This combination of high-quality materials and precision manufacturing adds up to the highest standard of audio connectors designed for use by manufacturers to enhance the range of speaker cables they can offer their customers. For added versatility, the Kryo Spade Connector gives you the choice of two different size Brass housings to better fit a wider variety of speaker cables. When it comes to producing the best quality audio connectors on the market, ETI Research is leading the way.

The ETI Research Kryo Spade Connector’s innovations and refinements include:

  • Major components made from Tellurium Copper with Silver plating for superior conductivity and long-lasting durability
  • Excellent current transfer due to thickness of the Copper connector
  • Housings made from Brass for superior vibration damping and high EMI/RF noise rejection

Kryo Banana Connector

The ETI Research Kryo Banana connector uses the same high quality materials as the Kryo Spade: Silver plated tellurium Copper connectors for maximum signal transfer and brass housing for noise rejection.

ETI Research Kryo Banana Connector

Perfect for high-end audio equipment consumers expect nothing but the best. If you’re developing a quality audio system for demanding audiophiles, be sure to make the smart choice and insist on ETI Research components. The ETI Research Kryo Banana Connector has the option to use two different sizes of brass housing. This gives you the ability to choose which size housing is suited for your cable. Both sizes are included in the retail box.

The ETI Research Kryo Banana Connector’s innovations and refinements include:

  • Major components made from Tellurium Copper with Silver plating with no Nickel for superior conductivity and long-lasting tarnish-free durability.
  • The Copper connector is lathed from one piece of Copper, with as much material removed as possible to allow for minimal resistance and capacitance, yet retaining the ability to transfer the current needed.
  • Housings made from Brass for superior vibration damping and high EMI/RF noise rejection.
  • Your choice of two housing sizes to suit a variety of audio cables.

Kryo XLR Connector

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.

ETI Research Kryo XLR Connector

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 Connector you see today.

The ETI Research Kryo XLR Connector refinements include:

  • Copper machined connectors, both male and female
  • Silver plated without any Nickel
  • Teflon dielectric
  • Brass housing for superior vibration damping and EMI/RF noise rejection.
  • Short housing to help the XLR cable not extend too much for better cable management

 

Accommodates cables up to 13mm, or 9mm with insert installed.

Kryo RCA Connectors

The combination of high-quality materials and precision manufacturing add up to a superior RCA connector, to enhance any audio cable range by allowing the signal to pass through with minimum alteration.

ETI Research Kryo RCA Connector

ETI Research Kryo RCA Connectors utilise the same design as the Brio range of RCA connectors, but with Silver Plating instead of Rhodium. A Tellurium Copper and Silver combination is a hallmark of the entire Kryo line, as is of course a stringent cryogenic treatment process to ensure absolute quality and material strength over time.

ETI Research employs the Silver Plating process as Silver’s electrical resistance is lower than Copper; more so at higher frequencies due to the skin effect. And of course, when properly implemented, it’s difficult to find a superior method for audio throughput than Silver Plating of Tellurium Copper.

The ETI Research Kryo RCA Connector’s innovations and refinements include:

  • Major components made from Tellurium Copper with Silver Plating for superior conductivity and long-lasting durability.
  • Housings made from Brass for superior vibration damping and high EMI/RF noise rejection.

Kryo Binding Posts

The ETI Research Kryo Binding Post is like no other on the market today. The conductor is made from Silver Plated Tellurium Copper for not only superior conductivity but long-lasting durability.

ETI Research Kryo Binding Post

Special attention has been made to wall thickness to allow enough mass for the high current demands necessary in many speaker designs. We have also taken enough unneeded mass away to allow minimum capacitance and resistance. We firmly believe that this is the finest Binding Post you can buy.

The housing is made from Brass for superior vibration damping and high EMI/RF noise rejection. Due to the unique design, and unlike most Binding Posts on the market, you only need finger pressure to hold a Spade in place. No more having to apply excessive force in the hope that the Spade does not fall out!

This combination of high-quality materials and precision manufacturing all adds up to a superior range of audio connectors designed for use by amplifier and speaker manufacturers. The Kryo Binding Post sets the gold standard for vibration damping and noise rejection while providing outstanding conductivity and flawless performance year after year.

The ETI Research Kryo Binding Post’s innovations and refinements include:

  • Major components made from Tellurium Copper with Silver plating for superior conductivity and long lasting durability.
  • The Copper Body is lathed from piece and hollow to keep Capacitance, Inductance and Resistance to a minimum
  • Superior Bare Wire connection do to a concave connection area
  • Polymer Assembly that not only separates the Brass Housing from the Copper Connector but insures extra tightening capability with Spade Connection
  • Housings made from Brass for superior vibration damping and high EMI/RF noise rejection.

 

Due to the unique design of the Kryo Binding Post, only finger pressure is needed to hold a Spade tight without it dropping out which is so common in most binding posts.
