auricap XO High Resolution Capacitors

Auricap XO precision wound high resolution metalized polypropylene capacitors, made by Audience U.S.A. Specializing in OEM service for the finest designs.


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.

“As a hobbyist, I’ve been using Auricap capacitors in my tube amplifier projects for years.  That’s because they always work well, sound great and never disappoint. Recently I bought some Audyn True Copper Max capacitors and I am disappointed.  These were not meant to replace Auricap XO capacitors in my projects, just bought for comparison. After 20 hours of breaking in, my amplifier exhibits a somewhat strange, bloated midrange. I’ll give it more time but if they fail to satisfy,  they will be replaced with Auricap XOs. Years ago, I built a large 6CA7 based stereo power amplifier; all coupling capacitors are Auricap XO.  It came back for minor servicing last week.  After service I did some critical listening.  Absolutely marvelous. My automotive tube amplifier project (using Auricap XO capacitors) reproduces sound I only dreamed about in a car. It got terrific magazine reviews. Congratulations on a fabulous range of products.” Sincerely, Stephen Nitikman 
“I wasn’t sure how you can improve upon something that is so good already – the original Auricap. Was I in for a nice surprise! WOW! The best I can describe the new XO compared to the older design is like listening to a regular copper cable and then to a very pure OFC high-end cable. Everything is improved, but most dramatic is the naturalness combined with extreme 3D detail and air resulting in a bigger soundstage, yet so smooth and relaxed. Congratulations on developing such amazing capacitor, once again!” Best wishes, Alex Peychev
“After maybe 30 hours of musical burn-in, your Auricaps 10uf are truly fantastic! I tried the 1uF XO but finally I easily kept the 1uf Aura-t on my tweeters … Not really astonishing :–)) but the 10uF XOs has replaced with success a well known and highly regarded stacked copper capacitor. I can’t imagine what a 10 uF Aura-t would be capable to do…Just a dream, sad…Nevermind, the Xos are nice too. You know, I still like very much my stacked cast caps but in my current speaker system and also in my Naim amp, your Aura-t and XOs work clearly better for my wife and me, without any doubt and for 30 years, I tried so many high end caps…but never yours till today. Your caps are highly performing and I appreciate over all, their neutrality and their transparency. We can listen every kind of musics from jazz to death metal. (from Jazz at the pawnshop (1976) to Nile today !) I thought that metal music recordings were often very harsh but the Aura-t and also the XOs are able to reproduce the complex textures and amplitude nuances from a saturated guitar without any simplification, the result is a precise, detailled and quite soft timbre for this kind of music (of course) but no shouty sound.Metal with its high compression rate is a difficult challenge for caps and transducers but your aura-T and Xo can easily do it … Today, I am 50 years old and my favourite music is most of time classical, barocco and jazz but sometimes I still like listen to metal and my system today can be as good with these different style of music.” Kind regards, FREDERIC GRANGER DIY customer from Switzerland
