On our last local DIY Audio gathering, we were provided with a free complimentary set of a new tweaking stuff. It was called Musicsnap.

On my imagination, this kind of tweaking stuff is similar with VTS Marigo Dot or something. Not so sure though, until we can have a further check.

According to the person distributes this free complimentary sample, the Musicsnap is based on the MDI (Micro Discharge Interface) distortion theory by Pierre Johannet. Although this theory receives many debates and controversies (due to most people current limited knowledge to prove it scientifically), many audio manufacturer actually already implement similar approach with MDI. Perhaps they don’t speak MDI directly, because most of the time, people would call you retarded if you are talking about something which you can’t scientifically prove (or only based on common audiophile geeks amazing word, “Oh, I hear the different!”).

But what they have done (and maybe after serious long listening test), proves that this kind of MDI approaches does make some different and significant improvement to the audio system. We leave the question “why and how” to the people who is interested (you can easily find those article – mostly in French – with “MDI” and “Pierre Johannet” keywords).

The manufacturer says that this Musicsnap best used on non-soldering join, like RCA connection, front face of speaker driver, volume control, etc. But it’s time for me (and most of the visitor of the gathering who received the sample) to check if there is really a significant improvement elsewhere.

Musicsnap has two sides: black side and the white side which has sticky tape on it.

Was a tough and tiring Friday. I want to listen some music (but I need to tweak some). Ok, fire up my iron and start to cook it right away.

If you don’t have any idea about my DIY speaker, feel free to visit here and here.

Ok, basically I just add 0.47uF K40Y-9 capacitor on my high pass filter. Current configuration is a little bit too bright on the tweeter, so I need to lower the F3 of my high pass filter. So here it is…

The high pass is 2rd order, combination of Siemens PIO and K40Y-9. Also Sfernice resistor used there. The inductor is Alpha Core Foil Inductor. Bought it few years ago, not the price is getting high and higher!

Actually, I don’t do iPod. But just for fun, why not?

This is actually an “old” audio tweak, by using this “stuff” below. You can buy it at local bookstore.

This removable adhesive could be place above your components, like capacitor, resistor, or even DAC and Crystal (Clock). The effect? Taste yourself, as I did on my iPod below.
