Amplifier-End Connector: Multi-Spade, Banana, U-Spade, or V-Spade 

Often, the choice between terminating your speaker cables with spade lugs or banana plugs will come down to personal preference. However, the EU-compliant isolated binding posts used on some power amplifiers often makes it difficult if not impossible to tighten spade lugs with high torque or pressure. In these applications, the AudioQuest banana connector is the superior choice, and may be the only choice.

AudioQuest has conducted a fairly extensive survey of contemporary amplifier manufacturers to determine whether spades or bananas will be most appropriate for a given brand and model of amplifier. Please contact us, provide the brand and model of the amplifier, and we’ll respond with the optimal connector type.

Speaker-End Connector: Spade or Banana

Here we typically recommend the U-Spade or banana connector. However, even though there is less weight and pressure on this side of the cable (particularly for BiWire sets), it is nevertheless important to note the binding post’s design. If a banana connector cannot seat all the way into the binding post, we recommend one of our spade connectors.
