Seems that ferrite chokes are effective in EMI and RF reduction. Some research I did has indicated it can effect the rising and falling edges of the data square wave.I can't a/b a usb cable, and I would not trust myself. This newer cable though looks much more sturdy and resistant, and will not be kinked. It is just a good usb cable, shoud sound good cause not gonna spend more on such cable. Just by physical construction, has to be less prone to interferences or catching noise, I guess. And anyways, if it's gonna go to a busy cheap usb 3.0 hub... gotta fix the firmware problem first.
You can even buy "snap connectors" and create your own ferrite treatment. The grounding is apparently tied to both ends of the usb connector. This goes to show that you should ultimately always consider that the source can be noise (switching power supply, laptop, fan motors) so this is where you must look at all of this as either being preventative in passing nasty signal or fix it ........ Now you see the reason there is no real way of fixing noise without using a DDC.
Small handful of people will use a hardcore Precision master external clock for their DACS. Not many dacs have provisions to accept external clock.
Last week I've decided to remain on cascading 2 of my Mutecs. My 3rd was on order. I've painfully shifted gears, taken the step on ordering an external Mutec Ref 10 master clock. This will now feed 10mhz clock to both mutec Mc-3+ USB units. So I will bypass the internal clocks of the DDC. Feeding both DDC units external clock signal. Such a process will provide redundant isolation of signal via xformers in the coax connection. Also the precision clock from the Ref10 will be more than sufficient in creating my personal "ultimate" square wave signal. This is where my insanity will stop in all of this source cleaning. Even the non SE version of the REF10 is ruffling feathers of DCS clock performance. I am just glad to have initiated some research for others. First and foremost is to enjoy music. If you create your happiness, that's what matters. The DDC talk is just allowing you to understand that thinking out of the box has created a great upgrade path you probably never knew.......
I'll admit due to covid, I've become obsessed with this source stuff. This is where I have discovered a new level of sound without adding new audio gear. The new fun stuff I've added in tube gear has been an additional adventure. Source is still the key.
