The Ortofon Rondo Blue is a crisp cartridge that will please any level of listener. The Rondos body is composed of powdered wood suspended in a “resin matrix”, making the cartridge exceptionally bright and clear. The stylus on the Rondo Blue is a Nude FG 70 that offers flawless tracing on the record grooves.
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 Blue The Rondo Blue cartridge sound is defined to be more expressive and will distinguish higher from lower pitched instruments- yet well controlled by the influence of wooden material. The Nude FG 70 diamond is here mounted on a cylindrical aluminum cantilever again revealing a very flat frequency response passing 20 kHz including very high tracking ability at recommended tracking force of just 2, 3 gram. We find the sound picture will tend to suit customers liking orchestral music as well as smaller groups of instruments like chamber music smaller choirs and solo instruments. Recommended load- depending on volume or dynamic in music might be around 50 Ohm or even lower.
