Re: [regsaudioforum] RE: DNM Wires
- Going by what is on the website the use of low metal content is not supported by arguments
except for a reference to eddy currents. My understanding is that these are circular electrical
currents that flow when a conductor cuts a magnetic field. They can be useful and also
troublesome in various sorts of electrical machines where the current or magnetic field is
substantial. The use of metal for shielding in connectors and cases is well established. The
magnetic fields and currents in the vicinity of hifi equipment are small, too small for eddy
currents to be a problem. It is not clear how or why an eddy current in a case, shield or
terminal is a source of audio problems and DNM offer no explanation.
Regarding the electronics there is no price list so it is not possible to compare with similar
offerings. The approach seems to be to tell us there is something wrong with our existing
equipment, and the problem is due to magnetic fields and feedback loops that cause loss of
emotional involvement with recorded music. There are nightmare tales of stuff going on that
apparently has never been investigated or mastered by anyone else in the 90 year history of
audio. The solutions apparently are available only to DNM customers. There is a brief
specification page, mostly without limits or tolerances. There are no charts or measurements
to support the claims. I'm skeptical.

- What is known about components added at either end of these cables?Fred.

what do you mean by RC-filter?
Speaker cables have a timeconstant T=L/R and the DNM comes close to 10 which is pretty good.
