You have not heard your Loudspeakers potential untill you have heard these Loudspeaker Clarifiers,These come as a pair. Once these are runin the refinement is Very apparent, compared to without them.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 these ,These Copper foil paper in oil capacitors from Poland Are Fantastic-every bit as good as the Jensen’s, and Jupiter Copper foil capacitors and $100 less .resolution,depth tonal accuracy and soundstaging is Excellent by any standards. 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 .
