The conductor"s 2.5% silver plating helps improves high frequency performance. Hard cell foam insulation surrounds the conductor to minimize distortion. Foil wrap around the insulation and an additional layer of silver-plated braid shield the cable from external electronic interference that can degrade the signal. 2.5% silver-plated 24-gauge solid copper conductor Accommodates extremely wide bandwidth Low-loss transmission Gold-plated RCA connectors Hard cell foam insulation Foil shield and silver-plated braid shield minimize interference
