Kabler med batterier ?

[TheDuke]

Forleden så jeg et audioquest kabel der har et batteri tilsluttet    Er der nogen der kan fortælle mig hvad det går ud på ?

Art Dudley skrev en spændende testraport for noget tid siden i stereophile om det. Han kan ikke høre forskel   men syntes det er nogle rigtig gode kabler, også uden batterier.

Ellers skriver de selv...

"DIELECTRIC-BIAS SYSTEM (patent pending): Unfortunately, because insulation stores and releases energy, it is also a “dielectric.” In a cable application, all released energy is distortion. The misnomer “break-in” is often used to describe the pronounced improvement in performance as the dielectric adapts to a charged state as the cable is used. Whenever a cable does not have a charge on it, it is re-adapting to an uncharged state; it is becoming new again.

By maintaining a 36 volt dielectric-bias, far above the voltage of delicate audio signals, the DBS system provides considerably better transparency and dynamics than is possible even from a cable in continuous use. It takes a couple of weeks for the DBS system to reach maximum performance. Since DBS battery packs are attached when Gibraltar cables are first terminated, Gibraltar will be approaching or at peak performance by the time it is installed in your system. Since there is no “load” on the two standard hardware-store batteries, they will last for years. A test button and LED allow for occasional verification of battery performance."

Et rigtig farverigt indlæg fra Dudley. MEN der er par huller. Efter at have prøvet et utal af kabler i endnu flere kombinationer, bliver man hurtig klar over tid er vigtig faktor. Om man er troende eller hvad det er, så sker der noget med et kabel, når det har været monteret nogle dage (eller uger). Om det er stråling fra det ydre rum eller hvad det måtte være, er ligegyldigt, men som Dudley også skriver, kan man tro sine ører.

Har man prøvet nogle af de nye kableltyper fra Audioquest (f.eks. SKY) og Synergistic Research (f.eks. Resolution Reference) er man ikke i tvivl. Der er en forskel. Såvel om de kører "passivt" eller tilkoblet strøm, ligesom (også Audioquest) ter sig anderledes over tid - som det også er tilfældet med almindelige kabler.

Det gyldne råd vil altid være at lade kablerne køre over flere dage - AB test over éen pladeside med fokus på højtone og bas, giver sjældent nogen oplevelse. Hvem sagde noget om dybde-, højde- og perspektiv generelt?

Kom med et par eksempler fra den virkelige verden ...
