Charles - you have a wonderful system that gives you great pleasure. You’ve found that solid silver gives you great synergy with the components you have carefully selected. Enjoy it in good health!
Tom

I am fascinated as to how the cable can transmit software code bit perfect regardless of cable used...yet for some reason with audio, there is a huge failure rate on data. How does the cable know if data bits or audio bits are being transmitted? Sorry for a bit of the snark, but when I was at an audio show, those claiming to hear the difference suddenly lost the ability under testing conditions. Why are software transmissions perfect, yet the data data from a FLAC suddenly falling apart?

When transmitting computer data only the recovered 'digital' data is of meaning, but with audio signals the timing of the data is also of significance. The digital clock signal is embedded in the timing of those transitions, and can be directly affected and corrupted by the types of distortion mentioned above. So a digital cable transmitting an audio signal via the SPDIF standard will have the resultant analog signal altered from the original analog signal after D to A conversion from such timing related distortions directly impacting accurate recovery of the digital signal's clock. That's the best I can do to explain the difference between computer data transmission and digital audio transmission and why there is a difference. Hope it helps! |

Ethernet and USB cables are also subject to a lack of galvanic isolation, EM, RFI radiation, induction from EM radiation from wide-bandwidth processors, e.g. CPUs, GPUs, vibration, and other sources of noise. Key parameters here are not only the timing of the signals, but the quality of the power supplies as well. And these noise components are discernable and audible. A big source of garbage noise are the very cheap switch-mode power supplies in computers used as music servers; these are incredibly "dirty". One of the best things can do is to get a computer out of the audio rack and as far away as possible from the amplfication components (inverse-square law and all that...) There is a really good video on this on Hans Beekhuzen's YT channel: https://youtu.be/n26CMGX_yrk

This discussion could be very interesting if BOTH participants had tried both cables in their system.
One is speaking from experience, the other from specs. It would really be interesting if Charles would try out the Venom USB in his system. Maybe he will be surprised. Maybe not. As long as he won’t try it, his arguments reads more like a defends mechanisme than an actual argument from experience. |

Thanks Audio Bill. That is one of the best summaries that answered my question. Much appreciated!

Of note on USB transmission - there are several basic formats. So called 'isochronous' - meaning equal time intervals - is used very often for audio streaming. Unlike formats used for pure data transmission ('bulk' transfer), isochronous cannot report errors and hence has no error correction/re-transmission. So it is possible to have fantastic data transmission but still suffer with real-time transmission. Fixes to these problems come at various price levels.
