Brought in by Tony last week. Currently Pre Production prototype. A little box the size of a big paperback and a Beresford DAC. Pick it up carefully, it weighs a *lot* with Tony's BD version of Unobtanium as a big cast lump inside. Black body with a brushed aluminium front - so room for improvement 5 sockets on the back for grounding. Takes 5 connections via RCA and 5 via spades. Nowt else apart from Black Ravioli feet. I knew about Grounding Boxes and was sceptical. Happy to listen to boxes Tony brings around though. My standard system set up. Played a track. All fine. Plugged a cable into the Isis CD and the RTZ. Into the less than ideal digital socket Tony said. Subtle improvement. Difficult to pin down as everything seemed subtly better. You wouldn't pay a lot of money for that sort of improvement. Plugged into an input socket into the Belles Pre. Shock ! What an improvement. Almost lost for words. Detail, bass, soundstage, mid - everything improved. Now plugged into an output socket of the Belles. More shock. Another big jump up. Logically the more you plug in the better more music delivered. Kit swap around with Isis replaced by TAD CD direct into Tony's own Power Amp. Tested and found the same. Best when grounding is taken from 2 sockets on each box. You have to hear it to believe it. Budget price £1500 plus cables Entreq do them for a lot more dough

RTZ. Is that what your bank balance does? Reduces To Zero. Does the connecting cable type influence the sound, or is just an electrical connection all that is required to connect to the grounding box?

I'll remain open minded. I'd like to know what a grounding box does, exactly. It's a little small to be The Earth. So how does it work, or does it just fix existing grounding issues?

Just to clear up any confusion the RTZ does not connect to mains EARTH at all in any way.
That is a different aspect all together and requires a somewhat different approach.

Is there a risk of ground loops?

Some equipment has a floating earth, others have no ground connections, you are talking about earthing the individual equipment cases together?

Most surprising and very good. Cables recommended by Tony are his Coherent 4D which I am guessing around £200 each.

The cable connects only the outer of the (EG) RCA socket to the RTZ.
I'd need to be talked through the tech again, slowly, to understand it.
My ears said the effect was very good

Thanks, Tony. So does the box somehow emulate a massive but clean ground connection?

Morning Martin That's the badger You have listened to an earlier version of the RTZ many times before on visits here, in fact the RTZ has been in the system for five years, attended many shows, due do its discrete size it can be tucked away from view, unlike others which are much larger and more costly Recently re-visted the project and the box that Mike listened to is the result of this, UK designed and built.

Ok, thanks. One to investigate for the future.

Is there any possibility of seeing inside this box? That is to see what mysteries it uses between those cables. In a PSU one can see a transformer plus other parts.
As ever I am sceptical whenever great wonders are said to be achieved. Whilst not a PhD in Electrical Engineering I have some understanding of electrical matters beyond changing a fuse.

Hello Alan
There is no rocket science here, just grounding principles taken to a particularly conclusion which produces the desired results
Vertex Aq, Entreq and Nordost all have products which claim do produce a similar condition
However on this occasion measurements will tell you what you need to know with these products.

Fluxed or anyone else
So no picture which would be worth 1000 words then? I continue to observe reactions. I am not experiencing much that I would perceive as benefiting from such a device.
Thanks

I saw the outside of the box. Was surprised by the sheer weight. Heard the results as above.
Don't need to see inside which is unlikely to mean much to me anyway. Some cables connecting to a block of something. Much like any bit of kit I have

This is something I will be investigating in the future. I’m intentionally read of more people’s experiences.

I've read a lot about Entreq and seen some keen reviews. It's an area I shall explore when I'm done with noise reduction, which is a rewarding area to get sorted first.

The RTZ has landed. Comparison without and then adding in cables one at a time to Isis and Belles Pre then TAD CD and Belles What does it deliver ? Everything in spades. PM me for a visit and come and listen yourselves, North West Surrey Easy to demo : Take out all the cables. Plug them back in one at a time - bonkers uplift in sound quality No brainer even though it has a silver front Tony even sorting that out for me though Can hardly believe what I'm listening to at the moment. Currently averaging 76db but sounds so much louder Now 99.99% of my music needs to be listened to as new
