Jag säljer ett par signalkablar av typen Audioquest Jaguar XLR.
De är 2m långa, och nypriset ligger på 3300:-.
Mitt pris 2000:-
Eventuellt byte med nåt annat kul, typ vad som helst kan vara intressant.
Dielectric-Bias System (DBS)
Batteries on a Cable? The world of audio/video cables has long been famous for hype and mystique ... and for sometimes profound and important variations in performance. Into this clutter of both reason and irrationality, AudioQuest introduces an astonishingly simple solution to a universally acknowledged problem.
From the occasional "flat earth" engineer to listen-in-the-dark music enthusiasts, the effect of insulation on performance is universally acknowledged. The technical term "dielectric" exists because no insulation (other than a vacuum) is perfect. All insulation is a dielectric when in the presence of an electric field. The difference between an ideal perfect insulator and a dielectric is distortion and loss.
The grossest errors caused by "dielectric involvement" are caused when the dielectric has not been given sufficient time and voltage to stabilize. The incorrect term "break-in" is often used to describe why electronics and cables need to be turned on continuously for two weeks before reaching maximum performance. "Break-in" properly applies to 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.
AudioQuest's patent pending 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 puts a wire down the middle of the cable which is simply an extension of a battery's anode. This wire is attached to positive (+) at the DBS battery pack, and not to anything 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 (-) at the DBS battery pack. In some models there is no preexisting outer conductive layer, so a shield-like conductor is added solely for use as the ground plane of the DBS system. For all the models which have dual purpose outer conductors, it is mere coincidence and cost saving that these conductors are able to serve simultaneously as DBS cathode, and in their normal function as shield or negative conductors. 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 to the signal path. The battery(s) are doing no work and last as long as the ones on a storage shelf, though the DBS pack includes a button and LED so that one can confirm battery status.
The benefit of maintaining a bias on the dielectric at a substantially higher voltage than is possible through normal use is dramatic. Even a cable which has the loudest music or pink noise continually traveling through it never has 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.
There is no new language to this phenomenon. It is simply more of the same language as any other straightforward improvement. DBS is incredibly simple ... incredibly effective.
