Our team have worked tirelessly to improve every aspect of this new tonearm. Offering improved ergonomics, usability and sonic performance. Featuring a new bias assembly, re-designed stiffer vertical bearing housing, integrated arm clip and an improved spring housing with easier to read numbers. Other improvements include a Rega made, low capacitance phono cable terminated with high quality ‘Neutrik’ plugs, improved lower friction, precision horizontal and vertical bearings and a re-designed 100 g mild steel balance weight.

The legendary RB330

Designed using the latest 3D CAD & CAM technology, the new RB330 is the culmination of more than 35 years of tonearm design experience. Featuring a brand new bearing housing and our latest tonearm tube designed using intelligent redistribution of mass, ensure this arm will exhibit fewer points of possible resonance.

Extreme stability with almost friction free movement from the new high precision bearing assemblies guarantees to gather more information from your vinyl than ever before. Featuring a new bias assembly, re-designed stiffer vertical bearing housing, integrated arm clip and an improved spring housing with easier to read numbers. Rega made, new low capacitance phono cable with Neutrik plugs. Improved lower friction, precision horizontal and vertical bearings.

Rega is famed for its tonearm designs. One unique characteristic of these designs is the achievement of near frictionless movement horizontally and vertically whilst having no measurable free play in the bearing assemblies (and in reality one or two microns of pre load). Rega has spent over thirty years and invested heavily in this area of tonearm design where the removal of  microns of movement has such a notable effect on playback.

Look at a stereo vinyl LP under an electron microscope and you will see microscopic ridges and bumps that the diamond stylus of the pick-up cartridge tracks and reads. The length of a ridge depends on its frequency. The height is its amplitude.
Towards the centre of an LP, a 10Khz signal is just 26 microns long and if it’s very quiet it may be less than 10 microns high. If your tonearm has 10 microns of movement within the bearing assemblies (and even very expensive tonearms usually have much more play and movement), reading the bumps will be difficult and musical vibration will be lost in arm movement.

It is impossible to quantify exactly the musical distortion or loss of measured information. This is due to the random nature of pivot or bearing movement. However, it is easy to see that accurate measurement or tracking of a 10 micron bump is not possible if the tracking stylus can move randomly at least the same distance that it is trying to measure.
