Entreq Tellus grounding

It would be easier to build a John Windt "Hummer Tester"

Build the “Hummer” to Find “Pin 1 Problems” in Equipment AS032

The John Hummer probe can not be used to find ground paths in RCA plugs as requested by the OP.

Are you saying that if you just disconnect the Entreq for a few seconds and reconnect it the effect diminishes significantly?

I have not disconnected for few seconds but when I disconnect it to do maintenance and cleaning, the entreq effect does diminish. Typically such maintenance sessions last at least an hour. I have ordered some ASI grounding cables to try. Someone with entreq grounding experimented with the ASI to good effect. The reported benefit was much better instrument placement and separation and an even lower noise floor.

Interesting and thank you for sharing. I did not discern much of a difference between grounding input rca vs output rca. I think they are quite close but as with entreq grounding it takes about 2 days after connection to hear it's full impact and maybe that's why it's difficult to do a AB comparison.

If the RCA jacks are connected directly to the chassis then there is little difference. Theoretically the input jacks are better.
But if there is a plastic insulator ring and the RCA jack, then all bets are off. We don't know what long path the wire and maybe resistor may follow inside the box. Your grounding wire could make a nice interference antenna.

What is meant by the above?

 

[Speedskater]

Because these RCA jacks are not directly connected to the chassis/shield the wire to the grounding box may act like an old-fashioned automobile radio antenna.

Hi.
I would be interested to know what kind of maintenance you do. Is it just about the Entreq boxes, about other devices?

It is why I advised on using a simple technique to ascertain the grounding scheme of the device...

But anyway, no one knows how these audiophile grounding devices really work, or even the fundamentals behind them - but the users tell us that they change subjective sound quality. So all this technical talk is mainly entertainment and fantasy, users should try all safe possibilities and decide for themselves, or believe in the experts on these devices!

+1.

when these grounding threads descend into the 'why' or 'how'; I put them on ignore. it's been so obvious as to what they do in my system. for me it's only a budget question. I'd like to add more pieces here and there I know will yield results, but presently have other more pressing priorities.

once a system is reasonably settled and mature; grounding is a significant way forward to pursue. as far as grounding the negative speaker terminals of any amp with the Poseidon or Silver Minimus.....as these pieces are not connected to anything there is no risk. it's just common sense. obviously one needs to be careful not to accidently cross the negative and positive or connect to the power grid.

These recent posts bear out my own experience of the benefits you get when moving up through the range of Entreq earth cables but I am aware that it is not always the case. Apollo seems to be a generally safe option/upgrade but the Atlantis does not suit all systems so a try before you buy.

Mine are now mainly Atlantis and Apollo and they have been well worth the extra cost.
For negative speaker terminal grounding I use a Poseidon/Atlantis with the third terminal grounding the amp itself. One of the most successful Entreq applications in my system, The sound really opened up.
My most recent Entreq addition was an Olympus Tellus with an Apollo mains earth lead and that too has made a clearly audible improvement to the sound quality and I can highly recommend it, but if you go down that road it really is a two person install unless you really are big and strong. The wooden box it comes in is large and awkward and together with the Olympus itself a two person job.
Marc if you do try one be warned cos getting it up the stairs to your listening room could leave you needing the services of a professional colleague.
Jonathan I am so glad to hear how well the Silver Minimus has fitted in to your system. Amid all the discussion on the more expensive Entreq components it is a very timely reminder of how effective the less expensive options are.
I'll look forward to reading more as they settle in.

Barry, understood re the 2 man lift.
Can't be as bad as carting 110kg Stacore up the stairs LOL
Twice! LOLx2 NOT!
For me, my experience w Entreq in the new, quieter space w purpose built feed to the audio room and dedicated lines has not been as dramatic as in London, although still very useful re maintaining bloom and opening up depth and staging.
My efforts and directing of funds going more now twds vibration isolation ie more Stacores.
I'm glad to see the Entreq thread you and I helped establish is going from strength to strength.

 

[Barry2013]

Thanks Marc
Look forward to reading of your continued progress with the Stacores.
Best
Barry

I was cleaning all my contact points with Kontact cleaner.

6mooms review for Gutwire grounding says that grounding boxes have to be shaken every 6 months because they get saturated.

I assume they're referring to entreq. Anyone find this to be true?

 

[spiritofmusic]

Good luck to anyone shaking the 50kg Olympus Tellus

 

[Barry2013]

Yes my immediate thought too Marc!
Vert are you sure the reference is to Entreq grounding boxes?
I've been using them for 3-4 years now from the Minimus right through to Silver Tellus, Poseidon and Olympus all supplied by an Entreq expert and he has never suggested that they should be shaken.

I don't know for sure, but I assumed so since entreq effectively solved grounding for audiophiles.

I sure that started as a joke, but the 6moons reviewers are extremely gullible.
Reality is not part of their world.

Crikey, mine are still going perfectly fine. They've sat still since I installed my HiFi Racks shelving many months ago. And they've never been "shaken", though I do find their musical contribution very stirring.

Hah...very well said!

I'm doing a review of the Synergistic Research products and I can tell you that when I used the ground planes on the cables, the sound definitely improved. Grounding components and cables makes a real difference. I will trying the new active ground block in the Fall.
