Preface<\/h3>\n

Following my previous AG Lifter review of the Crescendo Power Amp Stands<\/a>, this second review will focus on the AG Lifter range-topping Apollo Modular Audio Rack as a whole, and the Apollo H-Frame turned into an Apollo Power Amplifier Stand.<\/p>\n

About AG Lifter<\/h3>\n

As a part of AE Gil Technologies, AG Lifter is a 100% New Zealand-owned and operated engineering-based company, born of over 35 years of experience in industrial engineering, design, and automation, with engineering capabilities extending into category one motorsport. Andre and Vanessa Gil, Company Directors, Audio Resonance Management Designers, and passionate music lovers, created AG Lifter out of a devotion to high-quality audio reproduction. They listen a lot to live music and judge their own product on its musicality with a lot of emphasis on the sound stage and the naturality of tone. The underpinning design philosophy was to build a rack for music lovers.<\/p>\n

The original AG Lifter Mk 1 Isolation Foot was the catalyst for understanding the problems present in the Audiophile\u2019s listening environment. At present day, the product is in its Mk 6 incarnation and this Footer alone went through over 40 changes from its conception. Out of knowledge gained from the development of this footer, the racks came into existence and in total, there are now seven AG Lifter Audio Rack models in different finishes.<\/p>\n

AG Lifter audio isolation products are designed to be a mechanical diode that manages resonance from entering audio components, both externally but also internally. According to AG Lifter, it is a general misconception that harmful vibrations only enter audio equipment externally from the room.\u00a0 As the company points out, most harmonics are actually generated internally by the audio equipment itself.<\/p>\n

AG Lifter Range<\/h3>\n

The AG Lifter audio rack range was designed to fit in with most contemporary and classic interiors. The Apollo Modular Rack is part of the premium range, followed by the Crescendo Modular Rack range. Both incorporate technologies that deliver their enhanced performance through the use of layers of isolation and coupling\/decoupling. In addition, the Apollo Rack has an updated frame, which further optimizes the tunability of the rack. Furthermore, the High-Performance Coating (H.P.C), has been incorporated for the Apollo range of brass isolation components and coupling\/decoupling.<\/p>\n

\"\"<\/p>\n

The Apollo Isolation System encompasses several layers of Isolation starting from the ground using the Brass HPC (high performance coating) Dulcet 20 (Large) Isolation Feet. Each module is then decoupled utilizing Stainless Steel bearings housed in a billet brass H.P.C. machined cap which is pressed into the vertical extrusion. Each 20-mm thick acrylic shelf is then isolated using the Brass HPC Dulcet 19 (Small) Isolation Feet. The Dulcet 19 H.P.C. Brass Isolation Feet are adjustable in depth by simply unscrewing and re-tightening them by hand. They are also adjustable in width by loosening the Aluminum beams using an Allen key after which they can be freely positioned for fine-tuning. The Brass HPC componentry delivers greater clarity and a lower noise floor. The frame is a custom-designed aluminum extrusion (ISO 9001) with Brass HPC billet caps (instead of aluminum as used for the Crescendo system), that dampen the extrusion. The custom extrusion is designed by AG Lifter and carries a patent covered by the New Zealand Aluminium Supplier.<\/p>\n

The pillar profile was designed to have the maximum amount of surface area to quickly release energy.\u00a0This extrusion is born from extensive research and development testing many different profiles, and a proprietary fastener used to apply tension to the extrusion. The aim was to achieve a dampened frame that is nevertheless “live” enough to provide exciting sound. Frame finishes are available in Black and Silver, including complimentary capping finishes.<\/p>\n

The Apollo 4 shelf rack has no less than 352 components and 15.6 meters of extrusion!<\/p>\n

\"\"<\/p>\n

Top: Apollo; bottom: Crescendo<\/em><\/p>\n

The Apollo range encompasses a Power Amp Stand as well as a full rack solution. Its modular nature means that a user can start with a single-module 1-shelf or 1-H-Frame solution and build out the system as needed.<\/p>\n

\"\"<\/p>\n

The Apollo Rack’s modular design allows the user to set up each module at a time and wire up the equipment as you stack it. Certainly with very heavy components, it is easier to lift them in from above, rather than sliding them in from the front. Each level is coupled to the one below it via Stainless Steel bearings that interface with Brass cavities in the top and bottom vertical pillars.<\/em><\/p>\n

\"\"<\/p>\n

When assembled, the rack is surprisingly sturdy and the ball bearings really grip well, making the construction feel as if it is one single piece.<\/em><\/p>\n

\"\"<\/p>\n

The rack can be ordered in a 2, 3, and 4-shelf version with a standard 240 mm of vertical equipment space. As standard, the outer dimensions of the frame are 600 mm x 600 mm. With 500 mm between the pillars, both in width and depth\u00a0and basically unlimited free space in the rear so long as the component’s feet are supported on the 600 mm deep Acrylic platform, all audio equipment should fit comfortably. Additionally, the user can freely specify the desired pillar height to match the audio components used.<\/p>\n

\"\"<\/p>\n

Isolation Technology<\/h3>\n

The AG Lifter design drains the harmonics from the audio equipment, dampens, then transfers into the live frame dispersing the resonance in \u201creal-time\u201d through the AG Lifter proprietary alloy extrusion and pillar profile. The AG Lifter Racks are built to order and set up per the customer’s equipment, and the Acrylic platform supporting ball bearings are swapped out as needed for the designated audio component.<\/p>\n

There are 2 types of bearings to support the Acrylic platform: REF 70 Rubber and 316 Stainless Steel.<\/p>\n

Rubber REF 70 bearings are recommended to be used for the following equipment:<\/p>\n
