Amber Z-Cap Cap, 4.70µF 200VDC, 3% Tolerance

The Amber Z-Cap is a super high-end pure copper foil capacitor, designed specifically for passive crossovers (mainly tweeters). They are also equally well suited for mid-range application, but due to the price point of these super high-end capacitors, they will most often be used for tweeter 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 has a noticeable positive impact on the “flavour” of the sound. This “flavour” 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).
