AG Lifter: The Live Frame Revolution

Your audio system is only as good as the foundation it rests upon. Every component—amplifier, preamplifier, turntable—generates its own resonance, from low frequencies to ultra-high frequencies. Conventional racks store this energy, releasing it later as smear, timing errors, and lost definition. The result is a sound that is sluggish, constrained, and ultimately, untrue to the recording . The AG Lifter Crescendo Modular Rack, proudly engineered and manufactured in New Zealand, solves this problem at its source .

The AG Lifter Philosophy:

Don't store energy. Release it in real time.

For over 35 years, AG Lifter founder Andre Gil has applied his extensive background in industrial engineering and automation to the challenge of resonance management. Their motorsport engineering pedigree informs every aspect of the Crescendo design . The result is the Live Frame approach—a tuned exoskeleton that channels resonance through the rack and disperses it immediately through the finned pillars. Nothing is stored. Nothing is delayed .

A Masterpiece of Engineering.

Consider the Crescendo 4-shelf rack: it comprises 287 individual components and over 11.4 metres of alloy . Every detail is purposeful, from the custom-designed aluminium extrusion (ISO 9001 certified and patent-protected) to the proprietary fastener that tensions the frame for optimal performance .

Multi-Layer Isolation Technology. The Crescendo system employs three distinct layers of isolation working in harmony :

Ground Level: Four Dulcet 20 (Large) Isolation Feet decouple the entire rack from floor-borne vibrations.
Module Level: Stainless steel bearings, seated in billet CNC-machined caps pressed into vertical extrusions, decouple each shelf module.
Component Level: The 20mm ultra-rigid acrylic shelf rests on adjustable Dulcet 19 (Small) Isolation Feet, which can be positioned for perfect component placement .

The acrylic shelf material was chosen after extensive research for its superior vibration absorption properties, preserving low-frequency weight and soundstage scale without adding undesirable colouration .

Live Frame Technology.

The Crescendo frame is not a dead, mass-loaded structure. AG Lifter rejected the conventional high-mass approach in favour of a lighter, "tuning fork" design that actively manages resonance . The proprietary aluminium extrusion profile was designed with maximum surface area to release energy quickly into the air. The result is a frame that is damped enough to eliminate noise yet remains "live" enough to deliver an exciting, dynamic sound .

Tailored to Your System. The Crescendo's modular design means you can start with a single module and build as your system grows. Choose from 2, 3, or 4-shelf configurations, or add a dedicated Crescendo Power Amp Stand . The Dulcet feet are available in two bearing options—REF 70 Rubber (recommended for power amplifiers, integrated amps, streamers, and turntables) or 316 Stainless Steel (recommended for DACs and other digital components)—allowing you to fine-tune the sonic character to match your equipment .

The Sonic Result. Adding an AG Lifter Crescendo Rack transforms your listening experience:

A lower noise floor and quieter background
Expanded soundstage height, width, and depth
Deeper, tighter bass with increased definition
More organic, natural textures across all frequencies
Imaging that "snaps" into focus
