Reed 5T
Screenshot
Reed 5T is their first appearance in the tangential tonearm domain.
Featuring unique design, innovative technological solutions and high quality, and dedicated to a true audio passionate, it is one of the most advanced tonearms they have ever made.
Reed 5T technically is a tangentially tracking pivoted tonearm.
It’s working principle is based on Thales’ theorem (if the centre of a triangle’s circumcircle lies on the triangle then the triangle is right, and the centre 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. (Fig. 1)
- P1, O1, P3 – Thales’ semicircle,
- Angles P1-A1-P3, P1-A2-P3, P1-A3-P3 are 90 degrees each,
- Segments A1B1 = A2B2= A3B3 represent length of a tonearm,
- B – Tonearm vertical axis,
- P2 represents a center of circle, drawn through three points – B1,B2 and B3 (tonearm rotation axis),
- P3 – Linear Sensor Array,
- BP3 – Laser beam.
Arm tube suspension system is similar to the one used in Reed 2G tonearm, and the tonearm’s turning part is based on low noise thrust-sleeve bearing.
For angular rotation of tonearm they have designed and built limited rotation sectional torque motor.
Tonearm’s position is controlled by laser and linear sensor array.
Reed 5T has user-replaceable arm tube – feature, which allows to change tonearm’s effective mass yourself.
Tonearm also has VTA and azimuth adjustments.
Reed 5T has following advantages if compared with pivot tonearms:
Smaller moment of inertia,
No need for anti-skating mechanism,
Max tracking error is +/- 5 Minute of Angle (MOA). (Figure 2). Pivot tonearms usually have max tracking errors up to 1.5 deg.
Reed 5T’s advantages compared to other tangential tonearms:
Few times smaller moment of inertia,
No need for complicated additional devices (air compressor),
Compact and sleek design.
Effective mass in both vertical and horizontal directions is similar

The designer and company owner, Vidmantas Triukas, is radio engineer, working in hi-fi audio equipment field since 1985.
He was working in scientific acoustic and ultrasound area, researching the transmission of acoustic noise in different materials and has three patented inventions in this field.
In 1987, Vidmantas Triukas with a few friends built an “audio set”, consisting of turntable, speakers and an amplifier, and presented it in USSR’s largest technical achievement trade show in Moscow.
For various innovations ( turntable motor automatic speed control, amp with very low linear distortions etc.) it was awarded a bronze medal in audio equipment category.
After 1990s Vidmantas started business in another area, however audio still was his passion all these years.
In 2007 he decided to start business and offer something amazing to the market.
After a year of continuous research, prototyping, design and testing he offered first Reed series tonearm.
Since then, his company works for its valued customers and tries to bring something special to the audiophile community.
Despite that Vidmantas is an inventor and a technical designer, he is also very passionate art lover. He studied art history in Sankt Petersburg (formerly Leningrad) in 1980 – 1982.
