Static noise help please

Spencer - Wasn't trying to generalize about all Gungnirs - but can see how what I wrote could be understood that way.  Had I written "The Gungnir in MY system does not have a USB input.", things would definitely have been clearer.   Good clarification.  

Eddie - I can't compare that galvanic isolator to the JitterBug.  Sorry.  The JitterBug is only $50 or so from MusicDirect and they do have a (60 day?) return policy, so you could try it and send it back if it did not fix your problem.  

Schiit also makes something called the "Wyrd USB Decrapifier".  $110 from Amazon.  See link here:

I take it you have tried other USB ports on your MAC as well as moving the Modi from near the monitor, etc. (as suggested on that Computer Audiophile thread).

ghosthouse, Yes, I tried all USB ports on my Mac and the Modi is far away from the monitor but still got static.  Will see if the certified USB would help but I don't think it would, well I will have to try.  Will report back when I the new USB come in.
Thank you,
Eddy

After been reading so many posts and many searched, my conclusion is Dirty power (5V) from computer to the USB.  So my plan was going to cutout 5V +(Vcc) and -(Ground) cables from USB and will only run Data to DAC but found out that all Schiit needed 5V from USB.  

Eddy, now you are getting to next level in computer audio learning. Yes, noise from computer passed to dac via usb is a HUGE problem. That's why Schitt makes Wyrd(which I use), even better according to many is Uptone Regen. Other things like iFi cable with separate power and signal legs all are trying to deal with this problem. Computers are noisy, since they usually are running many processes all generating noise. Many audio software programs, try to get the computer to turn off other processing to quiet down the computer so less noise goes to the usb/dac. 
IMHO the most exciting development is the newer ethernet streamers that let you replace your computer with a small low power low noise linux box and stream your library from a network attached storage (NAS) drive located in another room and attached by ethernet cable only. 
This is a rapidly changing corner of the audio world. IMHO, Sonore, Uptone, Aurender and other companies moving in this direction are leading where digital high end music is evolving. Cheers,
Spencer

Eddie - I'm guessing you will be wanting to try a "double-headed" USB cable that separates signal from power.  The one from iFi (Gemini Dual Headed USB cable $265 for 1.5M on Amazon) is kind of pricey, I think.  There are some lower cost options.  

I bought one from a seller on Ebay [Doukmall (China)].  At the time it was only $59.  I use it with an inexpensive Enercell 5V AC/USB converter.  No noise and things sound great.

Here's a link to the latest from Doukmall.

Looks like the price has gone up but still cheaper than the iFi.  If you are skeptical about the quality of the power from the Enercell you can try the Wyrd from Schiit.

Here on A'gon there is a seller robpriore who sometimes lists a "USB Disruptor".  It is also a double-headed USB cable but he sells it with a power supply and the price was previously only $74 or so.  I don't see it currently listed in the usual Digital/DA Converters category so you might want to drop him a note and inquire about current availability.  

Here's a link to a discussion about it:

Hope this is of use.  Good luck.
