- A leap in quality for audio connectors
For numerous years, enthusiasts of outstanding sound
quality have been enjoying the nextgen™ connectors
of WBT. With their sophisticated signal conductors made
of pure copper or fine silver in combination with innovative
functional materials, the nextgen™ series offers
everything the audiophile heart desires. By optimising
the mass of the signal conductor, WBT managed to minimise
mass storage effects and eddy currents. The sound is
clearer, and notably more substantial and spatial.
However, WBT goes even further. The think tank of WBT
has been working tirelessly for some years. According
to the principle that the best is still not good enough,
WBT is seeking to improve the nextgen™ principle
even more. This endeavour often seemed very difficult.
The in-house production facilities in Essen had to be
restructured. A PVD plasma production line had to be
established. Already during the construction phase,
dedicated production processes particularly designed
for WBT were developed and implemented on a newly established
However, what does PVD plasma production mean?
have to be protected against corrosion. Around the world,
this is done for connectors almost exclusively by using
electroplating technology. WBT is the first manufacturer
of connectors replacing electroplating by the much more
precise PVD technology. The innovative nanotechnology
replaces the obsolate electroplating technology. For
this process, the signal conductors made of pure copper
are cleaned in a high current polishing line and the
surface is polished to a high glossy finish. This is
done completely without any harmful chemical additives.
The resulting surface is absolutely pure without any
imperfections like chemical inclusions. Afterwards,
the conductor is subject to physical vapour deposition
(PVD) for a physical fine gold plating. In this process,
atomic gold is released by plasma discharge ignition
in a high vacuum. In the vacuum, this gold is literally
shot on the copper conductor to realise atomic bonding*
for inseperably anchoring (*Van der Waals forces). The
result is a homogeneous material compound with a 24-carat
The choice of plasma can be easily explained. With their
nextgen™ principle, WBT had already initiated
a transition to environmentally friendly technologies.
The replacement from galvanic surface coating to PVD
plasma is just the consequent continuation of this basic
thought. In contrast to environmentally harmful electroplating,
plasma technology does not require any toxic electroplating
baths and is environmentally neutral. Additionally,
the new procedure enables reduction of the energy consumption
by approx. 25 %. And resource-saving use of precious
metals can also be ensured.
are the consequences for the sound?
atomically bounded gold ensures a hard and still flexible
surfaces with resistance against scratches and abrasion.
Even more important is the structure in the material
itself. Thanks to PVD plasma technology, a defined crystalline
structure is generated. As electricity is direction-dependent,
this structure enables even further increase in precision
of the signal flow for unparalleled signal quality.
While nextgen™ connectors have improved sound
quality by increased clarity, substance and spatiality,
WBT-PlasmaProtect™ offers even more defined sound.
While wishing an orchestra is playing in the living
room at home, this technology now offers the sensation
of being at the centre of the orchestra. When closing
the eyes, it sounds like standing between the strings
or brass section – and suddenly next to the kettledrum.
One is left with the impression of not only being a
listener but a part of the orchestra itself. With WBT-PlasmaProtect™,
WBT managed to realise a leap in quality for audio connectors.
patented nextgen principle
has taken the design of the RCA connection one step
further with the introduction of the "nextgen"
WBT's nextgen plug and socket offer the following 'on
the top' features:
- ultra rapid signal transfer
- no more interferences (especially Eddy current)
- to perform as a true wide band connector (for digital
- to be the first true RCA type connector of 75 ohms
characteristic impedance offered to the Audio industry
(the perfect solution for digital!).
current exclusion as well as the 75 ohms setting are
impossible to obtain with a standard RCA construction
where the center pin (plus) is built as a massive part
and the outer contact (minus) is also massive and furthermore
formed out of the plug's metal body. Logically, the
nextgen plugs would have to break with today's most
essential RCA design habits. But it was worthwhile!
the nextgen plug and socket feature a characteristic
impedance of 75 ohms, a long awaited piece for all matched
digital audio connections. Now you have the chance to
get the necessary total match of 75 ohms on your system
! You can't do better than exchanging your (standard)
RCA type plug of your digital entries against nextgen
nextgen RCA type plug
core of the nextgen plug design is the central contact
unit built from the plus and the minus conductor piece
and their respective surrounding plastic holders. The
conductors' daintiness insure the properties and performances
mentioned before. Intelligently designed, the whole
unit can be taken off for more comfortable soldering
and clipped back into the central body easily.
All material used is whether pure copper or fine silver
(conductor elements) or highest grade materials like
Ultramid and magnesium for their strength and Dyneon
for its remarkably high heat resistance.
course, the nextgen plug also offers the widely known
'classics' of a WBT RCA:
the patented clamping device effected by the two-piece
outer sleeve (this time working on the thoroughly designed
three teeth construction of the outer contact elements)
- the perfect cable strain relief by means of WBT's
classic Torx screw
is proud to present now their next generation of RCA
type connections based on the 'reduced but pure' principle.
The nextgen RCA socket features a fabulous wave-formed
outer contact embracing the socket's solid Ultramid
It perfectly corresponds to the double prism inner contact,
both conductors then made of highly ductile pure copper
or fine silver. The intelligent wave form insures that
a reliable contact is made any time with any standard
RCA type plug and, of course, with the new nextgen WBT
RCA connector. A perfect solution for digital entries
due to its true 75 Ohm characteristic impedance!
