The ETI-Research BP-20C Binding Post is a superb high-performance Binding Post available at an entry-level price. Made from 1100 Series Hardened Copper with an IAC Rating of 102%. You can rest assured the audio signal is not being degraded by having to go through a poorly conductive material such as Brass. Copper is far superior to Brass in terms of conductivity and as such the BP-20C offers a level of audio signal quality unsurpassed in similarly priced competitor products. If you want a binding post representing outstanding value for money, this is it.
The ETI-Research Kryo Binding Post is made from Tellurium Copper and Silver Plated for not only superior conductivity but long-lasting durability.
Special attention has been made to wall thickness that enough mass to allow the current demands necessary for many speaker designs. But we have also taken enough unneeded mass away to allow minimum capacitance and resistance.
We firmly believe that this if the finest Binding Post you can buy and are very proud of what can be achieved when using it in a quality system.
The housing is made from Brass for superior vibration damping and high EMI/RF noise rejection. As a final touch to improve wear and corrosion resistance, Cryogenic treatment in the USA to a specific formula is then applied to each connector.
Due to the unique design which unlike most Binding Pots on the market only needs finger pressure to hold a Spade in place. No more having to apply excessive force in hoping that the Spade does not fall out
This combination of high-quality materials and specialised cryogenic treatment all adds up to a superior range of audio connectors designed for use by amplifier and speaker manufacturers to provide superior speaker terminals on their products. 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.
- Cryogenic treatment in the USA to a specific formula.
Do to the unique design of the Kryo Binding Post that only finger pressure is needed to hold a Spade tight without it dropping out which is so common in most binding posts.
The ETI-Research BP-50C Binding Post is a very high-performance Binding Post at an entry-level price. Made from 1100 series Hardened Copper with an IAC Rating of 102% you can be assured the audio signal is not being degraded having to go through a poorly conductive material such as Brass.
ETI-Research has spent countless hours developing and fine-tuning the BP-50C to ensure audio quality does not suffer in any way as it passes through the connector. With exceptionally high quality-assurance standards at an affordable price and the availability to be ordered in bulk, the BP-50C is the perfect high-quality loudspeaker Binding Post as it has a length of 50mm
The Post length is 20mm which is the preferred length for Speaker Back Plates.
The Housing is made with a Aluminum over a Polymer compound. The Polymer threads onto the Post as to not have any conductive material touching the Pure Copper. The Aluminum is great at rejecting EM/RF noise that is so prevalent now days.
The BP-20C has a Gold Plating applied without any nickel. Many manufacturers use a nickel surface applied before the Gold Plating as this makes the Gold have a shiny look. The unfortunate problem is that Nickel is a poor conductor and will degrade the Audio Signal!
Also your choice of securing the wire by either the screw or solder.
The Nut used to secure the BP20C is made from a high-density nonconductive Polymer so that no conductive material is touching the Copper Post except for what is needed to transfer the Audio signal.
