Metal Conductivity
The superiority of Silver over other precious metals for audio signal transfer.
Silver
Silver outperforms all other popular metals used for audio signal transfer. If you’re serious about premium-quality sound, you cannot beat Silver audio connectors.
Copper
Copper offers superb conductivity over other metals such as Brass and Titanium. Copper has become the standard against which all other electrical conductors are measured.
Brass
Contrary to popular belief, Brass is not a great conductor of audio, severely outperformed by Silver and Copper. You really can hear the difference in audio quality.
The ETI-Research Difference
ETI-Research products emerge consistently from competitor and class comparisons with a reputation for the best music reproduction. Creation and development of each product takes years of science and engineering. From the traditional to the eccentric, no concept or idea escapes our design and evaluation processes.
Every detail in a system makes a difference. Passionately believing this and knowing that our customers enjoy the benefits of high-performance audio motivates us to maintain our standards and continue pushing beyond the boundaries. When you desire simply the most superb audio quality available, you must demand ETI-Research components.

Design philosophy
In every product design ETI-Research strives for innovation that attains superior audio performance. The basic areas of connector design we evaluate are:
Geometry
At ETI-Research, everything is calculated and engineered to streamline the flow of electrons in beautiful symmetry.
Mass
The optimum mass is targeted to avoid skin effect, but also to ensure the full frequency range is available to be heard.
Materials
Strength, reliability and minimising the EMF effect of the structure on the signal are key attributes of ETI-Research audio connectors.
Metallurgy
ETI-Research does not compromise on quality, exclusively using nothing less than Copper and Silver throughout production.
