The Audio Note CAP-3290 is a premium 0.33 µF, 630 V copper foil capacitor designed to deliver the highest level of audio signal fidelity. Specifically crafted for demanding audiophile and high-end DIY audio applications, this capacitor features advanced materials and precise engineering for exceptional sonic performance. Its copper foil construction ensures remarkable clarity and musical detail, making it a top choice for signal path upgrades in both single-ended triode amplifiers and other audio circuits.
Audio Note CAP-3290 0.33 µF 630 V 10% Copper Foil Capacitor
Engineered for discerning audio enthusiasts, the CAP-3290 employs pure copper foil as its dielectric medium, which results in an unparalleled level of transparency and harmonic accuracy. This design choice, along with a robust 630 V voltage rating and tight 10% tolerance, makes it ideally suited for signal coupling and bypass duties in high-fidelity audio equipment. The meticulous production methods and use of improved dielectric materials ensure that every detail of your music is preserved with stunning clarity.
One of the standout features of the CAP-3290 is its copper casing, replacing the more common aluminium, glass, or plastic enclosures. This not only provides better electromagnetic shielding but also enhances the capacitor’s overall sonic performance by reducing unwanted resonances and microphonic effects. The result is a purer, more immersive listening experience that reveals subtle nuances in every recording.
Designed with both the single-ended triode amplifier market and broader audio applications in mind, the CAP-3290 is a flexible upgrade for any critical signal path. Its excellent sonic characteristics make it suitable for crossover components in high-end audio components, as well as in custom-built or upgraded amplifiers and speakers. The various available sizes and capacitance values allow for seamless integration into a wide range of audio circuits.
The Audio Note CAP-3290 is particularly appreciated by DIY enthusiasts and professional builders seeking an edge in their audio designs. Whether you are restoring a vintage amplifier or constructing a modern reference system, this copper foil capacitor ensures your components achieve new heights of musicality and fidelity. Its competitive pricing, combined with its remarkable performance, makes it an excellent value for any serious audio project.
