These Loudspeaker Clarifiers use only the best Copper Wire as well as Gold overhigh purity Copper not brass http://www.humblehomemadehifi.com/Cap.html
connectors and matched resistors and capacitors.Nor comes with a system breakin recording ,and system tuneup on a thumb drive. these Clarifiers remove high frequency grunge and noise that allways rides in the above 10 kHz range ,your amplifier to will. run more efficiently .please see my feedback and this exceptional Review of these top tier precision made capacitors from Poland .they exceeded my expectations ,and on special $50 off regular price and Free shipping . Milflex Copper paper poly,oil capacitor.review humble homemade Hifi.- I have Very limited supply North America is Sold out in the values I useuntil June. They are that good !! Duelund May be the only capacitor better ,depending too on your amplifier.
Verdict: 13+ Vs your average Solen capacitor in Many Loudspeaker that are rated a 6 for example.
Please see my feedback,and comments on these Clarifiers.
Sonic craft - review on the Milflex Copper foil- oil capacitor
This Copper foil, Paper/Polypropylene/Oil cap yields the most natural sound I have heard to date. This cap differs from other caps in that it is not application specific. Instead of focused improvement in one place or another, it is just purely musical across the range. Warmer and richer than any plastic cap. Not "just darker" like some cheap oil filled.... or polyester... Detail and transparency that is real, not pseudo qualities like those found in so many caps today. No "two steps forward, and one back" here. Check the dimensions because these caps are not small. The leads are twisted pairs of 22ga solid Copper. This twisted pair would require a through hole (via) larger than 0.046" (1.17mm). Short lead is on the "stripe side" which indicates shield, and exceeds 2" in length. Tolerance is better than 5%, Dissipation Factor is better than 0.0035% at 1kHz. 600VDC Dimensions: 0.715" diameter by 1.575" in length.
