The AudioSt SuguRip 300 Multi-Size spade cards guarantee pure and durable contact with their purple copper (purple copper), their direct-silver or direct-gold veneer, and their seamless Cold-Weld process. Set of 4 pieces.

SUREGRIP 300 Spade cards from AudioQuest meet the highest demands of high fidelity. Made of purple copper (purple copper) with a direct-silver or direct-gold plating applied without underlayment, they eliminate signal degrades due to oxidized or lower quality contacts.
The driver in Purple Copper displays an electrical conductivity greater than the current copper alloys, for optimal energy transfer between amplifier and speakers.
The plating is applied directly to the copper, without nickel underlay that induce magnetic distortions. Two variants available: Direct-Silver (high conductivity) and Direct-Gold (maximum resistance to oxidation).
The seamless connection by Cold-Weld creates a molecular junction between the driver and the plug, eliminating the weld points that alter the quality of the signal and degrade with the time.
The multi-size design accepts cables up to 9 AWG. The polyethylene pom isolate clock perfectly connects and facilitates handling. Set of 4 special cards.
