Here is a great example of getting the best money can buy And still a great value. Other companies sell http://www.humblehomemadehifi.com/Cap.html
Clarifiers But not on this level and charge more $$ .These will improve Any Loudspeakers.The Duelund Silver foil paperoil Capacitor Is considered the best capacitor in the World, the capacitors alone are over $200 , the resistors and capacitors are matchedpairs to within 1% tolerance. The Purest wire known is used OCC Copper ,and Gold overCopper Connectors ,not Brass like most connectors are.Spades or Bananas.What this purifiers do is filter all the hash and noise above. 10,000 kHz. You will be very surprised to know most of all AC noise is at thehigh frequency level.you music is noticably more natural These Clarifiers are made to your Loudspeakers impedance Specifications ,all others commercially sold is a one size fits all which is Impossible. Your amplifier sees this Zobel network as a more stable resistive load. Which you will hear a more balanced musical event. Hear the difference .p.s please see my feedback and references on these Clarifiers. See review comments from Humble homemade Hifi capacitor test below
Sound: In one word: amazing! I have used these 0,01uF pure silver foil capacitors as bypass capacitors in many different systems. In just about every case there was an improvement in overall coherency and realism of tone. With realism of tone I mean that acoustic instruments and vocalists seemed much more tangible, more intimate. The Duelund Silver Bypass Capacitor brings out a certain harmonic richness in overtones, for example with brass wind instruments the tone gets a sort of "glow" making them so much more realistic. Big-band music is bright and warm at the same time if you know what I mean, just like in real-life. And now for a cliché: the Duelund Silver Bypass Capacitor really does remove a curtain from the sound, creating more depth, insight and it generally does a very good job in cleaning things up. It does this without getting harsh nor adding artificial emphasis on any part of the spectrum, something that can happen with certain types of bypass caps. They even scared me once: my personal reference system uses a 1-inch beryllium compression driver connected to a tractrix horn that flares out to 29 inches. This "tweeter" has no resistors in the signal-path and is driven by a first order network, so only one capacitor in the direct signal-path. It works like an acoustic magnifying glass. I was fiddeling around as usual, tuning the value of this capacitor in steps of 0,10uF but the sound didn't quite seem to fall into place how I wanted it to. Then I decided to listen if the 0,01uF Duelund Silver Bypass Capacitor could help out here. Bingo! Makiko Hirabayashi's recording "Surely" (that I know very well) has some small bells that are used on several of the tracks. I thought I knew how they sounded but with the bypass capacitor in the network the bells were so realistic, it scared me :-) I am so pleased with these universal bypass capacitors that I have decided to keep them in stock.
