Zavfino Majestic USB Cable

@macg19 you are correct, the key of USP cable performance is ensure no bit errors. Fundamental frequencies in USB transmission are x480MHz, which is beyond of any sound system BW, but high freq. could affect bad-shielding analog cable signal next to it. Wondering if recommended USB cable replacement passed USB standard required mandatory tests. 

esthetics, look, and feel, still does play a role in high-end audio device consumer market. 

Hey, macg19, am  I understanding you right here? Have you auditioned different USB cables  , and found no difference in sound quality?

@macg19 @1971gto455ho Until you’ve replaced your amazon basics cables or monster cable rip offs with a quality HDMI and see the MAJOR difference in your picture quality, or USB for sound quality, you will continue to deprive yourself of what your equipment is capable of. Even moderate cost quality products will show very notable, undeniable differences, from Pangea, Furutech, Jenvings Supra, etc. The differences come in too many forms to list, but include from magnetic field compression due to poor designs, poor insulating materials & dielectrics which can store EMF in their effort to reject EMF, but then supersaturate and release it into the cable conducters, disrupting electron flow (poor EMF rejection); too small a cable, causing its own magnetic field to be compressed by the insulation, and restricting its own imaging abilities; too large a cable enabling electron flow at the outer edges of the conductors, which causes separation and reconstruction of the digital ’digits’ in the wrong sequence, causing muddled colors and sound, black saturation, detail motion,,, on and on; too much skin effect in analog cables, or even stranded digital cables, enabling jumping of electrons out of sequence and a diluted product at the endpoint (tv/amp/speakers/etc). You both bash audiophile cables on your assessment and limited knowledge of electron flow, without knowledge of how electron flow impacts audio or visual signal at the receiving end. You do so out of ignorance which you believe is well-informed information, and without experience, on your personal assumption that 4k in, 4k out is just a matter of total digits.

Do what makes you feel well about your own $ and systems, but when you come someplace like here, and bash others wealth of knowledge and experience far beyond your own, you only embarrass yourselves to the point of others ignoring you, to wit, when you may actually have something useful and educated to share, no one will listen. Good day to you.

For Audio, USB protocol is Isochronous: Periodic and continuous transfer for time-sensitive data. There is no error checking or retransmission of the data sent in these packets. 

Google Gordon Rankin. 

“The three main USB transmission protocols are Bulk, Interrupt and Isochronous. Bulk (used for data transfer to a hard drive) and Interrupt are error-correcting. Isochronous (used for audio) is not.”

“Bulk and Interrupt are immediately NAK (negative acknowledgement). The receiver is designed to detect a bad packet immediately and the packet is resent.”

“For USB audio, the receiving device is basically translating a serial stream of data with a clock interwoven throughout. At the end of the packet sits some sort of block check. If the block check does not match the data then that packet is flagged as an error.”

“With Isoschronous USB transmission, packets are sent without any error correction / resending. But guess what? This is the USB protocol used for audio frames. The bad news is they are not error-free.”
