The ETI Kryo cable boot is the alternative to the ETI Kryo Banana plug for the best possible cable connection from the amplifier to the loudspeaker - even for very high currents. The cable shoe is worked directly from a piece of tellurium copper and then directly silvered for best conductivity and longevity. The cryo-cold treatment with an optimized temperature curve provides a further clear sound improvement. The loudspeaker cable is connected and secured with two screws electrically and mechanically. Included are two brass sleeves of different sizes - each suitable for the loudspeaker cables used. The combination of the best contact material and cryo treatment lead to a perfect cable connection of the highest sound quality.
