The ETI Cable Pod contact element is optimised for sonic performance which offers vastly improved signal transfer, enhanced sonic performance, and a faster, more direct connection.
The large mass of metal used in many binding posts, while visually impressive, has also been shown to introduce phase errors and smearing due to skin effect – where high frequency signals travelling on the surface of the conductor are conveyed faster than low frequency signals travelling at varying depths and speeds within the metal itself. The result is quite frequently a reduction in time domain linearity and compromised sonic performance, manifesting itself as slow, bass heavy, smeared sound.
The ETI CablePod contact element is ideal in size and shape to support current ﬂow but to minimise skin effect, which makes it optimised for sonic performance
In summary the ETI CablePod™ is a totally new approach to multi-way binding post connection. Its innovations and reﬁnements include:
- creating the optimum shape, mass and thickness of the conductive element to enhance electron ﬂow
- incorporating high conductive materials such as tellurium copper or pure silver in the construction
- attention to the mechanical aspects of the design to ensure the ultimate connection of any spade, banana plug or bare wire connection
- removal of the securing nut from the conductive pathway
|Standard binding posts||CablePod™ (tellurium copper)|
|Gold plated brass or phosphor bronze with a conductivity rating of often less than 28% IACS (International Annealed Copper Standard).||A contact element machined from high-purity tellurium copper (over 90% IACS) for excellent conductivity. Provides up to 320% greater conductivity than gold plated brass binding posts.|
|Large mass of metal can introduce phase errors and smearing due to skin effect – where high frequency signals travelling on the surface of the conductor are conveyed faster than low frequency signals travelling at varying depths and speeds within the metal itself. The result is often a slow, bass heavy, smeared sound.||A contact element of ideal thickness and mass – to support current ﬂow and to minimise skin effect problems. The result is a clean, open sound with improved detail.|
|Heavy plating of gold over a nickel substrate. This is often a cause of poor sound quality as electrons ﬂow through 3 dissimilar metals with differing electrical and conductive properties.||Direct 24k gold plating (no nickel substrate) to prevent oxidation – and not to inﬂuence sound quality.|
|Secured to speaker or ampliﬁer panels with a brass or steel nut that has a detrimental effect on electron ﬂow.||A high strength polymer moulded thread that insulates the conductive element from the securing nut.|
