You have not heard your Loudspeakers potential untill you have heard these Loudspeaker Clarifiers,These come as a pair.once runin hese capacitors are World class.The refinement is Very noticable,please see my feedback and comments on these Clarifiers.Now comes with a system breakin recording and system tuneup on a thumb drive ,just play music without them ,then plug these back in you don’t need to look for the difference it is very aparent. These are the the Best value of all Loudspeaker Clarifiers,1 pair is all you need. I have experimented with the best ofthe best Price no object .These New Milflex capacitors from Poland Copper foil capacitors Are Fantastic-and $100 less and closeto Jensen’s,and Jupiter capacitors,resolution,depth tonal accuracy and soundstaging is Excellent by any standard. To complement them I use The Very accurate Kiwame Resistors ,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 .
