| The
Moving
Coil cartridge Apheta The
Story
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.
