AUDYN True Silver
The Audyn True Silver are a high performance audiophile capacitor. They are a silver metallised polypropylene capacitor, with pure silver lead outs. They are a bifilar design so are non-inductive, they are a self healing design.

AUDYN Cap Reference
The outstanding features of Audyn cap Plus are exceeded by Audyn cap reference.
More details and more dimensionality in music. Very long term stability, mechanically stabilized, vibration free shed, induction free, selfhealing construction, contact surface on both ends specialy treated with sulphate granulation special copper plate connection at both ends guarantee perfect connection. This leads to better connection compared to usual connection with simple solder. Better and bigger surface with Tritec wires leads, stable housing, low loss factor, an absolute top quality high end component.
AUDYN Cap Plus
Polypropylene capacitors are constructed with two separate polypropylene foils connected in series, bi-filar. Thus they are non-inductive with damping depletion.
These ultra-low loss capacitors have been developed for extreme impulse/power handling. An important design/constructional feature is the power handling of the connection between the foils (electrodes) and the end leads. The AUDYN CAP PLUS has a vastly improved system of connecting the electrodes to the end leads. AUDYN CAP PLUS also utilises an internal series connection system whereby layers of metal foil are combined with a one-sided metallized "blind" layer. As a result, the double metallization performance is greatly enhanced. An absolute top-quality component.
AUDYN Cap Q4
The Audyn Q4 is a high-quality film/foil capacitor, perfect for crossover components. It offers tight tolerance of ±5%, ensuring precision performance. The capacitor is built with a robust Polypropylene film that ensures long-lasting durability. It operates at a nominal voltage of 400V, offering reliable, steady performance across a wide range of applications. Furthermore, the capacitor features a low loss factor tang of 0.0020 at 1kHz, indicating high efficiency. Its tin-plated copper wire connectors ensure excellent conductivity for optimal performance. Whether you're building or upgrading audio equipment, the Audyn Q4 capacitor offers the quality and reliability you need.


Superior Z-Cap. Thông số kỹ thuật /Datasheet Superior Z-Cap.pdf
Super MKP capacitors are made with a double lane of metalized polypropylene foil, hence a double foil construction. By using special winding machines and winding techniques, two capacitors are connected in series within one capacitor housing, When making this type of capacitor you therefore need 4 times the foil used in standard type metalized polypropylene foil capacitors.
Compared to standard type metalized polypropylene foil capacitors, the Superior Z-Cap is on a higher audiophile level, where even finest nuance improvements can be heard.
Silver Z-Cap. Thông số kỹ thuật /Datasheet Silver Z-Cap.pdf
Where the Superior Z-Cap is made with pure copper lead-wires, the Silver Z-Cap is made with pure silver lead-wires, giving the Silver Z a slightly different sound “flavor” tailored to silver based component enthusiasts. Highly recommended for tweeters and mid-range application for high-end passive speakers and as coupling capacitors in tube and power amplifiers. The Silver Z-Cap is a metalized polypropylene foil capacitor but made as special construction we call a “Super MPK Capacitor”.
Standard Z-Cap. Thông số kỹ thuật /Datasheet Standard Z-Cap.pdf
The Standard-Z Cap is our entry level audiophile capacitor. It positions higher in our capacitor hierarchy above the Cross Cap, but below the Superior Z-cap.
It is a single foil standard type MKP capacitor that uses the highest possible quality aluminum based metalized PP foil. It uses the same foil as our Superior- and Silver Z-caps, but in this application as a single foil capacitor (single capacitor per housing).

Alumen Z-Cap. Thông số kỹ thuật /Datasheet Alumen Z-Cap.pdf
The Alumen Z-Cap is a high-end pure aluminum foil capacitor, designed specifically for passive crossovers (tweeters and midrange drivers). The usage of a thinner dielectric insulator allows for a capacitors with less “memory” and one that is much faster reacting.
The Alumen Z-Cap offers unparalleled value for money in terms of cost versus performance. Specifically designed for the tweeter and upper mid-range sections on passive crossovers.
Compared to the Superior and Silver Z-Caps (Super MKP /
double metallized polypropylene foil) capacitors, the Alumen Z-Cap will bring less brightness and a little more natural top end balance to your system.
Amber Z-Cap. Thông số kỹ thuật /Datasheet Amber Z-Cap.pdf
The Amber Z-Cap is a super high-end pure copper foil capacitor, designed specifically for passive crossovers. They are primarily meant for the tweeter section of crossovers but work equally well for upper mid-range application. The Amber Z-Cap builds on the same design principles of our already critically acclaimed Alumen Z-Caps. The differences between the two are subtle, but to the connoisseur listener, the listening experience will still be a clear improvement in the overall tonal balance. Copper foil gives the capacitor an even better sonic “flavor” compared to aluminum foil. The sonic “flavor” of copper foil is best described as giving an even more neutral/natural depiction of vocals and instruments compared to the Alumen Z-cap.


Cross-Coil Inductors. Thông số kỹ thuật /Datasheet Cross-Coil.pdf
The Cross Coil was developed in cooperation with Mr. Per Skaaning from Audio Technology (Denmark). It is a high-performance foil inductor offering improved power handling and dynamic head room. Using pure copper foil, we have insured a better surface for electron travel, a better distortion reduction, a higher power handling and improved dynamic headroom, compared to wire-based inductors. The coil is wrapped in clear shrink foil to protect the outer layer of foil and to help maintain the integrity of the windings.
Wax-Coil Inductors. Thông số kỹ thuật /Datasheet Wax-Coil.pdf
The Wax Coil is a paraffin-wax impregnated foil-based inductor. It is a high-performance foil inductor offering improved power handling and dynamic head room, compared to mainly single wire-based inductors, but also compared to litz multi-strand wire inductors. The wax impregnation protects the copper foil and ensures the integrity of the windings for decades of high performance. Using pure copper foil we have ensured a larger and better surface for electron travel and a great reduction in unwanted distortion.



ClarityCap ESA-CSA 250Vcapacitors

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.
Building on the success of the popular range of ESA capacitors from Clarity Cap they have launched the all new CSA range. Taking inspiration from the highly regarded ESA range, the CSA employs the same carefully researched micro-phonics reducing processing parameters. Copper Connect 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.
ClarityCap MR-CMR-PURS capacitors


Claritycap’s unique Copper Connect technology addresses a hitherto under explored area of audio capacitor performance. Copper Connect 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. Taking inspiration from the highly regarded MR range, the CMR employs the same micro-phonics series film construction and acrylic tube damping. Copper Connect 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.
ClarityCap PUR-S featuring • Silver-coated, multi-strand cable from Van den Hul® • 10mm CopperConnectTM technology • ±3% tolerance as standard enabling tight crossover control • High-gloss black outer, gold labelling & resin fill.
