Zavfino Majestic USB Cable

@westcoastaudiophile :

Let’s try this again:

And your digital cable is … ? Amazon link please. With those measurements.

Do you stream? What is your digital setup? Source to DAC. Thank you so much!

You cannot beat Zavfino Majestic USB at that price. As good as it gets. Here is another one to add to your list, more expensive though: https://www.madscientist-audio.com/bmusb.html

New Zealand based. They have the "Ultra" version of that, way more money, but it is the newer version.

@missioncoonery : just ignore the trolls. 

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.”
 

I never understood this phenomenon. People with zero interest in USB cables pile on heavily on …. USB cable threads. With ferocity and anger. Go figure 🤔

Scan80269 as quoted from audiostyle.com, April 2017

Who is Scan80269 ? Does not ring a bell. Some type of guru USB scientist? Credentials? I looked up audiostyle.com. Site does not exist. Any working link to share on the guru?

These guys are very funny. They think having access to a "Google machine" makes them the authority on anything. Well, these are the times we live in, instant gratification. I bet they don't even stream audio to their system, or if they do, they are not using USB, at all, and never laid eyes on any USB cable other than their printer cable.

…including 20 years as a principal network architect for AT&T.

That certainly does NOT make you the authority on digital audio transmissions 

You can listen all you want and perceive all the differences you want, but they aren't in the digital cable. 

Any digital cable? And please enlighten me, where else in cables we should look for a difference maker? 

Again, working for ATT makes you no expert in digital audio transmission.

Do you stream music? If you do, how? Can you please explain your music streaming setup, from source to DAC? Thank you. Maybe I can learn a thing or two about digital communications 🙄

Panzer Battalion @panzrwagn :

T-1 (1.544 Mbps) and T-3 (45 Mbps) in the early 90s to OC-12 (622 Mbps) circuits in the early 2000s. And by 2008 AT&T had upgraded over 80,000 miles of carrier backbone to OC-768 IP/MPLS 39 Gbps.

Well sounds fancy for good old ATT. What does this have to do with you and your expertise in streaming audio?

And you never answered my question. Let’s do it again:

“better” cable/s without any technical data to back it up aren’t really “better”! 

What technical data do you look for when picking your cables? Thanks 

@jerryg123 😉

Panzer Battalion: you are talking about USB for audio, right? I already explained it to you how USB works for audio transmission, not going to do it again, as it sounds you are unwilling and unable to read anything that does not confirm your beliefs and dogma.

And you never answered my question. Let’s do it again for the third time:

Use measurements if you will, but IME the final arbiter is what your own ears tell you in your own system

With all due respect, this has nothing to do with listening. Or measuring. They measure nothing. They just read about measuring on the internet.
 

From my experience dealing with these folks, more often than not, these folks don’t even have a stereo system at home (other than an Alexa style speaker, AirPods, or car audio). And often they don’t even like music. They just like to play the audiophile in the audio forums. So you are just wasting your time. Me too, but I kinda of like it, it’s a good exercise is psychology and human behavior

for digital interconnects I choose cables with best EM shielding 90dB+, lowest diff-common mode conversion, common mode filter, lowest Tx-Rx crosstalk,  freq. dispersion, and lowest insertion loss at least at 6th clock frequency harmonics. typ shorter cable is better. 

Great and dandy!!! And your digital cable is … ? Amazon link please. With those measurements.

built of military grade bulk cable and professional terminations

Hmmmmm…. Military Grade Bulk Cable. That’s a first. Never heard.

Any links to these please. Or are those only available to members of the Military?

I am guessing those military grade bulk cable rolls have those measurements available? Or you measure and sort through all cables to determine “lowest” yourself? If so, what measuring instruments do you use? Thank you

@panzrwagn : You never answered my question. So here we go for the fifth time:

Do you stream music? If you do, how? Can you please explain your music streaming setup, from source to DAC? Thank you. Maybe I can learn a thing or two about digital communications 🙄

Great. You really think I would open your links? 😂

@panzrwagn : 

You never answered my question. Perhaps you missed it. Let’s try again. So here we go for the sixth time:

Do you stream music? If you do, how? Can you please explain your music streaming setup, from source to DAC? Thank you.

@panzrwagn : thanks for describing your system. Questions:

My DAC uses the AK4490 DAC chip set to an unstressed 24-bit / 192 kHz (or DSD 5.6 MHz) in deference to the extra noise likely to be an issue at the full 32-bit / 768 kHz (DSD 11.2 MHz) implementation

What is your DAC? Brand / model? what chip a DAC uses is of very little importance, it's the implementation that matters. I have a feeling it's a China DAC, topping or similar, but hey, zeroes and ones, right? Any $2 DAC chip competent enough would do?

I stream Amazon UHD because Prime and Qobuz because it's probably overall the best.

Question is: HOW do you stream? Your DAC has a network bridge built in? If not, what is your streamer, and how are you connected to the DAC?
