The Pro-Ject EVO 10 AS Premium HG is a 10-inch S-shaped tonearm with a gimbal pivot on Swiss ABEC 7 bearings, a stainless-steel bearing block and silver wiring, in the HG version with hand-polished aluminium parts. It fits turntables with 238 mm between arm pivot and platter centre.
EVO 10 AS Premium HG: the technical details
Within the series the EVO 10 AS Premium HG takes the middle position. Effective length is 254 mm and the mounting point has to be marked 238 mm from the platter centre; the offset angle comes to 21.4° and the overhang to 16 mm. Effective mass is 25 g with the headshell and 11.7 g without. The counterweight covers cartridges from 6.5 to 18 g, and tracking force is set anywhere between 0 and 3 g. The HG suffix marks the version whose visible aluminium parts are polished by hand.
What sets the Premium arms apart is concentrated around the pivot. The inverted gimbal uses selected Swiss ABEC 7 bearings with four stainless-steel points; they sit in a heavy block of stainless steel, and the inner ring is a new design, solid and massive. The outer ring stays open to keep bell-like resonances away. All of these parts are CNC-machined to tight tolerances, and the scales confirm it: without its flange the arm weighs 507 g.
The S-shaped aluminium tube, chosen for its high internal damping, carries an SME-fit headshell at its tip that comes off quickly when you want to change cartridge; headshells in different materials are in the catalogue too. Pro-Ject credits the S form with lower distortion from groove-angle error and more secure tracking. For azimuth, slacken the one screw holding the tube and turn it. VTA is corrected by raising or lowering the arm steplessly after releasing two grub screws, and the silicone-damped lift follows the new height.
The internal wiring is high-purity silver, with selected and matched crystal conductors, and the leads running from headshell to cartridge are the same material, each ending in a gold-plated clip. The TPE-damped counterweight is a new design as well. The signal leaves through a gold-plated five-pin DIN socket.
