Do expensive optical cables make a difference in sound quality?
The question of whether expensive optical cables make a difference in sound quality is a topic of ongoing debate. Some audiophiles claim that high-end optical cables can improve the sound quality by reducing jitter and other forms of signal degradation. However, there is limited scientific evidence to support this claim, and many experts argue that the difference is negligible. In fact, the digital signal transmitted through an optical cable is either correct or incorrect, with no intermediate states. As a result, the quality of the cable is unlikely to affect the sound quality, as long as the signal is transmitted reliably.
In practice, the sound quality is more likely to be affected by other factors, such as the quality of the source material, the capabilities of the devices, and the settings used. For example, using a high-quality digital-to-analog converter (DAC) or a device with a built-in DAC can make a significant difference in sound quality. Similarly, adjusting the settings, such as the sampling rate and bit depth, can also impact the sound quality. Therefore, while expensive optical cables may provide a sense of assurance, they are unlikely to be the most critical factor in determining the sound quality. A more cost-effective approach may be to focus on optimizing the system settings and using high-quality devices.
What are the key factors that determine the cost of optical cables?
