Ortofon A90 Phono Cartridge In Stock
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 A90 The A90 not only celebrates the past 90 years of Ortofon, first and foremost it also makes history by significantly raising the standards by which sound reproduction is measured, making it a celebration of sound itself. This impeccably crafted cartridge carries with it the culmination of decades of research in the field of analogue sound reproduction along with the worldís best engineering, materials, and manufacturing techniques. Combined with the inspiration of the very best ears and minds in contemporary analogue technology, the A90 stands as a true contender for the best moving coil pickup of all time.
