Ortofon Launches The Windfeld Ti Cartridge

- Michael Fremer

Between 1976 and 2006, Per Windfeld oversaw the development of cartridges from the top to the bottom of Ortofon’s extensive line, including the MC 20, MC Rohmann, and MC Jubilee, as well as Ortofon’s many series of models: MC Super, Kontrapunkt, MC Rondo, and the budget-priced OM and Concorde DJ series. In a recent interview, Windfeld said that he figures he’s developed at least 50 cartridge models. I’m glad he’s still going strong, and has lived to see the remarkable resurgence of vinyl.

The original Windfeld cartridge was the first developed by its namesake’s successor, Leif Johannsen, Ortofon’s manager of R&D. It retained many of the Per Windfeld innovations found in other Ortofons, including Wide Range Damping (WRD): two dampers of different viscosities clamping between them a small, heavy, metal disc. At the time, Ortofon claimed that the WRD assembly produces ideal motor damping throughout and beyond the audioband, to help produce a linear, unusually extended frequency response and outstanding tracking at a vertical tracking force (VTF) of 2.6gm.

The original Windfeld’s low-mass, high-rigidity generator had a boron cantilever and coils wound with Ortofon’s Aucurum wire—gold-plated, 99.9999%-oxygen-free monocrystalline copper—onto a precision armature. The claimed results are high channel separation, lower distortion, and better channel balance. A strong neodymium magnet system combined elements of Per Windfeld’s Kontrapunkt and MC Jubilee designs with a Field Stabilizing Element (FSE) inside the magnet system, to produce a linear magnetic field throughout the armature’s movement. The result, according to Ortofon, was a 4 ohm, 0.3mV-output system with lower levels of intermodulation and dynamic distortion.
