Description: Beware of low cost counterfeits, your audio and vinyl listening experience will suffer. Unlike a competing cart sled manufactured in China and sold for $14.95, the Best Audio TK24 is 100% American made, and unlike a cart sled manufactured in China, the USA made TK24 features an exclusive gold plated spring inside the gold plated signal pins. Counterfeit sleds have a brass spring inside the signal pin ... a sound killer. Why is a gold plated internal spring the best? It's the science of electrical conductivity, and the pureness of the audio signal as it travels from the stylus to your ears. Below are metals ranked in terms of their conductivity of electrons, and relative to the most widely used metal, which is of course, copper. Silver - 105% conductivityCopper - 100% conductivityGold - 70% conductivity - Best Audio uses a gold plated internal spring on the signal pinAluminum - 61% conductivity - Dual used an aluminum spring pin in the original productBrass - 28% conductivity - Chinese manufactured sleds/pins (and resold in the USA and Europe thru eBay) use a brass spring As you can see, brass is the worst material on the conductivity list, and is why you never will find brass in audio cables. A cartridge sled with an internal brass spring defeats the purpose of any gold plating because the signal is degraded along the path of the pin. At a minimum, the original Dual aluminum pins were twice as pure as brass loaded pins. Our sled is of a higher conductivity that the original Dual sled, and more than twice the purity of a counterfeit. Best Audio uses only gold plated internal springs on our signal pins. As our company logo says, "Hear the Quality". In a blind test we sent our cartridge sleds, as well as some counterfeits, to audiophiles. The results were clear: Brass is the worst sound conductor. Knowing that the metals are critical to audio quality, here are our specs: The Best Audio sled used gold plated pins with interior gold plated springs. The spring is plated with 10 micro inches of gold (per ASTM 488, Type 1, Code C) over nickel. Other sellers cannot quote this spec. In short, lower quality and often non-American made pins use brass internal springs (a sound killer) and display overall worse electrical and mechanical performance and reliability.
