The dedication you put into tidying up the chaos behind the rack makes cable management an art. It is a challenge that requires patience, discipline and endless effort.
Zen and the Art of cleaning up the Big Mess!
An inscrutable force against which I constantly fight, to which I have now surrendered, knowing that I am helpless in the face of the inevitability of my fate! Behind my rack there are dark forces that I will never be able to dominate!
An added benefit by moving the switches in a separate rack was that I could make better arrangement of cables and power cords. Also I moved the satellite further away (still waiting for the streaming cableš¤¦āāļø).
Too early to tell if thereās SQ improvement, but I like the look.
Today I received more grounding and interference suppression products. The Xangsane grounding boxes like Donald has havenāt arrived yet. I attached the Akiko tuning sticks to my speaker cables. Since my Furutech DSS-4.1 speaker cable has a copper foil shield, I thought it wouldnāt be a bad idea to use the Akiko Sticks to remove interference on the shield. I would have to do another A/B/A test after a few days. I imagine that the sound is cleaned of RF interference in a similar way to the Akiko Sticks on the speaker cables, as the GP does with the input current. I still have to find a place for the other interference suppression parts.
Iāve had a round audio support ground box on my Cambridge Edge NQ preamp/streamer combo for a few days now. The first impression is that the sound increases in resolution. For now, I decided to attach a second one to the case. It seems that two do more good than one. Iām excited to see what the Xangsane grounding boxes that Donald liked so much will do.
Greetings Andreas
I received two more Xangsane grounding boxes, so I put them all in use during rack setup yesterday. The system has only been on for a few hours, and I can say the new setup sounds quite a bit better than before. The biggest improvement is in smoothness and a dead-quiet background (probably mainly due to additional ground boxes). I heard better focus too (and that could be mainly due to the new setup).
The biggest improvement from a single box was from DS MK2 DAC (connects to RCA output), and MK2 sounded amazingly quiet (that I didnāt know was an issue before). The SACD is now sounding better than streaming again. These grounding boxes are more effective to be used on DAC, streamer, and switch I believe.
In the picture you can see all my grounding boxes are on a separate wood block behind the main rack, and two LHY switches are in the back too.
My wife likes the new look too. The SQ is as good as ever only after a few hours of running from cold, and Muon Pro continued break in, new grounding boxes, and rack rearrangement all contributed, I am sure.
The midrange is above rack now. 
Donald, I like it a lot better now too. 
Now you can see out the window again. Before, the tall and wide rack was very overwhelming. When cleaning windows you just have to be careful not to trip over the cables and boxes. 
What is the metal puck thingy on the front of the speaker stand?
That is Lucaās favorite voodoo, Origine B2, to align the water molecules. I got four because CA is dryer, and you at East Coast need eight or more. 
It takes 24 hours for all molecules to connect each other so be patient.
Luca has either 12 or 16, and he said it is the best tweaks he has had in room (but he said that on too many).
Oh yeah, it looks very nice.
May I ask you:
Iām thinking you can go even lowerā¦
It is a TAD Purifier, and the only thing connected to it is an Orbi satellite and iPad charger.
The two black boxes on each side are the essential CD binders that I seldom open now. The main purpose of them is to prevent iRobot vacuum running into the back area. It could do more damage than rabbits.
On perplex grounding scheme, I am running ground boxes to signal ground (MU2, MK2, and SW-10 switch), and RM/City to surface ground (M1200, PZ, PST, and SW-6 switch). I really do not know if this is the best arrangement, but at least I am separating signal and chassis grounds. In my system the signal grounding devices are way more effective. That is how I remember what you had on ground setup too.
When I get my next amps (such as BHK600s), they will fit in the rack (M1200 now) with one inch spare. So the setup would look better (in silver 
).
Used Mapleshade Gibraltar speaker stands for my Anthony Gallo Acoustics Reference 3.1 Speakers.
Should add a bit more stability and some height (improved HF driver alignment w/ my earsā height) vs my current spiked butcher blocks.
If they sound ābetterā, that would be a bonus.
Should have them in a few daysā¦

Do you really need it?
In your shoes Iād place:
M1200s (600s) on the lower shelves.
PZ and MU2 on the middle shelves.
PST and MKII as it is.
As for grounding, I like your set up now but canāt understand: I suppose that RM/City used for chassis ground are connected to the ground lugs of PZ and M1200s but why PST and SW6? Do they sport a ground lug on the back?
Insane 
I suppose I do not need TAD, and I can just plug the satellite and charger to the wall. But I am worried about AC pollution from them. I may change it later when I get new amps.
I have too many spared green cables, so I use on spade cable connecting to a screw of PST, and another to the top surface of SW-6. Frankly I have not evaluated if they help or hurt the sound, or doing nothing.
Thanks, it makes sense and youāve already done a good job with your rack, like it!
As for grounding Iād consider the MU2, MKII, PST and both SW the noisiest components to treat. I mean Signal Ground in this case. Therefore Iād recommend a single grounding box for each of them, using the available port as close as possible to their chip/board:
MU2, MK II and PST use a USB A āserviceā port
SW6 and SW10 inevitably use a RJ45 port
each one with an appropriate terminated grounding wire of the same model and length
On the other hand Iād consider Chassis Ground exclusively for M1200s and PZ via their own ground lug, where Iād suggest to use the same grounding wires (model and length) terminated with the appropriate spade size plug, each one connected to RM in a star scheme. And finally the RM connected to the City.
I really donāt like the Puritan green wires, canāt say for the Xangsane ones. You donāt need fancy expensive cables but Russ Andrews wires cost less than 100 US$ each, taxes and shipment included.
Youāre an early riser just like meš
I agree the green lines from RM are not that good, even the connectors are cheap ($75 each is crazyš²). The Xangsane ground cable is very nice with silver plated spade and conductor, and I ordered a USB one to try on MU2 later. Although I have not tried a side-by-side comparison between the two, it was clear to me Xangsane made a more noticeable improvement on SQ than before.
But even green line makes a difference. Earlier I disconnected it from a back screw from PST, and there was a reduction in clearness of SQ. At first I was not sure, but after adding it back to PST, I started to hear better sound after 15 minutes again. Itās interesting because itās connected to chassis ground that I was not able to hear SQ change before. But with the latest setup I could. Signal ground may make even more difference, but I need another box.
I just find out ZenWave makes grounding cable too. Hereās comes more rabbit holes on cables.
Nice Al! Iāve been wanting to try direct drive. What cartridge are you using?
Just a sharpened chunk of bamboo.
Maple sounds better
I thought maple tastes better.
Maple sounds better too???
