Many manufacturers of high-end audio electronics, digital sources and turntables have repeatedly expressed that you have never truly heard a component’s sonic capabilities unless you hear it when it has been effectively isolated. Such are the effects of resonance within music systems that by simply adding isolation devices to your hi-fi system can instantly and completely transform the sound.

The Crescendo Amplifier Stand is the premium amplifier isolation device produced by AG Lifter and it incorporates technologies that deliver supreme performance through the use of layers of isolation and decoupling. The frame of the AG Lifter amplifier stand is constructed out of a custom designed proprietary aluminium alloy extrusion (ISO 9001) with polished and anodized custom billet caps which have been designed with dampening properties. This special extrusion resulted from extensive research and development which modelled and tested various profile designs. A proprietary fastener is used to further apply tension to the extrusion resulting in a frame which is perfectly balanced – dampened but live enough to provide an exciting sound.

The AG Lifter amplifier stand incorporates two levels of audio isolation (Dulcet 19 and Dulcet 20 Isolation Feet) and includes a frame designed to move the isolation points on each shelf individually from left to right and from front to rear. This provides greater tuning potential for the isolation of different amplifiers, which is achieved by tensioning the complete frame and which delivers sonic advantages as a result. A CNC machined 20mm heavy weight acrylic captive shelf supports the amplifier.

The frame is available in either an anodised silver or black satin durable finish and custom orders are welcome for any dimension of power amplifier or mono power amplifiers. Here are some of the features of this precision engineered stand:

  • Proprietary designed aluminium extrusion
  • Billet aluminium caps
  • Choices of Sliver or Black Satin finishes
  • Etched graduations to accurately calibrate frame adjustments
  • Dual Dulcet isolation feet technology
  • Upgradable to Dulcet HPC Brass Isolation technology
  • Adjustable isolation and frame design
  • Heavy Weight Captive CNC machined 20mm acrylic shelf
  • REF 70 bearing technology
  • Lower noise floor

The rare feature of being able to actually tune the stand to perfectly suit a specific amplifier means that you will never need to acquire another stand. The effects on the sound are profound – clarity, natural, life-like presentation. Unleash the potential of your power amplifier!


Why do isolation devices improve sound quality?

The presence of vibrations of various frequencies, also known as ‘resonance’ or ‘harmonics’, can be very harmful to the performance of audio components. In a music system, resonance can be ground-borne (be transmitted into the system up from the floor), air-borne (be transmitted into the system from the air surrounding the system) or originate from the actual audio equipment. Factors such as transformers, power supplies and electronic components resonate at various frequencies and these vibrations spread throughout the component internally and then out to the rack and through the rest of the system, mixing with vibrations caused by other pieces of equipment.

The performance of audio components are affected by these vibrations and in some cases they micro-phonically pick up these frequencies and repeat them, causing reverberations. The presence of resonances in a music system can result in a higher noise floor, ghosting effect, low level hum, a smearing, or lack of clarity of sound, blurriness or hard, glassy edge to your music.

Isolation devices mitigate these resonances, thus allowing the equipment to operate the way it was designed and to perform optimally.

What is the effect of introducing isolation devices to a system?

The addition of an AG Lifter Crescendo Rack can have the following effects on a system:

  • The sound becomes tonally correct and with increased weight, scale and authority.
  • Sound stage height, width and depth is expanded.
  • Quieter background, lower noise floor.
  • Imaging improves and the sonic presentation ‘snaps’ into focus.
  • A deeper, tighter bass performance with increased definition.
  • More ‘organic’, or natural textures.
  • An increase in detail across all frequencies.
