Als je nog heel erg twijfelt, dan zou ik in eerste instantie een Jantzen Audio Superior Z-Cap op dit plek zetten. Niet extreem duur maar stukken beter dan standaard spul. Deze condensator heeft een mooi neutraal karakter en het beeld komt lekker los van de speaker - een goed beginpunt dus. Bij goedkopere types blijft het beeld wat meer "plakken" aan de luidsprekers.
Vervolgens laat je alles inspelen en ga je lekker een tijdje luisteren. Dan kun je een persoonlijk oordeel geven over het geluid en kun je gerichter zoeken. Misschien vind je het wel mooi zo met die Jantzen's en kun je alles lekker laten zoals het is en koop je van het overgebleven geld een stapel LP's.
Misschien hou je van meer sprankel en diepte in het beeld en kun je denken aan een Mundorf Silver-Gold-Oil. Maar misschien zoek je nog tastbaarder en natuurlijker klinkende harmonische boventonen en kun je kijken in de richting van Duelund.

mooi man dat internet

vind ik zo maar nog een C-test

En nog een post over de VSF van Duelund, geen testje helaas

Mundorf SGO vs Duelund VSF
http://www.co-bw.com/Audio_High_End_Capacitors.htm
Toch af en toe maar eens wat hersencellen lastig vallen met wat mij een juiste keus lijkt. Als ik de, schaarse, reviews mag geloven dan staat de omschrijving van de Duelunds me meer aan dan de Mundorf SGO's. Ik hoo rhet liefst een beetje relaxed hoog. Geen idee hoe ik dat hier zou moeten omschrijven maar ik heb een hekel aan een in-your-face-tweeter
Mundorf M-Cap Supreme Silver/Gold/Oil 1200VDC – 2% tolerance
Technical specifications (according to manufacturer): "The MCap® SUPREME silver/gold/oil is definitely the top-of-the line model of our oil impregnated capacitors. In comparison with the Silver/Oil version, it technically features a further extended lifetime. More importantly, sonically the Silver/Gold/Oil version stands out due to its wonderful natural singing and exceptional micro dynamic, same time." Capacitance: 0.010uF-10uF; Dielectric: Polyprophylene; Metallisation: 99.99% silver, 1% gold; Purity of silver: min. 99.97% typ. 99.99%; Purity of gold: min. 99.97% typ. 99.99%
Sound: At this level we are talking about a really serious capacitor, so my findings are relative to other exotic types. They are richer and better layered than the Mundorf Silver/Gold, they seem more open and more spatial. Compared to the Duelund VSF copper they are not as well harmonically structured. The Duelund VSF copper capacitor creates smoother harmonics and a better midrange balance. The Silver/Gold/Oil excels in image depth, call it "bowling alley depth"! In direct comparison the Duelund VSF copper sounds flatter. Like the Mundorf Silver/Gold, the Silver/Gold/Oil has a slight top-end emphasis, this probably contributes to the perceived spatiality and micro-detailing. It will depend on the implementation and personal taste, some may prefer the Mundorf Silver/Gold/Oil, some may prefer the Duelund VSF copper foil capacitor.
Verdict: 12
Duelund VSF-Cu Copper Capacitor - 100VDC – 2% tolerance
Technical specifications (according to manufacturer): “The Virtual stack foil capacitor, a capacitor made specially for loudspeaker crossovers. This new capacitor is the realisation of a lifelong ambition. It consists of copper foil and high-density paper, soaked in pure mineral wax, coated with pure cocoon silk and finally, treated with special lacquers made from natural materials. It is without question a "green" product. The actual construction has been overseen by Mr. Steen Duelund Chief Engineer of Duelund Coherent Audio. Mr. Duelund has dictated the capacitor's special characteristics, i.e. its flatness, giving the opportunity to create its stack-foil working manner ensuring very low inductance, forming a solid block resulting in a form free of internal resonance. Furthermore, the flatness makes it easier to achieve greater values by connecting the capacitors in parallel”.
Sound: Now I know how natural a capacitor can sound! They are super natural, smooth, clear, open, and at the same time they stay calm and controlled but delivering dynamics when the music calls for it. The tonal balance is near perfection, especially audible on acoustic instruments and the human voice. This makes my classical music collection so much more realistic. Also I was very pleased with the separation of every individual instrument in an orchestra, the string section is much more a group of individuals rather than just a group. In direct comparison to the Duelund I found the Mundorf Silver/Gold to be a little over-etched sometimes, they seem to have a slight top-end emphasis but this is nit-picking.
Verdict: 12,5
Duelund CAST-Cu Copper / Paper-in-Oil Capacitor - 100VDC – 2% tolerance
Technical specifications (according to manufacturer): “The Duelund CAST Capacitor is a no holds barred flagship capacitor. The construction builds on the foundation of the Virtual Stack Foil design but does so with the addition of a proprietary WPIO dielectricum which necessitates several days of impregnation under high pressure. This creates a form with incredible damping properties giving a mechanical stability hitherto unheard of. On top of this casting process, a ring of hard pressed paper strengthens the damping properties of the design helping music flow effortlessly. The Duelund CAST capacitor is available for speaker use and as the CAST 630v for DC-applications.”.
Sound: The CAST capacitor has all the same characteristics as the VSF but with added top-end clarity and together with that, more spatiality. They are (like the VSF) super natural, smooth, clear and open. The tonal balance is extremely neutral, especially audible with good recordings of acoustic instruments and the human voice, so maily with classical music. Like the VSF the separation of the individual instruments is very good and in an orchestra, the string section is a group of individuals rather than just a group. Soprano's have clarity without becoming hard to the ear, wind instruments (especailly the copper section) have that nice "metal" edge without becoming rough. Where in the past you had to choose between a Mundorf Silver/Gold/Oil (very good depth and imaging) or a Duelund VSF (very neutral presentation) you can now have the best of both worlds in the form of the Duelund CAST-Cu. I did find they needed a couple of weeks use to fully come to bloom, so give a chance to burn-in. My current reference!
Verdict: 14
dusssssssssssssssssssssss.......
Zit ik toch te denken aan de VSF.......dat lijkt mij een hele mooie. Ik heb de G's van Ruud mogen beluisteren en dat hoog beviel mij supergoed.
De VSF condensatoren zijn een stuk prijsgunstiger dan die CASTversie van Duelund.
