I use a grounding box made by Robert Bastani. It's sealed and he won't say what's inside it but I know he's into Tourmaline and various chrystals, he even sent me a bracelet to wear!. I've taken the box to other systems and heard similar improvements, it's kind of subtle but important once you're used to it.

Now that I've tried the Quartz Acoustic boxes to my power amp output negative terminals, I can say that grounding at the power amp works well for me.
Characteristics are overall tightening of the sound, high degree of detail, speed and dynamics.

Keep reporting back in case the effect improves !

Will do, tonight should be interesting as most of my boxes need 24 hours to settle.

A quick update
I ordered another long grounding box from China
I had a theory that my DAC would benefit from another grounding box. I already use the RTZ on the A22. However theory and practice don't always match and this was a backward step losing focus and coherence. So I added to my spur that feeds the DAc and Berhinger. That is a bit better the usual sense of increased depth and flow.
Next step will be to replace the BR sticky pads on the Temple monos and move them to grounding boxes The Temple will get the BR big feet within the next week

Differences are not big suggesting to me I don't really have more to be gained from extra grounding

We're all discovering as we go along
One or multiple grounding boxes could be the optimum and it could be even more complicated.
Do different systems and the house electrics react in different ways...?
I bet there are other influencers.
Neighbours over the road are having serious building work done and a delivery truck kindly pulled their overhead electric cable down.
Electric people came to fix and said they would replace the overhead cable as it was very old and they use different, lighter (better ?) cable these days.
Neighbour has decided he would rather have the cable underground and has a digger on site anyway so another change.
They are not into hifi and it is a bit much to take my system over to test before and after but I bet he gets 'nicer' electricity
I asked him to get them to pop over when they do his cable

Like John I've found that the system likes multiple grounding boxes on the mains earth: my Silent Point at the consumer unit and Quartz Acoustic into the P10 earth are doing a great job. Last night I played a Mozart Requiem and experienced the biggest depth I've yet heard from my system.
However, I also discovered that digital components like a single box only. Multiple ones on the same component gave me problems every time I tried it.
For value for money, the Quartz Acoustic boxes are outstanding.

I am glad our experiences are the same Martin

I played with the leads on the A22 it definitely likes the USB and AES going to the RTZ more depth and texture and not subtle The coax input has no real impact I can hear

Yes but you use the AES with your Mutec and I have spare as just Bluetooth

AES was the input I had the best results with when I used to stream from the Mutec

I can't vote because I fit in the 'I haven't got around to it yet, but have an open mind on the subject'.

Give it a go
You will like the improvements !

Give it a go You will like the improvements ! I'm sure I will, but I have to pay off my speakers first! I borrowed money from the joint account so have to honour that. There's a tonne of tweaks I want to try out and grounding is up there at the top. Bit OT: Don't tell Jess, but I'm toying with the idea of giving my new speakers back and getting their big brothers, means I graduate from dual 10' to dual 12' drivers (105 to 175 kg!). |

Be interesting to know how you will get the new bigger speakers in without being noticed, I could do with some tips for future use.😊 |

Honestly (I would never actually do this) but I wonder, given the ones I have are so large if I could just swap them over and see if she noticed  |
