Såg i senaste Stereophile att Audioquest kommer med nya kabelmodeller med en typ av aktiv skärm.
Dom verkar inte ha fast dc-matning via batterieliminator som Synergistic Research, utan med en liten plåtmojäng som kallas DBS, fäst vid högtalaränden, som går på eget batteri ( 12V för signalkablage & 24V för ht-kablar ).
Dom nya modellerna på bild heter Mont Blanc (ht) & Cheetah (RCA).
Prisindikationen på signalkablar med DBS är från 300 dollar samt från 400 dollar för ht-kablar (8ft).
Dom fanns dock inte på deras hemsida som tydligen skall uppdateras den 1e Juli.
-Kanske därför Granite, Mammoth & Calderan har gått på "rea" den senaste tiden ?

Jeg har lige pratat med den danske importøren af Audio Quest. Jeg får et signalkabel och et sæt högtalarkabler til test - båda med batteri. MEN ..... dom kommer först til Augusti! .... TÅLAMOD

Hej!
Tänkte jag skulle hoppa in och reda ut begreppen lite...
DBS är inte alls en aktiv skärm a la Synergistic Research, utan någonting helt annat.
DBS (Dialectric Bias System) är en patenterad uppfinning från Audioquest som gör att kabeln är fullt "inspelad" ("charged") direkt ur lådan och förblir så så länge batteriet är inkopplat.
Systemet fungerar på följande sätt: (Efter som jag inte hinner översätta just nu, så kommer den engelska förklaringen. Svensk version kommer efter sommaren på www.ljudtema.se)
-------------------------------------
The patent pending DBS is a simple, elegant solution to one of cable's most vexing performance challenges.
A highly misunderstood area of cable performance is the subject of cable run-in, sometimes (inaccurately) referred to as "break-in." "Break-in" properly applies to one-way mechanical phenomena, such as a motor or a loudspeaker surround. Cables and capacitors do not "break-in", rather their "dielectric forms," meaning that it takes time for the dielectric material to adapt to a charged state.
This process is quite audible and explains the significant improvement heard in electronics, loudspeakers and cables as signal is applied over a period of time. It has long been noted that cables (and all audio components) sound better after having been left turned-on for a number of days. It has also been noted that once turned off, the component or cable slowly returns to its original uncharged state. For many music lovers, this means that they are almost never hearing their cables in their optimum state.
AudioQuest's founder and chief designer, Bill Low, explains the Dielectric-Bias System: "DBS puts all of a cable's dielectric into a comparatively high voltage DC field ... continuously from the time the cable is terminated. The exceptionally simple design uses a wire down the middle of the cable, which is simply an extension of a battery's anode. This wire is attached to positive (+) of a DBS battery pack, and nothing else. It is not in the signal path and has no interaction with the signal. Depending on the model of interconnect (analog or digital) or speaker cable, an existing shield or outer spiral of conductors is used as the DBS cathode by connecting it to negative (-) of the DBS battery pack. The negative side of a battery is nothing; it's just an empty reservoir. Again, there is no interaction with signal flow and no extra connections are introduced into the signal path."
Because there is no "load" on the battery, it will last for years. A test button and LED on the DBS pack allow for easy verification of battery performance.
The benefit of maintaining a bias on the dielectric at a substantially higher voltage than is ever achieved through normal use is dramatic. Even a cable, which has the loudest music or pink noise continually traveling through it, never has a fully formed dielectric.
"If you have ever experienced the significant performance difference between a product when it was new or not used for a couple of weeks, compared to two weeks later ... simply imagine the same improvement doubled or tripled," said Low. "There is no new language for this phenomenon. It is simply more of the same improvement experienced to a lesser extent by leaving one's equipment on continually. I hope when you have the opportunity to experience AudioQuest DBS cables, that your response will be the same as mine when I put the first prototype in my system; "Ahhh, thank you!"

Om det saknas en engelsk förklaring ovan (D v s om den är bortredigerad) så maila till cme@ljudtema.se, så mailar jag en kopia.
Kablar med DBS-systemet finns för demo efter sommaren. |

Granite, Mammoth och Caldera har utgått (men Granite kanske gör comeback...), därför säljer handlarna ut sina demoex. |
