Clearaudio Reference Jubilee Turntable Available
Clearaudio's Reference Jubilee is a new take on the original Reference turntable released in the 1980s.
While Clearaudio's new Reference Jubilee retains the distinctive boomerang shape of its 80s predecessor, upgrades and updates can be found. Firstly, the 22kg Reference Jubilee sees its resonance-optimised chassis moving from acrylic to higher-performing and arguably more attractive, Panzerholz wood and aluminium.
Spotted last year, the new turntable's 6cm-thick platter is constructed from damped polyoxyethylene and rotates on a select version of the brand's frictionless Ceramic Magnetic Bearing, while below sits an 8.5kg stainless steel sub-platter.
Clearaudio's Optical Speed Control is built into this sub-platter and uses an optical sensor to monitor its rotational speed with 1,598 impulses per revolution. Once the control unit receives the readings, it offsets deviations by adjusting the motor's voltage via an operational amplifier resulting in a quoted measured speed accuracy of < ± 0.05 %.
To achieve a precise rotational speed, Clearaudio uses a 12-bit DAC to generate a motor reference voltage, which is converted into an analogue voltage signal. The digital reference is used only to compensate for slow movements or drifts due to factors such as temperature, oil viscosity and belt friction; meanwhile, the motor is driven purely by the analogue output stage.
Furthermore, the motor is a brand new design with a high-torque, air-core (non-magnetic) 24-volt DC motor and belt drive decoupled from the main chassis and suspended by a “network of elaborate rubber tightropes”.
The Clearaudio Reference Jubilee turntable is priced at $30,000 and is available now.

Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.
The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
