STYLUS GUARD - 200 HOURS OF USE
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
analyze 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
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 recognize the long search for super clear
high frequency combined with firm tight bass.
The search is now over.
