Auricap XO Metalized Polypropylene Capacitors

The Auricap XO is a new high-performance capacitor product from Audience that results from rigorous consideration of every aspect of 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 finest, obtainable polypropylene film and new high-purity, continuous-cast copper leads. This new capacitor design offers reduced parasitic such as ESR improving its adequate bandwidth, clarity and coherence. With these design changes, a new level of performance is reached with even less colouration, micro-phonics and noise contribution than the famous Auricap.
There are no drawbacks to the Auricap XO compared to the standard Auricap. Users can still expect all of the beautiful virtues for which the standard Auricap is known. In brief, the Auricap XO is more transparent, allowing you to hear farther into the music.

Auricap no longer marks the outer foil of their capacitors. However, we may have older stock that has been marked - see below.

The following refers to older stock - Auricap film capacitors are not polarized. However, the outer foil is marked by a red lead out with a black mark or a black lead out or an "O" mark at the end of the capacitor body. Some of the stock now has white leadouts. These are marked on one end by a black circle, which indicates the outer foil end. This leads to the lower impedance end (lower DC voltage end). This will improve the noise floor.
