Once audio aficionados and budding audiophiles have settled on a turntable, they have the daunting task of choosing the phono cartridge. If you want to go up a notch, try the Clearaudio Statement turntable with real-time speed control for $125,000 (Fig. Janine Elliot takes a listen to the Soundsmith Carmen Moving Iron Cartridge that is made in the US and costs £759.00. Soundsmith Moving-Iron Cartridges Offer Best of Both Worlds Enjoy the best of both worlds: Soundsmith's moving-iron cartridges encompass the advantages of moving-coil and moving-magnet designs while simultaneously lessening or eliminating the respective approaches' deficiencies. The Sussurro moving-iron cartridge from Soundsmith also resides in a wooden body, employs a nude contact line diamond stylus, and weighs 8.79 g. That rounds up a fairly direct and not too technical comparison of moving-magnet, moving-coil, and moving-iron phono cartridges. They are connected to the tonearm via 2 vertical screws and 4 wires.P-mount cartridge is hooked up to the tonearm directly via 4 pins (T4P plug) on its back without any additional adjustments.Some users are not sure of their ability to determine the type of cart correctly. Even though extremely few brick-and-mortar outlets sell vinyl recordings, or even CDs, there is still a significant demand for vinyl and the three different kinds of cartridges—moving magnet, moving iron, and moving coil—that turntables need for playback. Post by tarkin0987 » 01 Sep 2009 00:20 I have come across a working AKG P7E cart with badly worn stylus. Soundsmith cartridges overturn the myth that moving coil cartridges are the only path towards perfection. Moving Iron Cartridges. The stereo moving-magnet cartridge design places a tiny permanent magnet on the end of the stylus cantilever, where it is suspended between two coils. 4). 1). Aside from their differing design concepts, MMCs, MCCs, and MICs each have their pros and cons. 1 watchers. The market is calling for smaller connection profiles, industrialized connectors, and a consistent interface (think RJ45) to take over the industrial Ethernet environment. According to its inventor, the moving micro cross eliminates many magnet and coil mass concerns and exhibits far better channel separation because left and right channel motion occurs on separate axes. The cartridge, which houses a variety of components (coils, cantilever, precious metals and stones, magnets, etc. 9. Both ranges feature a hierarchy of user-replaceable diamond stylus profiles to complement your chosen performance level. If one views them objectively, then it should be fairly easy to make a subjective purchase—maybe. Buy It Now. The output generated by moving coil cartridges range from as low as .13 mV to as high as 2.5 mV. 5. " Good price, high output and a winning musicality make this moving iron cartridge the one to beat." Soundsmith SMMC1 moving-iron phono cartridge Page 3 You won't mistake the SMMC1's retrieval of detail, or its less-than-first-class reproduction of microdynamic gradations, for those of a premium-priced modern MC—nor did it reveal the most delicate inner musical textures, as those top-shelf transducers do. A moving iron or induced magnet cartridge has no magnet attached but the cantilever is in close proximitry to a fixed magnet. The tiny magnets (positioned between the two coils) vibrate, and in … Sign up for Electronic Design eNewsletters. 7. Roy Gregory, Hi-Fi+, 7/01, P98-99 In a stereo moving-magnet cartridge (MMC), a miniscule permanent magnet rests on the end of the stylus cantilever suspended between two coils—one for the left and one for the right audio channels (Fig. 8). But with cost and complexity come fruits. Initial search for information found several favourable reviews. 6). Channel balance verified with Fozgometer and Analog Productions Ultimate LP Test Disc. My own collection of Cartridges has morphed from Ceramic to Magnetic, to MM, MI and MC. For the highest accuracy and most detailed listening experience we offer a selection of excellent moving coil cartridge designs. Its relatively high compliance makes it compatible with low to medium-mass tonearms. The magnetic field induced in it by the large fixed permanent magnet suspended above it induces a changing magnetic “flow” through the pole shoes which, in turn, generates an electromotive force in the fixed coils in proportion to the mechanical vibration. A moving magnet (MM) cartridge achieves the energy conversion by connecting the vibrating cantilever to a set of magnets that then vibrate in close proximity to a pair of coiled wires. The coil must be connected to a special phono amplifier input via the turntable leads so that the low voltage generated by the cartridge (typically 5 mV) is boosted to several volts to drive the speakers. Phono Cartridges From the grassroots beginnings of being hand-built on a kitchen table in 1953 to still being hand-built by the Grado family in Brooklyn today, these are what started it all. The component’s cantilever measures 6 mm long and 0.3 mm in diameter. It enlists three Teflon tubes to damp wire vibration and a digital processor that provides Recording Industry Association of America (RIAA) correction. In high-fidelity systems, crystal and ceramic pickups have been replaced by the magnetic cartridge, using either a moving magnet or a moving coil. 6. This type of generator is similar in operation to the moving-magnet type except that a very light, hollow, temporary magnet or armature … 2 grams, on average, where most MM's top out in the 1.5gram range. With an output of around 100 µV to 300 µV, MCCs are very susceptible to noise and hum. The Ortofon OM and 2M, Grado, B&O, ADC XLM Mk 3 and others are induced magnet cartridges. This market is truly passion-driven by knowledgeable and opinionated audiophiles, the curious novitiates who are venturing into the dark worlds of analog audio for the first time, and those who are both maintaining and expanding their investment in vinyl recordings. A somewhat proprietary design patented by Bang & Olufsen and not a general consideration, the moving micro-cross cartridge is a spinoff of the moving-magnet/iron topology. Getting them to agree on which moving coil is best is another story, which is a good thing in the grand scheme of market health. Opinion on AKG P7E moving iron cartridge. Single Pair Ethernet connectors will be used any time a small connection profile is needed, as well as when a customer wants to easily integrate devices and simplify circuit layouts. Any one of the three cartridge types does a fine job if it’s well designed and constructed, which is usually the case even in lower priced, entry-level components. For example, the Continuum Caliburn relies on a magnetically levitated magnesium platter suspended in a vacuum to thwart vibrations (Fig. Lyra Delos Moving Coil Cartridge.
