Gold Note B-7 ceramic
Overview
The B-7 Ceramic is a tonearm handcrafted in Tuscany by Gold Note. Designed in a 9-inch format, it combines three materials—titanium, ceramic, and aluminum—and can accommodate most phono cartridges on the market, up to a weight of 15 grams. Its ceramic bearing system, developed by the German manufacturer GRW, is the central element of its mechanism and ensures smooth movement with minimal friction.
A hybrid construction where each material plays its part
The arm tube, fully machined from titanium, features a rarity: it is divided into six sections of varying diameters, an approach that effectively manages resonances while maintaining optimal rigidity. This structure starts with a diameter of 12 mm, with a wall thickness of 0.6 mm, and gradually evolves over its full length of 242 mm.
Black anodized aluminum makes up the pivot and the headshell. This choice provides a light yet stable structure, with a total weight of 195 grams without the counterweight. The black anodized finish visually contrasts with the natural titanium of the tube, creating a signature look that stands out instantly.
The main counterweight, machined from stainless steel, offers sufficient density to properly balance the arm with most cartridges. Additional counterweights are available for particularly heavy cartridges, ensuring total system adaptability.
GRW bearings: where German precision meets Italian design
At the heart of the B-7 Ceramic are four ceramic micro ball bearings, an exclusive design developed by GRW specifically for Gold Note. This German company, based near Würzburg, has been manufacturing precision bearings for over 50 years and specializes in high-performance miniature bearings for demanding applications such as aerospace and medical instrumentation.
The ceramic balls use silicon nitride (Si3N4), a material 60% lighter than steel with exceptional hardness. This combination offers several tangible benefits: five times the wear resistance of traditional steel bearings, total corrosion resistance, and above all, minimized friction. Each bearing is individually tested, then hermetically sealed in a controlled environment to preserve its mechanical characteristics.
The bearing layout follows a precise architecture: two micro-bearings manage horizontal movement, directly integrated into the precision-ground main pivot. Vertical movements are controlled by ultra-low-friction ceramic ball bearings, pivoted via manually adjustable stainless steel bolts. This configuration delivers completely silent tracking, without the parasitic noises often associated with traditional pivots.
Geometry and technical parameters: precision to the millimeter
The effective length of 242 mm with a 19 mm overhang places the B-7 Ceramic in the standard 9-inch arm category, making it easy to install on most high-quality turntables. The 24-degree offset angle has been calculated to minimize tracking error across the entire record surface.
The dynamic effective mass of 10 grams is a judicious compromise. This value allows the arm to work properly with a wide range of cartridges, from medium-compliance models to low-compliance MC cartridges. The nominal tracking force (VTF) of 0.176 Newton (18 grams) matches the needs of most modern cartridges.
The 23 mm diameter mounting shaft ensures compatibility with the vast majority of turntables on the market. This standardization makes the B-7 Ceramic a direct upgrade for many existing setups.
Adjustment systems: between ease of use and surgical precision
VTA (vertical tracking angle) adjustment is handled via an adjustable collar located at the base of the arm. While it doesn’t allow on-the-fly adjustment, it provides perfect stability once set. The system holds the chosen position firmly with no risk of drift over time.
Azimuth is adjusted directly at the headshell via two 2 mm hex micro-screws. This approach enables fine adjustment of the stylus’s perpendicularity to the groove, a crucial parameter for channel balance and minimizing distortion.
The anti-skating system uses the proven thread-and-weight method, inherited from the legendary SME arms of the 1950s. Five predefined positions allow you to tailor the anti-skating force to the tracking force used. This purely mechanical solution avoids introducing springs or magnets that could influence the arm’s dynamic behavior.
The hydraulic cueing lever ensures a controlled and repeatable descent of the arm onto the record, protecting both the stylus and grooves during handling.
Internal wiring and connectivity: uncompromised signal transmission
The internal wiring uses shielded AWG36 Hyper Litz oxygen-free copper (OFC) with 99.9999% purity. This Litz construction, where each strand is individually insulated, minimizes skin effect at audio frequencies and reduces cable capacitance. The shielding effectively protects against electromagnetic interference without adding significant mass to the system.
A custom 1.5-meter external cable is supplied, featuring a 4-pin DIN connector on the arm side and RCA plugs on the preamplifier side. The build quality of this cable meets the standards set for the internal wiring, ensuring consistent signal transmission from the cartridge to the electronics.

Frequently Asked Questions
Is the B-7 Ceramic compatible with my current turntable?
With its 23 mm mounting shaft and standard effective length of 242 mm, the B-7 Ceramic fits the vast majority of turntables that accept 9-inch arms. The pivot-to-spindle distance must allow for a 19 mm overhang. Check these dimensions in your turntable’s manual or contact the manufacturer if in doubt.
What’s the difference between ceramic bearings and traditional steel bearings?
Ceramic bearings offer 30–50% lower friction, up to five times longer service life, and above all, completely silent operation. Their corrosion resistance eliminates the risk of seizing after long periods of inactivity. The lighter ceramic balls also reduce system inertia, improving the arm’s responsiveness to groove modulations.
Why six sections of different diameters on the titanium tube?
This design allows precise control of the tube’s resonance modes. Each change in diameter alters the local resonance frequency, preventing the establishment of standing waves along the arm’s full length. The result: a more neutral transmission of the cartridge’s mechanical signal, without coloration added by the arm itself.
How do I correctly set thread-type anti-skating?
Start by positioning the thread at the setting corresponding to your tracking force. For example, for a force of 2 grams, use position 2. Then fine-tune by listening to the final tracks of a record: if you hear distortion mainly in the right channel, slightly increase anti-skating. If it appears in the left channel, reduce it. Perfect balance yields a centered, stable stereo image.
Does the arm require special maintenance?
The sealed ceramic bearings require no lubrication. Simply check every six months that the mounting screws are tight and the wiring is in good condition. Regular dusting with a soft brush is sufficient for routine care. Avoid harsh cleaners on anodized surfaces.
Can I use any cartridge with this arm?
The B-7 Ceramic accepts all standard half-inch cartridges up to 15 grams, covering 99% of the current market. Its effective mass of 10 grams is particularly suitable for cartridges with compliance between 10 and 25 μm/mN. For very heavy or very low-compliance cartridges, additional counterweights may be required.
