The Reed 5A and 5T are a tangential tonearm designs. Featuring unique design, innovative technological solutions and high quality and dedicated to a true audio passionate, it is one of the most advanced tonearms Reed have ever made.
Reed 5T technically is a tangentially tracking pivoted tonearm. It’s working principle is based on Thales’ theorem (if the center of a triangle’s circumcircle lies on the triangle then the triangle is right, and the center of its circumcircle lies on its hypotenuse) and the rule, that given three non-collinear points, it is possible to draw only one circle that has finite radius and passes through all three.
Arm tube suspension system is similar to one used in Reed 3P tonearm, and the tonearm’s turning part is based on low noise thrust-sleeve bearing. For angular rotation of tonearm Reed designed and built limited rotation sectional torque motor. Tonearm’s position is controlled by laser and linear sensor array.
Reed 5A features:
Armtube suspension system is similar to the one used in Reed 3P tonearm.
Tonearm’s back link uses low-noise ceramic rolling bearings.
Lever uses low-noise ceramic rolling bearing and rests on the sapphire – molybdenum carbide thrust bearing.
Sapphire – molybdenum carbide thrust bearings are also used for tonearm’s front link, vertical and horizontal axes.
Tonearm has VTA and azimuth setup and can be configured with Reed or SME (universal headshell connector) headshells.
To make sure tonearm setup is precisely horizontal, tonearm has integrated level and horizontal plane adjuster.
Comparing to regular pivot tonearms, Reed 5A does not require antiskating and has much less absolute tracking error (max. tracking error is +/- 4 Minute of Angle (MOA) (Fig.2). Pivot tonearms – approx. 1.2 – 2.5 deg. (Fig.3).
Comparing to other tangential tonearms, Reed 5A does not require any additional devices to work (e.g. compressors, electronic controllers), is compact and can be easily mounted on a wide range of turntables.
MANY, MANY combinations of finish (Black, Bronze, Gold, Palladium) wood armband choices (Teak, Ebony, Cocobolo), wiring (Copper, Silver, Cryo, 100cm, 125cm) and headshell (with or without Azimuth or laser option, finishes) options, etc., available. Please contact us before ordering.
