Amber Ultra MC Cartridge
A NEW STAR IS BORN and ready for delivery April 10th, 2020!
Introducing the thrilling Allnic Amber Ultra moving coil cartridge, and its sibling the Allnic Purple.
These 2 cartridges are guaranteed not to displease. More pictures are coming soon, and we’ll be ready to supply the Amber on or about April 10th, 2020, with June delivery for the Purple. Feel free to discuss the observations in the “Description” section below, and pre-release sample pricing, with David at Hammertone at 250.826.6872.
Some trades considered.
The past 3 months of testing the new Allnic Amber Ultra and Allnic Purple has been a teaching and humbling experience.
Amber, the result of KS Park’s 20 year journey into the dark arts of producing successful moving coil cartridges, is the one that everyone will soon be referencing. For the past three months we have been experimenting with a variety of compliance, impedance, voltage output and resonance characteristics with the new bad boy of moving coils. This writer had no idea of the complexities and nuances that go into the exotic dollar per gram world of cartridge construction.
Having paired up with KS Park about what seems a million years ago (2008), I have owned about a dozen variations of his wood bodied Allnic Verito and Puritas catridges, the aluminum bodied Puritas, and now the soon be coveted, Allnic Amber and Purple. Early days, KS built Verito and Puritas with very low compliance necessitating the need for high mass tonearms. Some of the best arm / Allnic cart matching was with big club like arms such as Fuchs, Ikeda, FR66 and custom long wand arms emerging from Europe. Low mass arms like SME would not keep the stiff Allnic suspension in the grooves, resulting in unwanted high frequency energy and sibilant playback with less than stellar recordings. The low compliance was a mother of invention for the unusual separate magnet structure of KS’s designs. The ensuing years were a pursuit of a rubber suspension that would not dry out and be both supple enough to keep this blindingly fast cartridge in the groove and pliable enough to elevate the compliance enough for use with medium mass tonearms. Happily, after trials of custom rubber suspensions from the world’s rubber suppliers, a fellow Korean company was able to produce the perfect cartridge suspension rubber for Allnic. In addition, experiments with different materials treatments of the aluminum body have resulted in improved damping that enhances the relationships among all the elements of construction.
The specs enclosed are same for both carts. The sound of the Amber is deep, spacious, layered with organic weight, and life size with great energy. Dynamics and bass resolution are to envy for any manufacturer. The Fritz Gyger stylus and Boron cantilever combine to reduce record groove noise and provide excellent tracking.
The Purple has an Aluminum cantilever and a different cartridge body treatment, with the same sonic qualities as the Amber, with great pace and rhythm and maybe slightly less upper end energy. It works great with my hard attacking Altec VOTTs and offers lovely stage dimensions.
You will definitely want to hear the Olympic-level performances of these two new “track stars” from Allnic’s analog audio master, KS Park!
STRUCTURE MAKES A BIG DIFFERENCE
First, every LP record master is engraved using an LP cutting lathe’s cutter head. The Amber and Purple moving coil (MC) cartridges are designed to reproduce music via a mechanism that emulates the LP cutting lathe’s cutter head, of course, however, with a diamond stylus that tracks the record grooves’ faces, rather than with a diamond chisel for cutting the grooves into the vinyl.
Second, the Amber and Purple have two separate hollow polycarbonate bobbins, as opposed to one bobbin designed as an iron square or cross-block.
Third, iron is about nine times heavier than polycarbonate, so a conventional iron bobbin reacts with far less agility to the musical grooves of a vinyl record than one made of hollow polycarbonate.
Fourth, as a cantilever moves along the vinyl’s grooves, it needs a pivot. Conventional MC cartridges’ coils are located near the pivot because of their heavy moving mass. Because of its lighter moving mass, relative to conventional MC cartridges, the Allnic Amber and Purples’s coils are nearer to the diamond stylus. The result for the Amber and Purple is increased coil vibration capability and, therefore, more detailed audio reproduction.
The Amber and Purple also feature:
• A new rubber damper developed by Allnic
• New CCA (Copper Clad Aluminum) dual coils
• Fritz Gyger S stylus
• Amber: Solid boron cantilever (Purple: Aluminum)
• Zinc mounting plate
• Weight of 11 grams
Experience indicates that the Amber and Purple will continually improve over a minimum of forty (40) hours of playing time, reaching a level of performance well beyond their initial ones and, we believe, well beyond that of most MC phono cartridges.
