What it Means:
* Oxygen is a contaminant: Oxygen in copper can degrade its conductivity.
* "Oxygen-free" is not 100%: It's highly unlikely any copper is 100% oxygen-free. Even the most pure copper will have some trace amounts of oxygen.
* "Oxygen-free" is a marketing tool: "Oxygen-free" copper is a way to emphasize the purity of the copper used in the cable.
Does it Matter?
* It's not about the oxygen: The main benefit of "oxygen-free" copper is its higher purity, which leads to better conductivity.
* Small differences: The difference in conductivity between standard copper and "oxygen-free" copper is small, and likely not noticeable in most audio setups.
* Other factors: The design and construction of the cable itself, shielding, and the overall audio system play a much larger role in sound quality.
In Conclusion:
While "oxygen-free" copper might sound impressive, it's not a magical ingredient for better sound. The benefits are real, but they are generally subtle. Look for cables that are well-constructed, use high-quality materials, and are designed for your specific system.
Remember: Don't be fooled by marketing claims. Focus on the overall build quality and technical aspects of the cable, rather than just the purity of the copper.
