Crucial components of VNP Caps are made with some of the best sounding materials available:

  • Copper plates are hand-cut from Mundorf audio-grade copper foil
  • Insulator layers are hand-cut from finest natural silk fabric, and impregnated with cosmetic-grade linseed oil
  • Casing is made from solid pine wood
  • Leads are solid core tin-plated copper in waxed cotton insulation

The resulting sound is natural, airy and brimming with beautiful overtones.

Every VNP Cap is made to order. Studio Zy philosophy is to create things that are natural, beautiful and made by human hands, not machines - and as such, individual and unique.


Values available at the moment are anything below 100nF.

The current price for a VNP Cap in values below 1-15nF is 29. Values over 15nF are priced individually, depending on requirements (as a rough guide, every additional 10nF over first 15nF will cost about 3-5). 

Evaluation samples are available - please ask for details.

PayPal integration is coming; for now, please email me with your order and preferred method of payment - you will normally get a reply the same day.


VNP Cap is entirely hand-made, and it cannot possibly be made as consistently as mass-produced parts. Therefore, it needs some extra precautions:

Test before using
Make sure that the capacitor is working, before connecting it. It should exhibit no electrical connection between the leads (i.e. should be blocking DC voltage). Each one is measured and auditioned before sending, so they ARE working when they leave my hands. But as I have no control over the transit conditions, and the capacitors are quite delicate (despite their looks), I have to ask you to check them before use. This is probably a sensible thing to do with any component, really.

Voltage Rating
Most of the VNP caps should be fine for 100V or more - but because of the unavoidable variations in insulation thickness, the actual safe voltage can occasionally be much lower. They are recommended for use in low-voltage (under 50V) circuits only.

Temperature stability
Because of their relatively thick metal and wooden plates (and the thermal expansion phenomenon), VNP Caps react strongly to elevated, or very low temperatures, and are best kept in constant room temperature. Their rated capacitance is measured at 20 degrees Celsius. High temperatures will result in considerable capacitance increase, and in extreme cases, breach of the insulator layer and resulting component failure (short-circuit).

Also, in case it is not obvious: VNP Cap is made mostly of flammable materials. It WILL catch fire if exposed to open flame or extreme heat. It is NOT self-extinguishing.

Operating environment
Extremely high or low humidity environments should be avoided as they can cause the wooden casing to warp and result in capacity changes, and other problems, similar to the described above. Another reason to avoid high humidity is that non-metallic parts the capacitor may eventually develop mould, or start to decay - they are natural materials after all. This is unlikely however, as both linseed oil and resins naturally present in pine act as preservatives to some extent.

Manual adjustment
The casing mounting screws can be used to tighten/loosen the plates and thus adjust the value of the VNP Cap to compensate for the temperature drift. Please be careful and do not over-tighten screws as this can short the capacitor layers and/or cause the wood to crack.

From the designer

"I first started working on what became VNP Cap because I was looking for a capacitor to upgrade the critical Vref component in my "Shigaclone" CD player. I tried very many capacitors, including some respected (and expensive) makes, such as Black Gate, ClarityCap and Multicap - only to find that none of them could improve the sound over the stock, cheap electrolytic capacitor...

That seemed strange, especially that I was expecting the film capacitors to be superior to electrolytic. Something about this particular position was causing those audiophile capacitors to fail to deliver. Still, I was convinced that there has to be room for improvement, only that the commercially produced capacitors were for some reason not doing a good enough job.

If I wanted a better capacitor, I had to design it myself then... So I went back to the very roots of what a capacitor is: two metal layers separated by an insulator; that determined my choice of stacked foil geometry, which is the only "true" capacitor layout (or rather - is the least of a compromise). Then I researched the available materials, picked the best I could reasonably afford, then spent many long hours putting the whole idea together... Eventually I made the first prototype. When I installed it in my test setup, it impressed me so much with its natural sound that I named it "Very Nearly Perfect" capacitor.

I then experimented some more, until I was confident I could make them reliable and of consistently good quality. Finally, I abbreviated that rather immodest original name to a much more sensible "VNP" and so the VNP Cap was born."

"Special thanks go to the user nemo1968 from diyaudio forums, as his homemade capacitor first inspired me to start experimenting with my own capacitors."

Warranty & Disclaimer

All VNP Caps come with a lifetime warranty against manufacturing faults and defects. Their sound quality is also guaranteed - full refund will be given if you are not impressed with them.

Not covered under warranty are natural variations in materials and minor manufacturing inaccuracies typical of hand-made items.

My components are under constant development, so description and pictures may not reflect the current development stage.

Disclaimer: no claims will be accepted for any damage or loss, direct or implied, that arose due to the use of these capacitors, either in electric devices or elsewhere. Don't even think of installing them in military or medical machines.
Read the Precautions paragraph and above all - use common sense.
