The new Kryo XLR Connector marks the first time ETI Research has produced this type of connector. It has taken time for CNC machining to progress to the point where the female connection can be machined to the thickness ETI Research knows is best.
For a long time XLR connectors with some type of Copper have been available but many of the male pins have too much mass, which causes excessive capacitance and alters the sound. Some of these XLR connectors had Copper male connectors while the female connectors were still Brass formed! This is because the hollow nature of the female pin was difficult to machine and a lot cheaper to make by using the original pins formed in Brass molds.
ETI Research was still not interested because this defeated the purpose of using Copper for greater sound quality. The next step to produce female connectors out of Copper was undertaken by rolling flat Copper to make the female connection. This resulted in more problems when it came to uniformity because the surface contact area for inserting the Male was not consistent and could make the connection unstable.
Associated with these problems was surface thickness. ETI Research has found the best sounding thickness for low-voltage connectors: Thicker causes negative influences in sound quality, as did going too thin. We feel the best connector has the least effect on sound and that is what ETI Research works to achieve. So we waited until we could manufacture what we felt was the best on the market.
The ETI Research Kryo XLR Connector has both male and female connectors CNC machined with optimum wall thickness and made from Tellurium Copper for durability, which is important for long-term use. The result in the unsurpassed Kryo XLR you see today.
Accommodates cables up to 13mm, or 9mm with insert installed.
