Goldring 2100
All Goldring 2000 series cartridges feature Moving
Iron technology. This lends them the high levels of detail associated
with more expensive moving coil designs whilst retaining the convenience
of a replaceable stylus and high output associated with moving magnet
types. The cartridge employs a fixed samarium cobolt magnet and high
output coil combination so that a very light iron/nickel cantilever
end-piece can be used instead of the much heavier permanent magnet used
in conventional designs. This reduces the moving mass allowing the
stylus to trace the record groove more faithfully. Because of their high
output, Goldring 2000 series cartridges should be used with the
standard moving magnet phono input of an integrated amplifier.
The 2100 features a bonded elliptical diamond stylus producing high
frequency clarity and quality sound. The 2100 can be used to upgrade
many budget turntables.
Moving "Iron" Generator
A diamond stylus tracing the average record groove will experience
accelerations of up to one thousand gravities. This means that in a
moving magnet design the permanent magnet is subjected to similar
accelerations and if its mass is too large its inertia will result in
poor transient response, distortion and mis-tracking of the stylus. The
2000 series cartridges use a fixed magnet design so that the mass of the
magnet is completely isolated by the compliance of the cartridge
suspension and a much smaller and lighter iron/nickel alloy tube can be
used instead. Attached to the cantilever, the alloy tube is used to
perturb the stationary magnetic field provided by the large fixed magnet
and thus provide the changing magnetic flux necessary to generate the
signal voltage in the coils. Modern samarium cobalt magnets have a super
high energy output and so a much lighter magnet can be employed than
ever before giving the completed assembly a similar mass to traditional
moving magnet types. In this way the cartridge enjoys the convenience
and flexibility of a traditional moving magnet design with a replaceable
stylus block and a high output compatible with standard MM input
stages. At the same time it enjoys some of the refined sound and detail
retrieval previously only available from more costly moving coil
designs.
Threaded Inserts
The cartridge body benefits from integrated M2.5 threaded mounting
holes which means that it is very easy to mount onto the tonearm
negating the need for fiddly washers or nuts which need to be
counter-held during adjustment.
