beltcat.jpgThis is a simple device created with a plain rectangle of white paper pricked with 5 pinholes, then an Aspirin tablet is placed over the centre hole, and a picture of a cat is slid underneath. See? Simple! Yet this technique has proven to be one of the most controversial ones ever, not to mention one of the most ridiculed. That’s why it’s one of my favourites! I’m sure the use of the Aspirin and the cat has a lot to do behind the reason why it incites so much mockery from the naysayers. There’s something about those things that really sparks the imagination in people. Those tweak-bashers who haven’t dismissed it outright as utter nonsense or “urban legend”, and try to find links to its method of operation, fail every time by applying common logic. But if “common logic” is all you have to work with, naturally that’s all you will use. If the uncommon audio engineer named Peter Belt approached everything in audio with “common logic”, the entire phenomenon known as “Beltism” would never have happened. So for me, this device exemplifies the genius of Peter Belt rather well. Did you guess how it works yet?  Hint: .niap morf modeerf ,niripsA eht dna ,trofmoc stneserper tac eht ,selohnip eht gniretne thgil neewteb pihsnoitaler a s’erehT Simple!

PROCEDURE:

Cut out a small rectangle from a piece of blank white paper. Poke holes with a pin near all 4 corners, and a fifth one in the centre, on the diagonal of the corners. This is your basic first layer, but it is a device in itself, it will have an effect. We are going to compound the effect by placing an Aspirin tablet over the centre pinhole (the tablet is also a device in itself), and go even further by placing a small picture of a cat underneath the piece of paper (yes again, the picture of the cat is a device in….). Now you have created the official “5-pinhole paper device”. So where are you going to find a picture of a cat, now? Try saving the one at the top of this page and printing it out. Out of 9 or 10 pictures, it was the best sounding cat!

PLACEMENT:

This device is most effective on wood, and as such, is commonly applied to speakers. But it can have an effect on other objects as well. Therefore, if its a flat surface, you only need to lay it on the surface. If not, you tape it to the object. Use a single piece of scotch tape, placing the tape across the paper and over the centre where the aspirin is, to secure the aspirin. I suggest starting with the back of speakers, near the terminals where the wire enters. As with most of these techniques, the more 5-pinhole devices you apply, the greater the combined effect.

VARIATIONS: You may also tape one to the centre of speaker wires and interconnects, or wooden furniture (especially if you’re one of those who think it might possibly have a direct effect on the signal!).

I feel most audiophiles should be able to detect changes effected by a single installation of the 5-pinhole device (I know a few skeptics who have), and most people should be able to pick out differences from many installations. But as with everything in audio, your mileage may vary!
