Lafayette F-2001
Little is documented about the Lafayette F-2001 electrostatic headphone system. What the record shows comes from period audio magazines, which place it as a noteworthy, if somewhat bulky, entry in the early-1970s electrostatic headphone market.
The F-2001 had fairly large but lightweight earpieces with comfortable seals. A separate energizer/control box drove them, housed in a walnut cabinet. The energizer ran either from an AC outlet or from internal batteries. AC was preferred for best performance, since the battery option reduced voltage without modification. It had two headphone jacks for simultaneous listening, individual level controls for each channel with roughly 20 dB of range, and a switch to reconnect the main speakers when the headphones were not in use. HiFI-Stereo (July 1972, p.70) gave the energizer dimensions as 3¼ × 6½ × 11 inches, a compact unit by the standards of the day.
The F-2001 was reviewed alongside models such as the Stanton Isophase MK III and Superex PEP-77C, which suggests it competed in the upper tier of headphone systems. Beyond those brief mentions, few specifics survive. No official frequency response, impedance, or sensitivity figures appear in the known sources.
