Okay, I will give it another try. Maybe it needs time to settle.
I think it’s because those grounding boxes are silver while the CADs are black!

Or maybe a CAD is just better than a Xangsane, or maybe the MSB circuitry has a preference on USB. I need to get a CAC to compare eventually because now I am curious.
The USB grounding cable has been with MU2 for the last few hours. It needed some time to settle, or it could be because MU2 USB port is seldom in use, for whatever reason the system sounded a lot better than yesterday. But I have a Dragon jumper that is still in break in too. Anyway, the SQ is as good as before, but is USB better than RCA for signal ground? Who knows? I really cannot say for sure.
USB cable will stay with MU2 because I could use the RCA cable somewhere else. I frankly do not believe I heard a difference between the two, and it is a link for a grounding box crying out loud! Some don’t even hear a difference from a fleet of grounding devices. 
By the way, my Muon streaming cable will be here tomorrow, finally! It will go between the saterllite and SW-6 (before FO link). It supposedly be significantly better than the one I am using now, so it will test my theory that cable before (or after depending on where you’re looking from)FB does not matter. 
my Xangsane ground boxes (x 3) arrived today but without the pure silver cables that were included in my order. I hope they rectify that. I’ve used the Message center to notify the vendor.
Surprisingly, I switched the Green cable with a Xangsane grounding cable for PZ, and I like it better. So now I think the grounding cable does make a difference 
Still, I am not sure I want to spend over $100 on a grounding cable so I’ll settle with Xangsane. I need to order two more to be done.

Can you post like to the device? Seemed like limit one per order?
If you are talking about the grounding box and cable, I bought them from this site during their Black Friday sale, and I do not think there was a limit on quantity:

Thanks, do these work better individually than say the ground master in one strip? I thought the point was to make them all have same potential?
I use both. Grounding boxes for signal ground on MU2, DS MK2, and LHY SW-10, and RouteMaster (plus a GM City) for chassis ground on PST, PZ, LHY SW-6, and M1200s. In my system the grounding boxes are more effective, but it may be because signal ground is more effective than chassis ground.
Luca has the same experience with his CAD grounding boxes. I do not know if any of his CAD is connected to chassis because that would be the right comparison.

Has anyone tested whether the inexpensive option you have chosen for signal ground is equivalent to the more expensive options like CAD?
I know that others like Luca have seen the merit in the pricier options like CAD, and uses dedicated ground boxes for each unit. Just wondering if max dollar is warranted in this arena too.

I am wondering that myself. Eventually I will try a CAD, but as of now I am happy with the cheaper solution. Shunyata makes a more expensive grounding box similar to RouteMaster (one box serves many devices), but it is quite expensive too.

Yes I have a Sean Jacobs PSU chassis connected to a CAD GC1 but this linear power supply just feeds the router. Not enough to answer your question.

You are a well grounded individual. We have to give you that.

You can find out something about grounding boxes in some forums. Some say that the box should fit in some proportion to the weight of the component. Inside there is a conductive surface made of copper or silver. The larger the surface area of the conductive surface, the better. Copper foil is good and less expensive than silver. Minerals such as tourmaline are used, which can convert high frequency into heat. Some minerals or quartz can also be mixed there: rock crystal, rose quartz, shungite, carbon and many other secret components. The Xangsane grounding boxes are compact and easy to store. The CAD are larger and can therefore have more minerals inside. Donald already has a few and can also try whether several grounding boxes on a component have more effect. How much is necessary and at what point is there no difference? The aluminum boxes should have a constant effect, in contrast to wooden boxes, which should have a different effect depending on the humidity. At least that’s what the advertising for aluminum housings says; I can’t judge whether it’s true.

This isn’t a rabbit hole. Sounds more like a black hole.

The Muon streaming cable looks well-built and is heavier than I anticipated.
Here is the big screw up. When I installed the Muon cable between SW-6 and the satellite, I found the SW-6 power was off, and the ethernet cable was installed at SW-10 instead of isolated input of SW-6. What does this mean?
I have been listening to SW-10 alone without SW-6 and the Fiber optic link. The better sound I heard was all from Muon Pro and Shunyata Omega cable working together without any help from F.O. setup. This probably happened since I redo the rack arrangement a couple of weeks ago.
No wonder lately I like SACD much better than DSD256. The difference from streaming was not only due to Blue Sky update, but also, I took out SW-6 and FO setup completely.
I put in the new cable at the right place and turned on SW-6 and the rest of my system. I need more time to do any fair evaluation obviously.

If you add 400 to 500 more tweaks to your system it will require a staff of 7 to keep track of everything.

Then you now have a huge difference in your streaming chain with the NA cable and your SW6 with fiber optic compared to the only SW10.
Also try swapping Omega with Muon cables.

So far, the SQ has suffered as the result of the new cable and a stone-cold SW-6. Tomorrow it should get better.

I had a small meet at my house this past Sunday. A friend brought over a broken in, very expensive Ethernet cable that shall remain nameless. It was completely obliterated by the innocuous Monoprice CAT6e cable I have in my sound room between the wall and my LHY SW-6. Sometimes an improvement doesn’t solve a problem if there’s no problem to be solved.
