The K2 radial tonearm is a completely in-house development by LUPHONIC. The goal was to develop a high-quality tonearm with which the two turntables H1 and H2 can form a sonic symbiosis. The bearings of the gimbal have been realized via precise miniature ball bearings. The arm tube is made of low-resonance carbon and is partly responsible for the tonal strengths of this tonearm. So is the headshell, which after much experimentation is made of a sintered polyamide filled with tiny glass spheres. Thus, despite low weight, a high rigidity is achieved and at the same time the material prevents the propagation of sound-damaging resonances.
The K2 offers convenient and variable adjustment of tonearm height, tracking force, azimuth and anti-skating force. With the stainless steel counterweight, most cartridges available on the market with a weight between 5g and 14g can be balanced. The tonearm is also available separately and can be mounted on many turntables.
