Linn Krystal Moving Coil CartridgeThe Krystal is Linn's entry-level moving coil cartridge — the first step above the Adikt and Koil, and the cartridge that introduces the LP12 owner to what moving coil design, at Linn's level of execution, genuinely sounds like. At £1,535, it sits below the Linn Kendo and above the moving magnet and entry-level MC alternatives, occupying a position in the range that is deliberately considered: a cartridge whose capabilities are correctly matched to an LP12 at Majik specification, and which delivers the character of Linn's MC engineering without demanding more of the tonearm and sub-chassis than that specification can support.Moving coil cartridges operate on a fundamentally different principle to moving magnet designs. In a moving coil, extremely light coils are attached directly to the cantilever and move within a fixed magnetic field — the inverse of the moving magnet arrangement. The lower moving mass that results means faster, more precise stylus response: groove modulations are transmitted to the generator with less inertia in the way, and the signal that arrives at the phono stage is more accurate and more immediate than a moving magnet can achieve. The trade-off is lower output voltage — the Krystal outputs 0.5mV, which requires a phono stage with proper MC gain. This is not optional. An MM-only phono stage will not work correctly with the Krystal, and the phono stage question is the first conversation to have before specifying one.Vital Fine-Line Stylus — Precision Above EllipticalThe Krystal's stylus is a vital fine-line profile — a meaningful step above a standard elliptical in groove tracing ability and high-frequency resolution. A fine-line profile makes contact with the groove wall over a narrower, more precisely defined area than an elliptical, following the geometry of the original lathe stylus more closely and retrieving a greater proportion of the recorded signal with lower distortion. High-frequency content is traced more accurately; inner groove performance — where demands on the stylus are greatest — is more composed. The vital fine-line is not the most advanced profile in the Linn range — the Kendo's super-fine-line and the Ekstatik's micro-ridge go further — but it is a significant and audible step above the profiles used in moving magnet designs and entry-level MC alternatives.Aluminium Tube Cantilever — Rigidity and ControlThe Krystal uses an aluminium tube cantilever — lighter and more rigid than the plastic cantilevers found in budget moving coil designs, and a meaningful step in stiffness over moving magnet cantilevers. The cantilever's job is to transmit stylus motion to the generator with minimum delay and minimum energy storage — and aluminium tube performs that function with a consistency and precision that budget alternatives cannot match. The Kendo steps up to boron, which is stiffer still and with internal resonances further outside the audio band; the Krystal's aluminium cantilever is the correct specification for its position in the range, and the correct match for the Linn Krane Tonearm on an LP12 Majik build.Precision-Machined BodyThe Krystal body is machined from 7075-grade aluminium — the aerospace alloy used throughout the Linn cartridge range, chosen for its rigidity, dimensional stability, and consistent resonant behaviour. The same alloy appears in the Kendo, Kandid, and Ekstatik bodies above it in the range. At 7.0g, cartridge mass is correctly matched to standard LP12 tonearms at the Majik and Selekt level, and the triple-point mounting system ensures installation geometry is accurate and repeatable.Krystal and the LP12 Upgrade PathThe Krystal is the cartridge that correctly serves an LP12 at Majik level. The Linn Kendo is the step above — boron cantilever and super-fine-line stylus, designed for the Arko tonearm on a Kore or higher sub-chassis. The distinction matters: running a Kendo on a Majik LP12 means the cartridge cannot express its full capability, because the sub-chassis, bearing, and power supply beneath it are not at the level required to reveal what the Kendo retrieves. The Krystal is not a compromise at Majik level — it is the correct choice for that specification, and it is the cartridge from which the upgrade path to the Kendo is most logically taken when the rest of the system has been developed to support it.For those whose LP12 has been upgraded beyond Majik — running a Linn Karousel Bearing Kit and Kore sub-chassis, for example — the Kendo is likely the more appropriate choice. That is a conversation worth having before ordering.Technical Specifications Type Moving coil Output voltage 0.5 mV @ 5 cm/s Tracking force 1.5–2.0 g Channel separation Better than 30 dB at 1 kHz Channel balance ± 1 dB at 1 kHz Cantilever Aluminium tube Stylus profile Vital fine-line Body material Precision-machined 7075-grade aluminium Cartridge mass 7.0 g Load resistance 50–200 Ω Load capacitance 100–1000 pF Mounting points 3 Who Is It For?The Krystal is the right cartridge for an LP12 Majik owner who wants to move from moving magnet to moving coil — the natural step from an Adikt or Koil stylus replacement, and the entry point into MC performance at Linn's level of execution. It is also the correct choice for older LP12 builds at Majik specification where other components have not yet been upgraded, and for LP12 owners who want genuine MC character without the system requirements the Kendo demands.It is compatible with the Linn Uphorik phono stage as an external MC phono stage, and with the Urika for internal installations at Radikal-powered specification. The phono stage choice matters — the Krystal will reveal the quality of what it feeds into, and a phono stage that is not properly matched to its output and loading requirements will limit what it delivers.Buying from Martins Hi-FiMartins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind.Cartridge fitting, tracking force setting, and alignment are precision work — small errors in setup translate directly into reduced performance and unnecessary stylus and record wear. We carry out complete installation and alignment as part of our LP12 servicing work and will not return a deck until every parameter is correctly set. If you are considering the Krystal as part of a broader upgrade — alongside a phono stage change, for example — speak to us before ordering. The correct sequence and the correct supporting components matter, and the advice is part of what we are here to provide.When you get in touch, you'll be speaking with Dave, Chris and Tim — experienced specialists who can advise on this product and your whole system.Contact us at [email protected], call 01603 627010, or WhatsApp on 07554 687137.
