Helius Designs was formed in 1982 following the demise of the Cambridge based company Tangent Acoustics, for whom I had developed turntables.

The bearing design is similar to the original Orion range dynamically balancing the bearings around a point of zero potential. The mounting geometry of the 10h arm is the same as the Omega, allowing direct interchangability. Counterweights are available in 3 sizes to accommodate various configurations of cartridge and length

In this configuration, 3 balls form a triangle in a close running journal with a 4th sphere pushing down into the centre of the triangle forming a tetrahedral array. This constitutes that absolute minimal friction levels possible in a captured bearing, yet also ensures point contact on all surfaces

Technically the arm is very sophisticated, being dynamically balanced, damped by differential masses and having non-coincident bearings. In addition, it pays close attention to small but significant details ranging from bracing ridges machined into the headshell, internal cue construction, silicon bias correction, collet clamping base plate, micro-adjustment of tracking downforce

Available in both 9" and 10" guises we also believe the design benefits from the use of single strand silver wire. Mounting geometry is identical to the Aurora and Omega arms making a straight upgrade delightfully easy. A feature borrowed from its more illustrious siblings is the incorporation of the cue device into the main pillar.
