Many music lovers go for a moving coil
cartridge when it comes to a precise and natural reproduction. After
all the record was cut by a diamond moved by coils. Others prefer
the sound of a moving magnet cartridge when they talk about high fidelity.
They find that a moving magnet cartridge has more speed than a moving
coil cartridge and therefor gives a better transient and is more pleasant
to the ear. If you have more than one turntable, you can of course
use both techniques.
Each
design has its specific positive features.
Yet
the moving coil adepts have it easier when the time comes to replace
a worn needle tip by a new one. For them the road to constant happiness
is a straight one. They just exchange their used cartridges for new
ones of the same brand, same type. And they will seldom be disappointed.
The
performance of the moving magnet cartridge is not always guaranteed.
Especially
when you are using an older cartridge for which original styli are
no longer available, you depend on the needle of a different manufacturer.
Generally these needles are not of the same quality as the original
ones. This is because the materials used are not the same as used
by the original manufacturer:
1) rubber
damper (suspension block),
2) magnet (how large is it and of what type, material),
3) the cantilever (how strong is it, of what material is it made,
what is the shape and mass),
4) and the parameters of the diamond tip. Is it a nude diamond, what
is its shape, what is the mass, and is it well polished?
If
you order a needle for a discontinued cartridge, be sure it is an
original specimen. If that is not available, check the functioning
of the replacement stylus and compare it to the original one, both
by eye and by ear.
It
is generally impossible that the replacement made by a different
factory will meet the standards of the original stylus. Bowadays
however most replacement needles are of good quality.
But
the difference in sound should not be too great. If a replacement
stylus does not perform well enough, you should contact the seller.
Of course, the suspension of the stylus needs a break in time. You
need more than one week. This is certainly true. The replacement stylus
does not show the qualities right from the moment you have put it
into the cartridge.
In
order to avoid these problems it is advised to buy a modern quality
cartridge of which original needles will be available for at least
another five years. Another option is to send the MM cartridge to
a service for a new tip placed at the end of the original cantilever.
That will guaranty another 2000 hours of enjoyable music listening.
Ask The Cartridgeman or Alt Jouk van den Hul for possibilities and
prices.
Burning
in and seasonal influences.
Each
new cartridge needs many hours of playing time to make the suspension
of the cantilever supple and bring the compliance of the cartridge
to the original values as specified by the manufacturer. In the beginning
the downforce will need a bit extra weight. After a week or so of
playing, the downforce can already be adjusted.
And
do not forget that the climate plays its role. During a hot summer
the temperature can improve the trackability of the cartridge and
you may choose a different down force. In autumn - and certainly in
winter - the downforce may need a little adjustment. It all depends
on where you live and the way you heat your listening environment.
