Aha! Thanks for that, Tony. I thought I may have broken some pre-launch agreement back there for a minute!
I will review them properly when I have time, and photograph one, too. I think that using them with the Asus and Mutec has confirmed in my mind that a) there is still residual noise to be removed even in a carefully built digital path and b) such improvements in the digital chain still have an amazing effect on the resultant sound quality!

As I demonstrated before, both, the source, re-clocker and dac or what ever you have in the replay needs to be connected to the same ground,even the clock as well,all require the same reference point to maximize performance
Shame you just cannot use more outlets on the SGS I would feel you would would improve over this simply as you are tying in all of the components to one single point
The BR ground blocks are good product, for those not wishing to go the whole way with a dedicated grounding box, the only issue some may find is that having a small 3 x 3 metal box behind each component maybe restrictive space wise

The early models of BR grounding boxes/modules are totally different from the launch models which MT has, I left out the hdmi one as wall mounted TV's wont take them due to the size, I tried it in a sky q box and a 55" Sony on a stand and they work very well on those. Takes 2-3 days dont know why for them to do their stuff on AV gear.
There is a mains one as well which I have tried.

Two observations: 1) the BR grounding boxes take about 60 minutes to come good, not as long as the SGS but there is still that slow improvement over a period of time, something I am well familiar with now. Disconnect them, though, and the negative effect is immediate. 2) there is no equivalent effect to the SGS where only one box worked well in my system. Using two was counter-productive, but at least that led me to using one of them on the router which proved to be a good move. No such effect with the BRs, which work well individually. I kept clear of the DAC and buffer, which are already grounded by the SGS (four leads is the maximum I can connect to the one terminal, three spades and one 4mm plug), targetting the Asus and Mutec. Luckily, David sent me the exact pair I needed, one USB and one phono. Or perhaps it wasn't luck and he studied my system very carefully  |

Forgot to mention there are no orange fuses in the BR products anywhere LOL

I made a small change by swapping in an SR Orange fuse into the power amp cable from the Blue I had in there. That's better, a further lift in detail and attack. I definitely prefer the Orange and Red over the Blue. Interesting how these things work out, and I can see a good reason for using Blues in systems that are just too forward and need calming down a little.

It's all about the right balance though, isn't it? Two Blues for the power amp (it's the only component I have left which is still double-fused in cable and rear panel) were just softening things too much. An Orange and Red have restored the balance nicely.

Grounding Thoughts
There is so much to get right with grounding and I can't help feeling that we blunder around, sometimes happening on a good setup and other times wondering why we can't. Much of it has to do with residual noise on grounding planes within components, I am fairly sure, and preventing it from superimposing onto the precious musical signal.
Getting mains safety earth right is a good start. If all your components have a three-pin connection, then they should be properly grounded through the supply. If you have a distribution box or regenerators, like me, the supply should still provide earth to each component and provide star connection back to the house earth. At this point, there should be no hum. If there is, there's no point going further until you fix the ground loop causing the hum. If you have a floating component due to a two-pin connection, it may need grounding or else it may be double-insulated or Class 2, in which case leave it alone and it should acquire a baseline ground from the component it becomes connected to.
Here's where it gets complicated. If you use a grounding box, the commonly understood methodology is to connect everything back to that single grounding box with as many wires as you feel necessary. Indeed, I found in my own system (thanks to Tony) that running two SGS grounding boxes (to different components) was counter-productive and hurt the sound quality. I re-jigged things to redeploy one grounding box to my internet router (where it helped) and the other to ground system components. However, I have a limit of four connections so I grounded only the DAC and buffer from this box. However, then along came these cute little Black Ravioli grounding boxes with a single connection and an obvious philosophy of one box per component. I thought, well ok then, let's use them to ground components which are not currently connected to a grounding box. So I deployed the USB one to my Asus streamer and the phono one to my Mutec reclocker. And it worked really well!
So is the single central grounding box with multiple cables a better approach, or the BR style distributed grounding box per component better? I haven't a clue, and have ended up with a hybrid of both.

Scots article is not quite the full story though imho
Which do you feel works the best Dave? Scots or Derricks approach?

I've used some Christmas Amazon vouchers to order an Audioquest Cinnamon USB to microUSB 0.75m cable to power the Asus from the QP-1, replacing the JuiceBitz cable in that position. That makes all of my digital cables come from the Audioquest stable.
