Stogi Reference 313

STOGI REF 313 is, as its name suggests, a 12.3” (313 mm) long version of the standard 9” STOGI REF tonearm. It shares many of the same materials and parts as the 9” tone-arm, but its increased 12.3” effective length results in significantly lower levels of tracing distortion and with carefully considered upgrades to key components,further improves musical performance.

The 12.3” arm-tube features exactly the same sleeve joint and precision worm drive for easy and repeatable azimuth adjustment, but also features a unique, ultra rigid removable head-shell, designed to make set up or cartridge swapping considerably easier. The hexagonal shaft on the one-piece machined cartridge carrier is a positive fit into the socket on the end of the arm-tube, locking securely in place with a captive grub screw. The bearing housing is identical to the standard STOGI REF, but the bearings themselves are ultra low friction, close tolerance, zero play, low noise and starting torque ceramic ball bearings that lower friction levels, further reduce bearing chatter and improve energy transfer. A larger diameter and carefully profiled counterweight keeps the balancing force and moment of inertia as close to the central pivot point as possible, also aiding tracking and the generator’s freedom of movement. The STOGI REF 313 retains the one-piece arm-wiring and termination options of the other STOGI series tonearms.

Combined with the reduced tracing-distortion of the increased effective length, these carefully executed upgrades deliver a substantial improvement in technical and overall musical performance.
