Sound
Improvement Disc
We've seen many accessory discs and foils, to be placed in
the loading tray
on top of the CD, some intended to mechanically damp the disc.
Most to put
it charitably, have been problematic in use and have given
mixed or dubious
results.
But Peter Boffin, a british engineer living
in Germany, has come up with a
precision made, extremly flat and thin CD overlay disc that
works. He
explains what SID does: 'If you hold a CD against the light
you will
discover that the print of the label in visible from the side
to be read
(by the laser). The label reflects the light of the Laser
with varied
intensity. Therefore one gets differing, reflections during
the rotaion of
the CD whilst information is being read. THE SID removes reflections
caused
by the label.'
As the error correction system has to work
less, he goes on, 'the music
will sound smoother. The vocals will appear as though a veil
has been
lifted from in front of them. Instruments sound more breezy,
concise, and
the sound is generally less nervous.'
The SID is placed on the label side of the
CD. There are two versions.
Model 14, with a 14mm centre hole, suits draw loading Philips
based
transports. Model 15, with a 15mm centre hole, suits Pioneer
'turntable'
Transports, Meridian 505 and 508, and most top loaders, for
example CEC,
Theta, Spectral, Jadis JP1, Einstein, Berendsen CD1, Cambridge
D300 and
D500. The SID is not suitable for use with CD magazine players,
portables
or car players. If in doubt, please state player make and
model when
ordering. Just try it! If it doesn't do what you want it to
within 28 days
we'll give you your money back.
