SID Sound Improvement Disc

SID Sound Improvement Disc

Improves the sound of CD, SACD, DVD –A & DVD sound & picture

The Sound Improvement Disc is an accessory that is placed on top of the CD , results in a better separation of instruments and a much clearer reproduction of the voice.

The SID is the easiest and the cheapest way to upgrade your HI-FI system.

The best way to hear the difference that the SID makes to the sound is to play a piece of well known music for a maximum of 30 seconds without the SID , and then the same piece with the SID in place.

All CDs are see through no matter if they are coloured or not. One only needs to take a small torch and hold it against the silver side of a CD to see that the light is visable through the disc. It is also possible to move the CD up to 1,3mm away from the laser. Being as the CD is only 1,2mm thick it shows that it is possible for the laser to actually see right through the CD. With this in mind the correction system reacts to the varying reflections it sees from the label thus giving the system more work to do than is necessary. With this in mind the sound will be very much smoother as it has hardly any interruptions induced by false information from the correction system.

The SID disc has a special matt finish on one side and this side is placed to the CD label so that the stray laser light is absorbed , the green colour changing the red light of the laser into black thus neutralising it.

The SID is only 0,3mm thick and 2,8gr. in weight so it will fit in virtually every player.

It is probably the cheapest way to improve the sound of CD that there is on the market.

The SID comes in two versions - model 14 for Philips and Sony Transports and model 15 for certain top loaders and Players with Pioneer stable Platter and Maridian 506+508

Why model 14 & 15?
There is a very good reason why the SID comes in two versions.
The model 14 is made for CD players with Philips and Sony type transports .These transports have got a spindle 15mm diameter with a cone so that when the CD is on the spindle it takes up 1,2mm in height (see sketch) thus reducing the diameter on top of the CD to 14mm diameter. The SID sits on top of the CD and fits exactly to the 14mm diameter so as to run concentric with the CD. (All other products on the market have a15mm hole which allows them run excentric which shakes the whole mechanism)

The model 15 is made for CD players which have a Pioneer transport where the CD is placed label side down on the turntable. This spindle has a longer parallel part and the SID must first be placed on the spindle - 15mm diameter matt side up then the CD on top.

The model 15 must also be used on:
