The Audio Note™ copper audio signal capacitors have a superb sonic character, they have a life, colour, lack of harshness and evenness of dynamic behaviour across the frequency range. Recommended as replacements in old and new valve amplifiers alike (and even in the odd transistor amplifier), and essential for DIY projects.
The larger value capacitor are also suitable for either speaker crossovers or power supply applications. Those above and including 75mm in length are very heavy and should be mounted with suitable care to prevent the lead out wires breaking in transport.
Note well, that the body of these components are conductive and will effectively short two points that touch the body, so in some cases you may have to insulate the component with insulating material such as electricians tape.
Our signal capacitors are marked with a line on the right of the component`s body, this marks the start of the foil. It is my experience that the Audio Note™ sound the best when the start of the foil is "facing" the incoming signal, see the drawing below.
The silver foil capacitors have 99.99% pure silver foil, 20 strand silver litz leadouts and solid non-magnetic copper case. They use a fine mylar film instead of a paper in oil dielectric, we have found this to be the best compromise between sound and reliability, and those of you who have tried these copper encased silver foil signal capacitors can confirm the fact that the new Audio Note™ silver caps are better by miles than anything else, no mean feat when you also look at the prices, the only possible improvement over the Audio Note™ silver signal capacitor is an interstage transformer, which removes the need for a coupling cap altogether.
Mcap Supreme Silver Gold Oil
The MCap® SUPREME silver/gold/oil is definitely the top of the line model of our oil impregnated capacitors. In comparison with the Silver/Oil version, it technically features a further extended lifetime. More importantly, sonically the Silver/Gold/Oil version stands out with its wonderful natural voice and exceptional micro-dynamic. Truely amazing.
Mcap Supreme Silver Oil
The MCap® SUPREME silver/oil is an oil impregnated metallised polypropylene dielectric capacitor. As the name indicates, high-purity silver is used for the capacitor coating, and the winding is impregnated with a special oil developed in an exhaustive series of experiments and listening tests. Both these features contribute to a fuller and smoother tonal richness and diversity. Our state-of-the-art metallised polypropylene foils make it possible to maintain extremely low production tolerances that cannot be achieved with traditional oil/paper capacitor designs.
This is also the first time that the benefits of oil-impregnated capacitor design have been successfully combined with the well-known long-term stability of metallised paper and internal series wiring for induction-free SUPREME performance. Its lively reproduction of music impresses in particular with its subtly dynamic speed, precision and marked fine detail.

Mcap EVO Oil
The new EVO, range of capacitors from Mundorf incorporate their amazing EVOLUTION winding technology. This features an unusually narrow but tall capacitor reel. This format results in two benfits over the normal dimensioning of capacitors. Firstly, as a shorter width is required the signal path between the huge contact areas is greatly reduced, thus an extremely low equivalent series resistance/ESR is achieved. Secondly, in order to achieve the same capacitance the number of paralleled windings is larger than with regular caps, thus an minimized equivalent series inductivity/ESL is achieved.
The winding process is incredibly precise, the reels are spooled by hand in especially developed housing. Resulting in near avoidance of vibration and microphonic effects during the winding process. Furthermore Mundorf use the purest Polypropylene foil vaporized with the thickest metal layer possible. The Capacitors are manufactured with one leadout larger than the other to allow for horizontal and vertical mounting, the shorter lead also indicates the caps outer foil.
The MCap EVO Oil combines the magic of the MCap EVO‘s sound characteristic with the acoustic advantages of oil impregnated capacitors. Furthermore, the oil verion has an additional wrapping process. The screen print on the can comes in red giving it an appropriate quality look.

The MR range of capacitors is the result of an extensive ground breaking 2 year research programme into audio grade capacitors.
The resulting capacitor is at the leading edge of today’s high quality audio grade capacitors The component is manufactured in such a way to substantially reduce the negative effects of resonance on sonic quality which is inherent in a wound component. This results in a sonic characteristic which is difficult to equal. Manufactured from metallised polypropylene film the component is housed in a coloured acrylic tube and encapsulated in an epoxy resin to assist in the overall sonic performance.
Building on the success of their high end range of MR capacitors, Clarity Cap have launched the all new CMR range. As with the MRs they are manufactured in such a way to substantially reduce the negative effects of resonance on sonic quality which is inherent in a wound component. This results in a sonic characteristic which is difficult to equal. Manufactured from metallised polypropylene film the component is housed in a coloured acrylic tube and encapsulated in an epoxy resin to assist in the overall sonic performance. Connection of capacitor electrodes to the leads has always relied on thermal arc spray of tin-zinc, which results in hundreds of thousands of oxidised grain boundaries introducing; distortion and phase shifts at boundary crossings and increasing propagation impedance with diameter. CopperConnect technology introduces an embedded copper lattice to the end connection, dramatically reducing grain boundary crossings and signal path resistance, freeing capacitor designs achieve new levels of audio performance. CopperConnect technology dramatically reduces grain boundary crossings in the end connection and enables designs to employ narrower films for reduced capacitor ESR without introducing the corollary increase in end connection impedance. The philosophy of eliminating as many crystal boundaries as possible is extended to the use of premium grade 1.0mm2 tinned oxygen free copper leads. We are confident you’ll agree ClarityCap’s commitment to innovation has once again raised the bar for audiophile film capacitor performance.
ClarityCap have been manufacturing high quality audio grade capacitors in the UK for the last 20 years, The ESA range is a step up from the SA range, building up from the knowledge gained during the extensive research programme recently undertaken by ClarityCap.
The research programme looked into ways of reducing mechanical resonances inherent in a wound capacitor to hitherto unachievable levels. ESA capacitors are designed to offer a mid way house between the highly regarded SA range and the new no compromise MR range. Manufactured from polypropylene film the component is supplied in the familiar wrap and end seal style, wrapped in a polyester tape and encapsulated in an epoxy resin. They are available in both 250Vdc and 600Vdc ratings.
Building on the success of the popular range of ESA capacitors from Clarity Cap they have launched the all new CSA range. They are constructed using the same winding method as the ESA, manufactured from polypropylene film the component is supplied in the familiar wrap and end seal style, wrapped in a polyester tape and encapsulated in an epoxy resin. However, the CSAs differ in how the lead outs are joined to the capacitor electrodes.

Mica capacitor is a capacitor using mica which is a natural mineral as a dielectric. By using mica, the heat resistance becomes ober 600 degrees, creating an excellent temperature characteristics. In addition, since the capacitance temperature coefficient is small, constant and highly accurate, there are almost no aging deterioration. Also, since the dissipation factor and the dielectric loss are very small and high frequency characteristics are excel, it is often used for circuits requiring high precision and stability such as signal equipment, medical equipment, and high frequency circuits. In recent years, the natural mineral mica has been highly valued for producing an excellent sound quality with transparency. Several major sound equipment manufacturers have adopted for its vacuum tube amplifier and power conditioner, attracting many fans of sound equipments as a capacitor with particularity..

Jupiter copper foil wax & paper capacitors go far beyond a mere copper foil version of the standard tubular HT Aluminum design. Every aspect of the capacitor construction was evaluated during the 4 year development process. Even the smallest details were addressed which resulted in significant improvements in sonic performance.
Wax with very special sonic characteristics, better damping and thermal characteristics was chosen as a perfect match. Further, new lead termination technique has allowed the music to flow more naturally. Without exception, every detail has been tailored to this specific copper capacitor design. After four years of refinement Jupiter Copper Foil capacitors are here.
Life like vibrance gives the feeling of presence, along with micro-detail, holographic bass, and aural decay that is disarmingly natural, the ears will know immediately.
The line on the label indicates the outermost foil, and should be connected to the lowest impedance path to ground.

Auricap XO is a new high performance capacitor product from Audience that is the result of rigorous consideration of every aspect in capacitor design and the manufacturing process. Audience has reconsidered a host of parameters including tension windings, baking times and cryogenic treatment among other proprietary procedures. Auricap XO is made using the very finest obtainable polypropylene film and new high purity continuous cast copper leads. This new capacitor design offers reduced parasitic such as ESR improving on its effective bandwidth, clarity and coherence. With these design changes a new level of performance is reached with even less coloration, micro-phonics and noise contribution than the famous Auricap. There are no drawbacks to the Auricap XO in comparison to the standard Auricap. Users can still expect all of the wonderful virtues for which the standard Auricap is known. In brief, the Auricap XO is simply more transparent allowing you to hear farther into the music.
