Zavfino Majestic USB Cable


I am planning on upgrading my $50 straightwire usb cable to something under $300 and came across the Zavfino Majestic USB. The specs look great but I can’t find any semi-detailed reviews online besides on their website. 
 

Has anyone tried this cable? What are your impressions? Thanks!

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.”

differentiated by specification/performance or price? 

@sfcfran Dude...all I said was...

Curious why you want to upgrade a USB cable? They either work, or they don't.

Better aesthetics I can definitely understand, but there is no way a more expensive USB, ethernet, or HDMI cable can change the sound (or the video quality), assuming the cable being replaced is functioning properly.

...and you and others have jumped to conclusions such as I use "Amazon basics cables" and have a "less revealing system than everyone else here".

I'm not saying don't buy good quality cables. I do. But when it comes to really high-end cables, especially digital, the marketing around many of these things is simply BS, and of course no one wants to admit that once they've bought them.
