Argo i The Argo i features Lyra's proprietary, Ogura-made boron rod cantilever/coil/original line-contact diamond stylus assembly. By eliminating pole pieces and using non-conductive materials, its extremely linear magnetic field is directly created by two symmetrical disc magnets. The body is machined from a single piece of hard-anodized aluminum alloy and hand assembly is entirely done by Yoshinori Mishima. The Argo i is an extremely refined cartridge capable of reproducing high levels of detail and sophistication in advanced analog systems. It requires a high quality phono amplifier with the capability of properly amplifying its 0.45mV output.
