My sisters husband is a psychologist and he mentioned both the Asch conformity experiment from the 1950's (wiki it) and the phenomenon that happens when something is repeated so often that it becomes fact whether it is true or not. With what is known as the scientific method. I'm not the one asking for it, the op did, I'm just showing it. The Black Gate was very affordable when comparing it to some other similar-performing capacitors, and was easily available.Once again if you didn't get it before (or actually read it in its entirety). Once the capacitors will become unavailable, or the current stocks become too old to be used due to deterioration, alternatives will have to be found. which should close its doors in August 2007, once all their stocks get sold out.
#AUDIO SIGNAL PATH CAPACITORS LICENSE#
The capacitors were manufactured by Rubycon under license for Jelmax Co., Ltd. and Rubycon Corp., after 18 years of availability. The Black Gate production has stopped in 2006, said to be caused by problems between Jelmax Co., Ltd. This settling period or burn in period was most likely attributed to the aluminum layer completing its reaction to form a complete and stable oxide layer on its surface once current and voltage are applied to the capacitor in a circuit. Once completely 'burnt-in' however, the benefits are said to be heard clearly. This long settling-in procedure is often a controversial issue when auditioning such equipment, as the frequency response is said to tend to shift around greatly during this period, making the equipment sound different from one audition to another. Many audiophiles believe it can take many hours before the maximum sonic benefits are heard in audio circuits that use Black Gates. Since aluminum oxide has the characteristics well suited for its dielectric duty to insulate the cathode from the anode whilst permitting a relatively high flux environment as the oxide layer formed could be very thin allowing the plates to be very close to each other, thus increasing capacitance. While the manufacturer may claim that graphite (graphite is a conductor not insulator) is used as the dielectric in its capacitors, the truth is the carbon impregnated paper inside the Black Gate capacitors was the cathode, the aluminum foil was the anode and the alumina (aluminum oxide) layer that formed on the surface of the aluminum anode was the dielectric (separator) between the two plates. The manufacturer attributes the capacitor's sonic quality to the use of fine graphite particles used in the separator between its anode and cathode. Many of their capacitors on the market are now fakes or just not available.īlack Gate capacitors base their manufacture on something called 'The Transcendent Electron Transfer' theory.
They do however, continue to be held in high regard by many high-end Hi-Fi manufacturers ĭue to dwindling stock and demand, prices have skyrocketed lately. The Black Gate capacitors are considered by some (Audio Note among others) to be the best electrolytic capacitor ever made although they are now discontinued.
They are also known to deteriorate (or "drift") over time, just like any electrolytic capacitor. The quality of capacitors may vary considerably depending on their construction and the type of insulating materials used. They have acquired a reputation for very high quality for use in the signal path, and power supplies, of audio circuitry.
