"Magnets on BlackDiscus
==================
I've been doing some experiments with magnets and BlackDiscus. Not sure if any products will come out of this yet, but it does open up a very easy way of experimenting and possibly enhancing your BlackDiscus (real ones or samples).
All you need to do is to put a magnet on top and listen. Doesn't really matter what type of magnet - you could use small neodymium magnets, or even fridge magnets.
Now I don't have the gear to be able to analyze in detail why this effect occurs. But my best guess is this the magnet biases the magnetic domains in the BlackDiscus. This means that the small field variations caused by nearby currents, etc, are swamped by the magnet's field. This means that the direction (N-S) of the field does not 'flip' to (S-N). The region around the zero cross or 'flip' is non-linear - this is the same sort of reason that bias is used in tape recording heads.
The effect you get is quite variable- sometimes it makes the BlackDiscus much better, improving just about everything and audibly lowering the noise floor. Sometimes it makes things sound terrible.. put magnets too near to varying currents (or transformers) and they start to wobble - then it's anyone's guess. But it's worth a little time experimenting - you may be able to get a big performance improvement for almost nothing!"
