their rack via the floor. If you have unstable flooring such as laminate, tiles or floating parquet (not fixed with floor screed), you should decouple these sound waves with absorbers.

bFly-audio is a manufacturer of vibration absorbers, adopting proprietary "Multi-Layer Adjustment Technology" (MLA) to eliminate vibrations and optimize laser pick-ups for accurate signal retrieval thereby reducing tracing errors by 90% and achieve natural sound quality beyond imagination. Manufactured in Germany, bFly-audio products can be applied to various audio components. Reduced air-borne vibration dwarfs microphonics so that full potential of source components can be exerted.

Multi-Layer Adjustment Technology (MLA)

"Multi Layer Adjustment Technology" utilizes selective balanced layers of different absorber materials -- Sorbothane, cork, natural rubber, etc. separated with a non-absorption metal layer (like brass). Products feature optimal adjustment to the weight of the individual High-end components by different variants (Adjustment). Each absorbent layer provides filtering of different frequency ranges, resulting in improved cumulative effect compared to single materials.

Sorbothane® is a proprietary, visco-elastic polymer, a material exhibiting properties of both liquids (viscous solutions) and solids (elastic materials), making it suitable for audio components like analogue turntables, CD players, amplifiers and loudspeakers.


1. Combines shock absorption, good memory, vibration isolation and vibration damping characteristics.

2. Proves very effective as an acoustic damper and absorber, combining all these characteristics in a stable material with a long fatigue life.

3. A lower creep rate than other polymers (rubber, neoprene, silicone, etc.).

4. Has a superior damping coefficient, over a wider temperature range than any other polymer.

5. Unlike fluid-based shock absorbers or foam products, Sorbothane absorbs shock efficiently for millions of cycles.

6. Eliminates the need for metal springs to return the system to its equilibrium position after absorbing a shock.

bFly-audio Line-up:

Currently seven series of shock absorbers featuring bFly-audio's Multi-Layer Adjustment Technology are available with a brass isolation layer as standard.
