You have not heard your Loudspeakers potential untill you have heard these Loudspeaker Clarifiers,These come as a pair.once runin The refinement is Very noticable ,just play music without them ,then plug these back in you don’t need to look for the difference it is very aparent. Just lookup Humble homemade Hifi capacitor test, these capacitors are one of the top 5 in the world.These are the the Bentley of all Loudspeaker Clarifiers,1 pair is all you need. I have experimented with the best ofthe best Price no object capacitors and these Milflex Copper foil in oil capacitors from Poland are every bit as good as the Jensen’s,and Jupiter and $100 less ,These Copper foil paper in oil Copper body capacitors Are Fantastic,resolution,depth tonal accuracy and soundstaging is Excellent by any standard. To complement them I use The Very accurate Kiwame Resistors from Japan,matched to within 1%,I use Very high purity Copper and Only Goldover High purity Copper Connectors ,unlike most that use inferior Brass I only use Copper . You just plug these into your binding post spades or Bananas , give them at least 50 hours to start opening up .Compared to the much more expensive SR Clarifiers I had and Sold, Not in the same league . These will make Any Loudspeaker sound better and your amplifier runs more efficiently seeing a constant Resistive load and operate more efficiently.I build these one at a time exactly to your Loudspeakers Specifications ,ohms ,and impedance curve ,not a one size fits all. I spent several months testing and installing these on Electrostats,planers and , conventional monitors and towers from $1500to well as over $30k Speakers without exception .
