Jcarr -- with all due respect, I think you have it all backwards ;--( Here's some technical background for your edification. BTW, the new core material only helps improve the signal to noise ratio, it doesn't increase the output:
The moving coil cartridge has become to be accepted internationally as the ultimate transducer of these and other fine analog recordings. However, despite increasingly sophisticated cartridges being developed there remains a number of aspects that place a ceiling on the quality of the reproduction: the prime cause being the yokes and pole-pieces of the magnet, which focus the field around the coil. The yoke system is unable to focus the full power of the magnet into the coil affecting both the strength and the accuracy of the signal. The resulting distortion inherent in most moving coil designs shows as a high frequency rise, ringing and a high level of both distortion and tracking distortion. There is also a masking of the frequency response, especially in the high range. The inter-relationship of magnetic field and coils is simply too "loose". The magnet and coils are too far apart to be able to capture the very subtlest details. On the other hand, very dynamic passages tend to cause coil saturation, especially if the coils are wound on formers. Increasingly powerful magnets, or special coils, bodies and suspensions, are in themselves no solution.
"Accuracy" defines precisely the ability of a cartridge to recreate the original recorded sound. Greater accuracy provides more of the music - the direct sound, and the myriad of recording environment subtleties that are the intimate detail. Ultimately, a more musical sound. Indeed, it seemed the ultimate moving coil design was already with us. Only to be continuously re-refined.
Design Concept
Now, in these final days of the glories of analog, there is a whole new frontier to the music of recorded music. The great complexity and crudeness of magnetic fields, yokes and coils is replaced by a new concept. The vast and costly magnets, magnetic-field-dispersing yokes and coils suffering variable magnetic influences of all other moving coil designs are replaced by a single assembly.
No yokes
Coils inside the magnet
No magnetic irregularities
Coils at the crux of magnetic focus
Intimate coil/magnet coupling
Low internal impedance
High output
Elegantly simple body design
Technical Features:
Unique ultra grade SS-µ-metal core for coil assembly. Newly developed ultra grade SS-µ-metal square core increases sensitivity by 35dB, improving the signal to noise ratio and eliminating a usual source of distortion.
Special 7N copper coils. A newly developed 7N copper wire used in the coils eliminates a common source of distortion and increases transparency.
Push-pull damping. A special quality compound has been meticulously designed and fabricated to provide total stylus/coil alignment and control. Its non-sensitivity to temperature change keeps the damping co-efficient stable and improves trackability.
Anti-resonance cartridge body shape. A resonance controlled 'simple' design for lower tonal colouration and a new-generation image.
Boron cantilever. Newly developed rod for a more natural sound.
Low mass tip. Ogura PA (3 x 30µm) tip. Its function is to reproduce the character of the original recorded sound - not add or subtract its own deficiencies.
Ultra tight magnet-coil coupling. The coils are not just close but literally right inside, with coil-magnet proximity of only a few thousandths of an inch. With the precision magnetic field focusing possible only with a ring magnet and superbly accurately wound coils, the ultra tight magnet-coil coupling enables far greater electromagnetic efficiency.
Dynamic mass minimized and coil saturation eliminated. Much faster, more accurate stylus response to groove formation. Rising dynamics or sharp transients never mask detail.
Twin coils on cantilever fulcrum. Ultra low dynamic mass and mechanical impedance for instant, accurate reaction to every groove detail, including the ability to handle massive transients without overshoot or break-up.
