Apheta 3 Pushes the Moving Coil Design Envelope
For more than fifteen years, Rega has been perfecting its unique moving coil cartridge designs. Rega pioneered undamped micro mass generation systems coupled with high integrity jointless bodies. In recent times, the company has achieved new levels of power from rare earth magnets. This fifteen-year evolution using the latest technological manufacturing processes led to the hugely successful Apheta 2.
With the Apheta 3, Rega has pushed the envelope once again. For several years Rega has been developing state-of-the-art diamond profiles of a "Fine Line" design mounted through 90 degrees (the same technique used in the Aphelion reference model). This work has resulted in Apheta 3 extracting even more detail from the record grooves.
Super High-Powered Neodymium Magnet
Apheta 3 features a super high-powered, neodymium magnet and a coil meticulously hand wound on an iron cross that is fifty percent smaller than the MK1 model. This weight reduction delivers greater freedom to track the vinyl groove.
The Apheta 3 is housed within a completely redesigned, single piece, aluminum anodized body and protected by a CAD designed, smoked rigid cover to protect the internal fine wires, making handling while installing it safe and risk free.
The Apheta 3 is the perfect partner for the latest Planar 8 and Planar 10 turntables. It will excel with any premium turntable, too.
Rega Moving Coil Cartridge Design
Rega’s moving coil cartridge design is unique in its approach to achieving an ultra-low mass generator which is undamped (no tie wire). It uses a unique rhomboid pivot for the cantilever powered by a purpose-designed, exclusive-to-Rega Neodymium magnet system. This type of design requires a zero-tolerance engineered cartridge body, which is Rega’s area of expertise and with the Apheta 3 these bodies are machined from one piece of the highest quality aluminum. This is a difficult and expensive process requiring all of Rega’s years of experience to achieve. In particular, the “zero” tolerancing of the body is required in the alignment and dimension of the pivot pad mounting hole and the magnet mechanism mounting hole relationship.
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 Apheta 3 contains neither a tie wire nor a foam damper. Moving coil aficionados will all appreciate the super clear, high frequency response combined with firm, tight bass. These are characteristics which all Rega moving coils exhibit.
