The Nexus headshell is engineered with precision from solid aluminum, undergoes rigorous machining to ensure compatibility with the arm tube. To maintain optimal vibration transfer, weight reduction holes are omitted, avoiding potential sound distortion and preserving image focus and sonic solidity. This results in a more accurate representation of vocals and instruments, with improved depth of field in the three-dimensional soundscape.

The secure placement of the cartridge above the record is crucial for avoiding distortions or loss of audio information. Rigid arm tubes are essential in ensuring stability, reducing unwanted movement and preventing the disappearance or smearing of vocals and instruments. The Nexus features a bespoke titanium arm tube, manufactured to stringent precision standards. The GR9 grade titanium boasts a 1.3mm wall thickness, providing unmatched strength and resisting bending or torsion modes that could negatively impact sound quality.

The structural rigidity of the tonearm is crucial for preserving the accuracy of audio reproduction. Tonearm bearings, like turntable bearings, are critical to performance and impact sound quality. All AVID tonearms undergo meticulous manual construction and individual testing to ensure optimal performance. High specification ball race bearings are meticulously fitted and both horizontal and vertical bearing shafts undergo machining and grinding to exacting limits, resulting in minimal friction and precise movement in desired directions, thereby preserving sound quality.

Inner groove distortion is a phenomenon that occurs when centripetal forces during platter rotation pull the tonearm towards the center of the record, leading to an imbalanced stylus pressure on the groove wall and resulting in distorted sound. To counteract this, tonearm designs require a bias adjustment mechanism, which increases the force gradually as the tonearm approaches the center, compensating for the varying centripetal force. 

Our tonearm design incorporates a mechanism that gradually increases force to counteract the centripetal effect as the tonearm approaches the center of the record, providing a unique solution to the issue of inner groove distortion. This results in consistent musical enjoyment from start to finish, differentiating us from other tonearm designs that may not address this problem as effectively.
