Duelund-Path Audio Ultimate Loudspeaker purifiers

I have been building Loudspeaker purifiers for 4 years now . These are priced per matched pair.
Any seasoned Audiophile knows the Duelund name for the best 
and to complement them the hand built Path Audio resistors . Please note the New Mundorf ultra Copper foil resistors are the only Copper foil and most detailed made !. Please check out my feedback from others on these Audio purifiers      ,it’s one upgrade you can hear !  I was asked about competing Commercial brands , There is No comparison in quality with synergistic research xo purifiers for example, their parts are in a little tube. High quality parts like the Duelunds are 3 x bigger and Far better sonicely ,  and built specifically for your speakers , not a one size fits all,which is Impossible, for Loudspeakers have ohms ratings from 12-2 ohm ratings .
these are Custom built to your Loudspeakers ohms rating.impedance curve .
How these work is all your equipment presents noise from magnetic 🧲 
fields from power supplies, transformers switching and many other factors.
which = this to all electronics connected .in the high frequencies is where this is most apparent .Everything  flows down stream to your Loudspeakers ,these purifiers filter all the residual noise . Just connect 
bananas or Spades ,give them some runin time and your top end is smoother ,more refinement,if you stream music even more so, that HF hash is removed .
please see some of my past feedbacks,these are better still.these are Duelunds Tinned Copper foil oiled Waxed paper.Path audio superb quality 
go to Humble homemade hifi capacitor test ,these purifiers have -0 to do with your loudspeakers internal Xover .Everything is filtered Before hand.
please note I can build these with Duelunds Silver foil waxed paper oil capacitors as a option ,.priced per pair.
if you feel you want,need a bit more openness and detail if your speakers are real warm sounding  they are $100: more ,thank you for your consideration
