Offering the Highest Level of Performance from a Rega Turntable
With the much anticipated RP10, Regaís advances its design philosophy further than ever before with sophisticated components built around its radical new plinth design. Featuring the brand new RB2000 tonearm, a ceramic flywheel-effect platter, and the custom RP10 power supply, the RP10 offers the highest level of performance from a Rega turntable to date.
Highly Evolved Power Supply
Housed in Rega's custom design case is a brand new, advanced anti-vibration and speed control circuit dedicated to running the 24v low noise motor. The speed and control of the motor is achieved by using a new DSP (digital signal processing) generator built upon a high-stability crystal. The device will divide the accurate square wave from the crystal to the exact frequency required to turn the platter at the selected speed. The DSP core will also generate a near perfect sinusoidal waveform to power the motor. Factory-set vibration and speed adjustments are then made to the power supply to tune the motor for optimal performance.
Feature-Packed RB2000 Tonearm
The included RB2000 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 RB2000 uses improved bearings, and each one is hand selected to be a perfect fit with the paired spindle matching both the inside and outside diameters. This is a Rega-developed method of increasing the amount of detail retrieved from the record surface, designed specifically to maximize the performance of the tonearm and cartridge.
The entire tonearm structure is designed to have the minimum of mechanical joints while using the stiffest materials in all critical areas. The tolerance of the RB2000 tonearm is so tight that no adhesive is used at any point throughout the construction. A brand new low mass, precision engineered, vertical bearing assembly further enhances the performance.
The RB2000 uses the latest award-winning Rega arm tube, which has been completely redesigned to redistribute mass and further reduce stresses and resonances. This advanced tube increases the stiffness and rigidity of the overall assembly while reducing stress on the bearings even further. Each arm tube is meticulously hand polished, keeping mass to an absolute minimum.
Magnesium and Phenolic Dual Bracing
A super lightweight plinth combines with a double brace mounted specifically where the increased rigidity is required, between the tonearm mounting and the main hub bearing. This forms a structurally sound 'stressed beam' assembly, preventing energy absorption and unwanted resonances.
The RP10 takes double brace technology to the next level. Not content with an unprecedented stiffness-to-mass ratio, Rega has 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 phenolic. These are two of the lightest and stiffest materials available.
Different materials have different natural resonances. Incorporating two different materials into the brace structure lowers their ability to pick up unwanted airborne vibrations. They decrease the natural frequency of each other by 'self damping.'
Super Flywheel-Effect Ceramic Platter
The RP10 uses a custom ceramic flywheel-effect platter. It is produced from ceramic oxide powder which is compressed, fired, and diamond-cut to ensure perfect accuracy and flatness across the surface. The new platter features a modified construction over the previous P9 version with improved coupling to the sub platter.
24-Volt Low-Noise Motor
The motor is a high specification, 24V twin phase synchronous unit. It is controlled by Rega's unique and innovative RP10-PSU power supply. The motor drives the CNC machined pulley, sub platter and hub-bearing assembly via the twin belt drive. Each motor is individually hand tuned to its own custom power supply in the factory to minimize vibration, motor noise and ensure optimum performance.
Skeletal Plinth Design with Polyolefin Foam Core
Rega continually researches 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 its beginnings in the 1970s, Rega pioneered the use of a stressed skin structure for the plinth. This uses two layers of phenolic resin with a lightweight particle board or fiber board sandwiched between the skins. This technique has been used in many applications where stiff, light structures are needed, such as with 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 RP10 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.
As a result of the ongoing research, the RP10 plinth is seven 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.
Decoupled 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 has 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 centralize the inner and outer plinths perfectly. This makes set-up extremely easy and allows the use of a dust cover.
The RP10 can be used without its outer frame, if so desired.
Optional Apheta Moving Coil Phono CartridgeThe Rega RP10 can be ordered with the acclaimed Apheta moving coil phono cartridge. Moving coil aficionados have been on a long search for super clear high frequency combined with firm tight bass. Such a cartridge would be the holy grail of moving coil cartridges. But the search is over now. The grail cartridge exists, and its name is Apheta.
When customers asked Rega to produce an MC cartridge, Rega's engineers began by analyzing existing designs on the market. They were astonished to discover that 99% of the products followed the same design principles established almost 50 years ago when materials and manufacturing processes were far less advanced than today.
"Stunning Spatial Performance"
"I noticed from the start that the Rega's spatial performance was stunning," reports Art Dudley in the December 2006 issue of Stereophile magazine. "I heard imaging effects throughout XTC's Skylarking that had completely escaped me in the past."
"Forget the foxy measurements," suggests Paul Messenger in Issue 47 of England's HiFi+ magazine. "Just dig the sound and the music delivered by the most interesting new cartridge Iíve heard in years!"
Conventional MC cartridges utilize a steel suspension system (tie wire) which creates a high amplitude H.F resonance (normally around 8-12Khz). Such resonance is unacceptable and is usually damped by a rudimentary piece of foam rubber. However the foam rubber deteriorates with age and cannot prevent the complete structure from vibrating and "ringing."
The specifics and adjustment of the tie wire and damping determine whether the cartridge is under damped (bright) or over damped (warm and bass heavy). A happy medium is rarely achieved.
This encouraged Rega to pursue a new direction inspired by modern materials and the basic laws of magnetism. The Rega Apheta contains neither a tie wire nor a foam damper. After four years and many hundreds of experiments. the innovative design of the Apheta was complete.

"It's too early in this product's history, and my experience with it is too limited, to say that the Rega Apheta will always perform better into an active device than into a voltage-gain transformer, but that's certainly how it sounded to me: The Apheta sounded better driving the perennially recommendable Linn Linto phono preamp (input impedance: 150 ohms) than the EAR 834P, either with the latter's own transformer stage or my external Tamura TKS-83. With the Linn, for instance, piano chords sounded much more real: more forceful than with the trannies, but not at all hard or glassy."
