Why would anyone use coax cable?
@mikhailark above in this thread I noted that USB is not an option with current streamer/server as I am using the only USB connection on the Node N130 for my SSD with my ripped and downloaded files. My Chord Qutest DAC has pretty good jitter rejection, and for me in my system, a good coax cable sounds better than USB or toslink. I should also note that I have replaced the internal switching power supply on the Node with an external supply from Teddy Pardo, and that made a noticeable difference in sound quality in my system. Whether that was because of an improvement in clock performance and reduced jitter in the coax signal I can’t say. YMMV.
Taking your perhaps rhetorical question more broadly - Google AI says this (with my added comments in italics):
“Some audiophiles believe that coaxial digital cables can offer certain advantages in music reproduction, despite the rise of other digital interfaces like USB and optical:
* Simplicity: Coaxial cables are relatively simple in design, typically consisting of a center conductor surrounded by a shield. This simplicity can make them less prone to jitter (timing errors in the digital signal) compared to some more complex interfaces. (And specifically, coax cables do not carry power, nor do they rely on devices to convert back and forth from optical to electrical signals.)
* Wide Availability: Coaxial cables are readily available and often more affordable than high-end USB or optical cables.
* Proven Technology: Coaxial technology has been around for a long time and is well-understood. Many audiophiles are familiar with the characteristics of coaxial cables and how to optimize their performance.
However, it's important to note:
* Jitter is not the only factor: While jitter is crucial, other factors like signal integrity and noise rejection also play a significant role in digital audio quality.
* "Audiophile" cables: Many high-end coaxial cables are marketed with extravagant claims about improved sound quality. However, in blind tests, it's often difficult for listeners to consistently distinguish between high-quality and more affordable coaxial cables. (Not my experience, but YMMV. If this is your understanding, you probably picked the wrong thread. I suggest you spend more time reading here: Audio Science Review (ASR) Forum.)
* Alternatives: USB and optical interfaces offer their own advantages, such as higher bandwidth and potentially better noise immunity in some situations.
In conclusion:
While coaxial digital cables remain a viable option for music reproduction, their perceived advantages are often subjective and may not always translate into significant audible differences in real-world listening scenarios. Ultimately, the best choice depends on factors like system compatibility, budget, and personal preference.
