✅ Best For:

• Tweeter and midrange circuits in ultra-high-end 2-way and 3-way systems

• Vocal and acoustic instruments, where nuance and realism matter most

• Upgrading boutique speakers (e.g., tube-based, high-efficiency designs)

PRODUCT FEATURES
The Amber Z-Cap is a super high-end pure copper foil capacitor, designed specifically for passive crossovers.
They are primarily used for the tweeter section of crossovers but work equally well for mid-range section 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 simply has a different sonic “flavor” compared to aluminum foil.
The “flavor” of copper foil is best described as an even more neutral/natural depiction of vocals and instruments.
This is paired with the enhancements in transparency and detail richness on an even higher level compared metalized polypropylene capacitors (MKP / Super MKP capacitors).
Due to the max. 200 volts DC voltage rating, we advise customers to be mindful when using Amber Z-Caps for tube/valve and power amplifier application.
For upgrading the coupling capacitors in amplifiers, we instead recommend choosing our Superior or Silver Z-Caps capacitors.

KEY INNOVATIONS
• An extremely fast reacting capacitor
• Ultra-thin dielectric insulation to eliminate memory effect in the capacitor
• Extremely low ESR, SEL, inductance and dielectric absorption data
• High quality pure copper foil wound with highly specialized machinery and precision winding techniques
• The center of the capacitor is enforced by small steel balls to further ensure stability and shape of the capacitor
• The specialized winding technique and overall quality of this capacitor enables us to offer a high-end product with a lot less distortion compared to the market standard
• Specifically designed for the tweeter and mid-range section of passive crossovers
• Can also be used as coupling capacitors for transistor amplifiers
