Rega Apheta MC Phono Cartridge

Description

Apheta moving coil cartridge.

The use of new magnetic materials and engineering techniques has allowed Rega to design a completely new generator system making the Apheta totally unique and our most innovative cartridge to date.

When asked by our customers to produce an MC cartridge we decided to analyse existing designs on the market. We 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. 

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 4 years and many hundreds of experiments the innovative design of the Apheta was complete.

Moving coil aficionados will all recognise the long search for super clear high frequency combined with firm tight bass. 

The search is now over.
