Tja? Koster ikke skjorta og disse høyttalerne er fantastiske.
Jantzens beskrivelse:
The Alumen Z-Cap will offer a more “neutral” presentation in the overall sound in certain crossover designs, and by “neutral” we refer to the focus will be shifted from what can be a somewhat overemphasized brightness from a Super PP cap, being replaced with a more even balance between the depth of the midrange and the presence of the tweeter.

Technical specifications (according to manufacturer): "The Amber Z-Cap is a pure copper foil capacitor designed specifically for passive crossovers. 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 and instruments. This is paired with the enhancements in transparency and detail richness on an even higher level compared to metalized polypropylene capacitors. 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 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. Can also be used as coupling capacitors capacitors for transistor amplifiers. Dielectric: Polypropylene film; Construction: Four-layer round tubular type axial leads; Winding: Copper foil spliced to polypropylene insulation film; Rated Voltage: 200VDC / 160VAC; Electrodes: Pure copper foil; Contacts: Non-inductive zinc thermally sprayed extended film; Coating: Bronze plastic tape wrapped black resin, sealed in a copper colored anodized aluminum tube; Leads: Tin plated oxygen free pure copper."
Sound: In general (like all copper foil types) the Jantzen Audio Amber Z-Cap has a nice realism of tone, very convincing in the way it portrays vocals and acoustic instruments. The Amber Z-Cap is extremely neutral, nothing stands out (in a positive way) so I would group it with other very neutral copper foils like the Duelund RS and Audyn True Copper Max. Not quite as dynamic as the Rike Audio S-Cap nor as rich and lush as the Jupiter copper foils and Duelund CAST Cu-Sn, just simply middle of the road neutral which I find to be very pleasing when listening to a wide range of music types and recording qualities. Basically copper foil capacitors can be split into two camps, one that is absolutely neutral, the other that has a slightly more "character" to the tone. I would consider the Audyn Cap True Copper Max, Duelund RS, Jantzen Audio Amber Z-Cap and Miflex KPCU-01 to be very neutral. All Jupiter types, Duelund CAST series, Rike Audio Q-Cap have a bit more character or colour. It's up to you which suits your system and taste the best! I have added the Jantzen Audio Amber Z-Cap to my favourites list.
Verdict: 12,5
