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!

Oh, and as for my personal listening, I stream Amazon UHD because Prime and Qobuz because it's probably overall the best.

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.

My preamps include a modified and upgraded APT-1 and a Marantz PM7000N.My power amps include the Nelson Pass designed Adcom 545 100W/ch MOSFET and a Mcintosh MC240.

For speakers, I have KEF LS-50s, Magnepan LRS, and Monitor Audio Silver 300 7G, as well as Grado and HiFiman Sundara headphones.

Other Sources include a VPI Prime Scout w/JMW-10-3D Unipivot arm and Hana SH moving coil and a Marantz CD6007 CD Player. 

While we’re at it, here’s another good reference

Digital to Analog Conversion

"After DAC, the analog signal is sent to the anti-image analog filter, which is a lowpass filter to smooth the voltage steps from the DAC unit.". There are numerous filter designs and theories about them. I leave it to you to conclude the best.

Concerning quantizing noise, there are four kinds: overload noise, random noise, granular noise, and hunting noise.

Overload noise is the level of analog waveform at the input of the PCM encoders must be set such that its peak value does not exceed the design peak of the quantized V volts. If the peak input exceeds V, then the recovered analog waveform at the output of the PCM will have some flat tops near the maximum values.

Random noise, This noise is the result of random quantization errors in the PCM system under normal operating conditions.

Granular noise When the analog input level is reduced to a relatively small value with respect to the design level, the error values are not equally likely from sample to sample.

Hunting noise This occurs at the output of a PCM system. It can occur when the input analog waveform is almost constant, even when there is no signal during these conditions.

 

 

@panzrwagn : thanks for describing your system. Questions:

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?
