Duelund-Mundorf Ultra Loudspeaker Purifiers -Quality you can Hear !!

These are Very new to the market but already starting to get   excellent feedback. How these Purifiers work , Every piece of electronics you own creates noise , These clean the Audio signal Before it reaches the Xover inside your Speakers ! These work with Any  type of Loudspeakers ,Big or small, Electrostatic or planer, with DSP, or powered Bass. The noise that rides in the High frequencies applies to All electronics with No exceptions ,once you hear your system after  breakin you get a more defined Musical  presentation .  priced per pair. - Sale pricing.

These filter noise that rides in the musical signal Before it enters your Loudspeaker,  and with No possible negative effects in any way .

Transformers,power supplies switching which create magnetic 🧲 fields 

X this combined ,and this goes down stream to your Loudspeaker 

ThesePurifiers Eliminate  High Frequency noise that is there , like your AC line filter, these regenerate a Clean signal before it enters Your Loudspeakers .  

Once removed you hear a clearer musical performance. The key is using the 

Best parts made this filters this and are far superior to your Loudspeakers Xover parts,the wires  are -0 Crystal Copper and Gold plated Copper connectors not brass like most mfg. for better Sonic purity.

Parts internally ,once runin , it’s very apparent . You just plug these into your speakers and they do the rest.

Duelunds  New state of the art facility -see Pictures below.These are now more reasonably priced version of their top Cast capacitors,these Are a pure Copperfoil, not metalized poly caps sprayed on plastic like most.To complement them the Mundorf Ultra Copper foil resistors are the most Accurate available .    Just plug these in Banana, or Spades .

technical data below   

                      By using the Best of the Best and custom made to your Loudspeakers ohm,and impedance specifications. From - Duelund - they are constructed with Wax paper in Oil dielectricum, previously reserved for their top of the line CAST series. The paper separating the copper foils are vacuum impregnated in a deep vacuum 100 times lower than what was possible at the old factory. Following this, the windings are also wax impregnated to help seal the winding completely. This formula makes an incredibly robust high performing capacitor at an amazing price considering they are constructed from the

finest Copper foil. Please see. humble homemade Hifi capacitor test, These  Duelunds capacitors are special.

Vs Stein ,or Synergistic OX clarifiers when compared -Not in the same League in quality, Refinement or musicality, and Duelunds are less $$ !!



The development of Mundorf's M-Resist Ultra Resistor is based upon the well-known transparent tonal properties of Copper - Manganin foil. Compared to all wound-wire resistors, this film provides a huge reduction in inductance. Copper is significantly softer than the metal-oxide used for metal oxide, MOX resistors. The Natural resonances of the copper-manganin foil are therefore significantly less pronounced, which means that distortions caused by crystallurgy and electroacoustics are significantly reduced. These are for those who demand the best. Our other model the Milflex are still very good and $100 less,Thank you.
