Ortofon MC Cadenza Blue Moving Coil Cartridge

Why does the MC Cadenza Blue use a nude Line Contact diamond?

The MC Cadenza Blue is built around a nude Fritz Gyger 70 (FG70) diamond stylus, a Line Contact profile that also includes the Shibata and Ortofon Replicant 100 shapes in this category. A nude diamond attaches directly to the cantilever rather than being bonded to a metal shank first, so it carries less moving mass at the point of contact with the groove. Line Contact shapes are cut with a larger contact area against the groove wall than spherical or elliptical styli, letting the stylus track closer to the profile of the original cutting stylus used to make the record. On the Cadenza Blue, this diamond sits on a ruby cantilever, a stiffer material than the aluminium cantilevers used on lower-tier cartridges, which limits flex as the stylus moves through the groove. The coil itself uses 6NX (99.9999%) pure silver wire, and an improved winding process on the armature is built to hold channel balance within 1.2 dB at 1 kHz, keeping both channels tracking the groove signal at matched output.

Which tonearms match its compliance rating?

The Cadenza Blue is rated at 12 µm/mN dynamic lateral compliance, placing it in the moderate compliance range. Moderate compliance cartridges pair with moderate mass tonearms, meaning arms with an effective mass between 11 and 25 grams, such as the SME IV, SME V, SME VI, Triplanar, or Graham. Cartridge and tonearm form a resonant system together: their combined mass and the cartridge's compliance set a resonance frequency, calculated as F = 1000 ÷ (2π√(M×C)), where M is the total tonearm system mass and C is compliance. A resonance frequency between 7 and 12 Hz is optimal, with 10 Hz recommended. The Cadenza Blue weighs 10.7 grams, and this figure feeds directly into M alongside headshell and tonearm mass, so it's part of the calculation a buyer needs before confirming a match. A low mass arm rated at 10 grams or below is not a suitable pairing for this compliance rating, since it risks pushing the system's resonance frequency outside the workable range.

What phono stage requirements does it have?

The Cadenza Blue is engineered with 5 Ohm internal DC resistance and a recommended load impedance of 50 to 200 Ohm, figures that determine which phono stage inputs or step-up devices will load it correctly. Because it outputs 500 µV at 1 kHz, 5cm/sec, it needs a phono stage or head amp with sufficient moving coil gain to bring the signal up to line level before further amplification.

How should tracking force and angle be set during installation?

The Cadenza Blue is specified to run within a 2.2 to 2.7 gram tracking force range, with 2.5 grams recommended, and a tracking angle of 20 degrees. Setting tracking force within this window during installation directly affects how the FG70 stylus sits in the groove, and how well it can reach its rated tracking ability of 80 µm at 315 Hz.

Is the stylus replaceable over time?

The Cadenza Blue is a moving coil design, which means its coil and stylus assembly are fixed rather than user-replaceable. A cartridge with a replaceable stylus offers the advantage of straightforward upgrades later, and that advantage sits with moving magnet designs rather than moving coil ones. Choosing the Cadenza Blue means accepting that stylus wear or replacement is handled as a factory service, a trade-off buyers make in exchange for the nude diamond and silver coil construction detailed above.

Where does the MC Cadenza Blue sit against Ortofon's moving magnet range?

The MC Cadenza Blue is positioned within Ortofon's catalogue as a moving coil cartridge, set apart from the replaceable-stylus convenience of the moving magnet 2M series. Buyers who want the simplicity of swapping their own stylus, or who haven't yet settled on a phono stage with moving coil gain and matching load impedance, are better served by a moving magnet option. The Cadenza Blue instead suits owners who have a moderate mass tonearm already in place, between 11 and 25 grams, and a phono stage or step-up transformer that can handle a 5 Ohm source impedance and 500 µV output.
