Ortofon Rondo Bronze Low Output MC Phono Cartridge
A Briefing on Ortofon Moving Coil Cartridges
Nothing demonstrates more convincingly Ortofon´s commitment to be the world´s last cartridge manufacturer than the ongoing development of new state-of-the-art models, and Ortofon will continue to refine upon the level of sound quality attainable from analogue recordings. Since 1948 Ortofon has introduced about 100 different moving coil models, and more are to follow. Contrary to other types of phono catridges, the moving coil principle is not suited for mass production. Each of the four coils contains between 11 an 24 turns of wire, depending on model, and has to be wound by hand under a microscope. The wire itself is much thinner than a human hair. The high degree of craftsmanship involved is one of the "secrets" behind Ortofon's reputation.
Details on the Ortofon Rondo Bronze
The sound from the Rondo Bronze cartridge is very detailed in its spectrum and differentiates the sound source in a refined and homogenous manner. Big orchestral music will be reproduced powerful yet well controlled and open up space around the instrument. The Nude FG80 diamond is mounted on a conical aluminum cantilever yielding very linear frequency response over the entire frequency range-at the same time ensuring very high tracking ability. Recommended load resistance between 500 and 100 Ohm depending on personal preference of openness. Higher load resistance will always tend to more liveliness and space in sound-image.
