How to choose an upgraded tonearm.

Whatever you buy, make sure that it's adjustable. That is: VTA, VTF, azimuth, anti-skating (if applicable).

If you're prepared to accept a little quirkiness, you can take advantage of the greatest bargain in high end: the Trans-Fi Terminator, an air bearing linear tracker. Actually, that's air horizontally and a mechanical pivot vertically. Direct from the manufacturer, on the net.

Performs on the level of anything costing less than a new car. I use two: one with a Nottingham Analog upgraded to near Dais specification running a Miyajima Zero, and a DIY air bearing unit running a higher end Koetsu. Bonus: they are perfect for modifying and tweaking, which you need to do if running low compliance MC cartridges like these.

Reminds me of my old Bang and Olufsen Beogram 4002 tangental straight arm tracking tonearm. Probably not nearly sophisticated as yours.

The description is from Vinyl Engine offering an explanation on the DTS System utilised by Audio Technica.

I believe it is this Tonearm that was the birthplace for the commonly used philosophy for a design, that has a Stylus Contact Point and Pivot Vertical Motion Point designed to be at the same level. (Pivot in the Plane of the LP, is a loose description for this design)   

To get the Math on the principle might be a little more difficult to acquire.

AT - 1010 is a DTS (Dynamic Tracing System) Tonearm that blends an original design with new materials.

Also, the tracing performance of Universal Tonearms has been Totally Reconsidered in this new design.

Development efforts were aimed at improving the overall tracing performance of the dynamic system with a cartridge mounted.

This results in Improvement in Auditory Sensitivity and Elimination of Resonance.

One of the most obvious features of the AT-1010 is to Stabilise Stylus Force in Dynamic Variations, an inherent problem with Conventional, General Arms, caused by the change in velocity of the modulated record groove.

For this purpose, the front pipe is set at a far higher location than the pivot bearing.

Also, the arm is equipped with a damping mechanism to damp low frequency resonance.

As a result, this Tonearm gives a tracing performance that is in no way inferior to an integrated arm.

Review

The AT1010 exhibits a refined geometry, whereby the vertical motion pivot axis is in line with the stylus tip, thereby minimising the effect of varying stylus drag upon instantaneous downforce.

Forget my suggestion. I understand that it's now being made in Russia, not England.

Terry, will do. Nothing Russian now for sure,

Pindac, appreciate you explanation.
