ETI Eichmann Bayonet Plug™
The Bayonet Plug™ is a totally new approach to
speaker cable connection where every aspect of electron
flow has been considered.
The result is a connector that offers better sound quality
for speaker cables in all price ranges - from low-end
What you should know about banana plugs:
Most banana plugs use the conductive element as the
locking system. By doing so, conductive performance
of the connector is often neglected in favour of the
mechanical means of connection.
the following banana plug designs:
split-pin design where the conductor pin is sliced into
2 or 4 elements thereby creating a frictional springing
action to lock within the binding post.
A barrel spring where separate leaf contact portions
are arranged in a cylindrical fashion around the conductive
pin, compressing on entry and frictionally holding the
pin within the binding post.
A single compression type spring (often a stainless
steel wire) that forces a hollow pin against the inside
of the binding post.
A hollow thin-wall tube pin, split down one long side,
that makes frictional contact via the inherent springing
nature of the metal material used i.e. Beryllium Copper.
All the above designs provide a secure connection, but
sound quality can be compromised in a number of key
of the above banana plugs are made from gold plated
Brass or Beryllium Copper with a conductivity rating
of 28% IACS (International Annealed Copper Standard).
As a comparison, the high purity copper used in most
speaker cables has a conductivity rating of at least
of this low conductivity, we believe standard banana
plugs can compromise electron flow.
large cross-section of many Brass banana plugs can also
cause phase errors and smearing due to skin effect -
where high frequency signals traveling on the surface
of the conductor are conveyed faster than low frequency
signals traveling at varying depths and speeds within
the metal itself. The result is often a slow, bass heavy,
contrast, the hollow thin-wall tube pin can be compromised
through a lack of mass - where the wall thickness doesn't
support the large current flow from amplifier to speaker.
The result is often a lightweight, bright sound.
finally, the split pin plug and the barrel spring plug
can induce eddy current distortion where the signal
is conveyed through multiple contact points.
The new Bayonet Plug™ connector solves the problems
of banana plugs and provides a faster, cleaner signal
of high purity and detail.
achieve this we use a conductive pin of ideal thickness
and mass - with minimal skin effect problems, and whose
locking means is via a non-conductive frictional pressure
insert (patent pending) rather than via the conductive
