Rega RP8: An Evolutionary and Revolutionary New Turntable

We know what you're thinking: Rega's long-awaited RP8 looks like it belongs as the centerpiece in a modern art museum. Yes, it does. But this evolutionary and revolutionary design—anchored by a custom-made skeletal plinth—also sounds brilliant. Equipped with a new tonearm-bearing assembly, triple-layer glass platter, and 24-volt low-noise motor controlled by a hand-tuned electronic power supply, this 'table extracts the finest details from LPs due to its superior rigidity, low-vibration motor, double bracing, and ultra-stable RB808 tonearm. Unbelievable performance, incredibly low price: Rega pushes the boundaries like never before with the RP8. You need to hear it for yourself.

TTPSU power supply
The compact TT-PSU uses a high stability, crystal locked, low distortion sine wave generator. This, along with an efficient drive amplifier fed from a stabilised DC power supply, generates a 24V AC balanced signal of less than 0.05% distortion, which is completely un-affected by any changes in the mains/line voltage and conditions. This then drives the improved Rega anti-vibration circuit built into the RP8 motor PCB.

RB808 Tonearm
The RB808 tonearm is packed with new features pushing the boundaries of tonearm design. As with all Rega tonearms each one is meticulously hand built by a team of highly skilled technicians. The RB808 has improved bearings and a tightened spindle fit tolerance over previous models (each bearing is individually selected to find the perfect match for the chosen spindle). This is a proven method of increasing the amount of detail retrieved from the record surface.

A brand new low mass precision engineered vertical bearing assembly has been manufactured to further compliment the inherent design philosophy of the RP8 turntable. The RB808 uses the latest Rega arm tube. Completely redesigned to redistribute mass, further reduce stresses and resonances. This advanced design tube increases the stiffness and rigidity of the overall assembly using CAD design to blend the multiple varying tapers. Externally Rega have fitted a bespoke low-capacitance phono cable, which uses an advanced phono plug assembly. This has only two parts to minimize joints and incorporates a twist and clamp design locking the plug to the terminal. The design increases connectivity and ensures the signal path is kept as clean as possible.

Magnesium and Phenolic - Dual bracing
A super lightweight plinth combined with a double brace mounted specifically where the increased rigidity is required (between the tonearm mounting and the main hub bearing) forms a structurally sound "stressed beam" assembly. This design prevents energy absorption and unwanted resonances which will add un-natural distortions to the music. The RP8 takes Rega's double brace technology to the next level. Not content with an unprecedented stiffness to mass ratio, Rega have obsessively reduced any resonant properties by using two different materials for the new stressed beam. The top layer is magnesium and the bottom layer is pheno-lic (two of the lightest and stiffest materials available). Incorporating two different materials into the brace structure lowers their ability to pick up unwanted airborne vibrations. Simply put, different materials have different natural resonances. By using two different materials together they decrease the natural frequency of each other by self damping.

Super flywheel effect triple layer glass platter
The new RP8 three piece laminated glass platter is the result of a collaboration with a small, emerging, young British glass engineering company. As a general rule the only part of a turntable that requires extra mass is the turntable platter in order to achieve constant rotational speed. However a heavier platter creates more problems for the main bearing design so again an ideal compromise creates the best solution. Practically this means keeping as much of the mass to the outside rim of the glass platter to create more flywheel effect but keeping the inside of the platter as light as possible without sacrificing stiffness. The RP6 was the first Rega turntable to use a precision engineered glass ring laminated to the outside using modern CNC techniques to ensure concentricity. The RP8 takes it one step further by laminating three rings together to produce the RP8 super flywheel effect glass platter - an engineering triumph!

Skeletal plinth design with polyolefin foam core
Controversially Rega has always researched methods of producing light but stiff and rigid plinths. The technology is simple: unwanted noise at microscopic levels is developed by the turntable motor and main bearing. The plinth can also pick up airborne vibration from the music. From the beginning in the 1970’s Rega pioneered the use of a stressed skin structure for the plinth. This uses two layers of phenolic resin with a lightweight particle or fiber board sandwiched between the skins. This technique has been used in many applications where stiff, light structures are needed such as an aircraft wing or a Formula 1 chassis. The current increase in interest in turntables has allowed Rega to research and develop higher technology structures for the customer who is happy pay a little more for higher sound quality. The all new RP8 turntable utilizes a unique new stressed skin structure produced from thin phenolic skins sandwiching a featherweight nitrogen expanded, closed cell, polyolefin foam core. This material has been developed exclusively for Rega over a three year period. The RP8 plinth is 7 times lighter than the weight of the original Planar 3 plinth. Rega has added even more stiffness in the crucial area between the arm and the main bearing.

De-coupled outer frame and dust cover
A common problem for many skeletal design turntables is the inability to incorporate an effective dust cover into the design. Rega have constructed an outer frame that minimizes contact between the inner and outer plinth. The only points of contact are three location devices on the feet which centralizes the inner and outer plinths perfectly. This makes set-up extremely easy and allows the use of a dust cover. The RP8 can be used without the outer frame if so desired.

Turntable design & mythology
Today there are many approaches to Hi-Fi design which follow established and informed engineering or electronic principles. Amplifier and loudspeaker design has been well documented over the years with excellent technical publications. These subjects have been based on tried and tested acoustic criteria and many computer software programs now exist that enable a near amateur to design a passable working loudspeaker based on known acoustic and mathematical parameters.

Enter turntable design: When it comes to turntable design we are limited to a few poorly informed articles describing only very limited aspects of design. This is a subject full of mythology. Designers propose theories that counter the basic laws of physics, use terminology that doesn’t actually exist in the engineering world, build products that are more like beautiful sculptures than acoustic reproduction machines and sell items costing tens of thousands of pounds that hardly function as intended and often fail to work at all.

For instance a very common myth is "the heavier the better" concept. Turntable bases weighing tens of kilograms are not uncommon. The reality is that the base actually needs to be as light as possible to prevent unwanted bearing and motor noise being transferred to the turntable or record. Platters also fall under a similar myth with many platter designs becoming so heavy that it is impossible to design a correctly functioning bearing (and some so light that anyone can hear the speed inconsistency). The turntable platter itself needs to be of enough weight to spin at a constant speed within the confines of the chosen bearing and motor drive system.

Many amateur designers in any field choose one component in a design and try to achieve an extreme in size, weight and quality. They believe that by taking one theory to its extreme the design will become "perfect". The reality of all engineering, design (and life) is that perfection is not possible. Based on this reality, Rega's goal has always been to optimize a mixture of numerous "correct compromises" thus bringing the designer nearer to the unachievable goal of perfection.

24V Low noise motor
The motor is a high specification, 24V twin phase synchronous unit which has the anti vibration circuit hand tuned to each motor and is controlled by Rega's unique and innovative TTPSU power supply. The motor drives the CNC machined pulley and sub platter/hub-bearing assembly via the belt drive.
