Enterprise Tonearm Mk4

Hearing an Enterprise is an unforgettable event. Breathtakingly realistic, it simply lets the music flow out to the listener in an unmediated way. Although it deserves the very best turntables and cartridges that money can buy, it unlocks huge performance gains from lesser ones and makes mediocre recordings positively sing. From its massively powerful and highly tuneful bass to a treble that is gorgeously silky yet amazingly spacious, it’s a sublime performer. The mineral clarity of the mid band is uncanny, and the sound staging profound. Prospective purchasers of a high-end tonearm owe it to themselves to audition this seminal design.

Features:

Higher Strength Low Resonance Arm-tube - The high-grade aircraft alloy tube is stiffened with carbon fiber. In addition, the tube is processed for improved resonance control. A long rear stub sleeve provides further reinforcement, and this is carefully interfaced to provide maximum energy dissipation and minimal reflections. This frees up your cartridge to perform as it should – away from the coloration and disruption caused by resonance and reflected vibration.

Sleeved Rear Stub - with a larger diameter, higher strength and improved energy dissipation. This improves counterweight stability in vibration – thus enabling the arm tube to hold the cartridge more steadily.

Rigidly Attached Counterweight - The counterweight attachment has been carefully engineered to hold the armtube more rigidly for cartridge stability whilst at the same time decoupling itself to minimize energy reflection back down the tube. The results are clearly heard in improved dynamics and a sense of power and control in the bass.

Low Resonance Counterweight - Counterweight resonance is reduced using a higher-grade material and then applying a dampening coating.

Counterweight Fine Adjuster - allows you to easily set the tracking force with a high degree of accuracy.

Headshell - features improved de-coupling and lightweight finger-lift. Sophisticated Yoke Decoupling - with several additional isolation interfaces from the vertical bearings

Dual Pivot Bearings - For vertical arm movement, the bearings consist of Ultra-hard tungsten carbide points sitting in hardened and burnished steel cups. This combination not only delivers incredibly low friction levels but is also much more robust than jeweled bearings which tend to shatter under stress. The results are incredible transparency, fluidity and retrieval of fine detail.

Ceramic Bearings - For horizontal arm movement, the ball bearings are upgraded to highly specified ultra-low friction Ceramic bearings.

Precise & Accessible VTA Adjuster - VTA can be adjusted precisely and infinitely using a large diameter calibrated dial. A further advantage is that all adjustments can be carried out above the arm-board (unlike lower arms in the range which demand access below the arm-board).

Azimuth Adjustment

Falling Weight Side Bias - Tests show this to be the highest performing method of achieving side bias. It has lower friction, better constant force and lower resonance than other alternatives such as magnets, springs, levers and twisted threads.

Internal Wiring - is ultra-low loss Silver Hybrid version producing greater transparency, detail and freedom from artefacts.

Silver-plated Headshell Clips - At such low signal levels electrical interfaces can be heard and silver marginally outperforms gold.
