After 2 years of construction and prototyping, this fantastic tonearm is now ready for the market. Available in both 9-inch and 12-inch models.
All parts are CNC-turned and milled.
Engineering Excellence in Every Detail
After years of dedicated research and testing, I selected the finest ball bearings from Japan - chosen specifically for their ultra-low starting friction. This level of precision is essential, as a tonearm must perform countless micro-movements with absolute accuracy. The proprietary design also allows for the ball bearings to be easily replaced, ensuring long-term serviceability and reliability.
Audiophile-Grade Internal Wiring
Inside the tonearm, you'll find wires consiting of 35 ultra-thin copper strands—each just 0.032 mm in diameter - silk-insulated, wax-coated, and carefully twisted (braided). This exceptional wiring preserves the purity of the audio signal, providing a neutral and transparent path from cartridge to output. The result: breathtaking sound reproduction with zero coloration or distortion introduced by the tonearm.
Pure, Uninterrupted Signal Flow
As shown in the photos, the signal path runs directly from the cartridge to the RCA terminals - free from solder joints or mechanical contact points. This ultra-clean architecture minimizes signal loss and interference, significantly enhancing sonic performance.
Premium Components, No Compromises
The headshell clips are supplied by Audiosilente and crafted from phosphor bronze - renowned for its elasticity and conductivity - then finished with a gold plating. These are widely regarded as some of the best headshell clips available on the market today.
Full Adjustability for Optimal Setup
Every key parameter is fully adjustable, including VTA, azimuth, anti-skating, and overhang. The tonearm also features a precision micro-weight system at the rear, allowing you to set tracking force with an accuracy of up to 0.01 grams - ideal for fine-tuning and achieving the perfect balance for your cartridge.
Designed for Seamless Integration
The 9" version of the BJA tonearm is a direct drop-in replacement for Lenco L75 and L76 turntables.
It can also be adapted to fit the L70, L75s, and L76s models.
Compatibility with L78 and L78s is also possible, though please note that doing so requires forgoing the automatic shut-off function.
Sonic Harmony of Carbon and Aluminum
The combination of carbon fiber and aluminum delivers a sound that is both precise and spacious.
Both the headshell and arm pillar are grounded, ensuring optimal shielding and noise reduction.
Ideal Cartridge Compatibility
The BJA tonearm performs best with cartridges that have medium to high compliance.
That said, even low-compliance models can yield outstanding results - as demonstrated by the Denon DL-103R, which I use personally.
With most cartridges, the system achieves an ideal tonearm resonance between 7 and 12 Hz, ensuring stable performance and excellent tracking.
BJA Tonearm Tower for 12" Arms
The BJA tonearm tower was specially designed for 12" tonearms - including the popular BJA-12" model and other 12" arms. This allows you to add a 12" tonearm alongside your existing turntable without the need to purchase a new unit.
Custom Height & Stability
Each tower can be built to your desired height. The base is weighted with lead balls embedded in epoxy resin to ensure excellent stability. A 2mm thick rubber mat is attached underneath to prevent slipping.
Complete with Accessories
The tower comes equipped with a grounding wire and RCA terminals for easy setup.
Precision Positioning Tool Included
Every BJA tonearm tower includes a spindle-to-pivot distance guide, making it simple to position your tonearm accurately and consistently.
Upgrade your setup with the BJA tonearm tower - perfect for audiophiles who want flexibility without compromise.
