Entreq Tellus grounding

[Audiocrack]

I have not tried signal grounding yet in my systems so I asked Miguel of Tripoint Audio how the Tripoint Troy or Troy SE can be best used for signal grounding. Miquel was so kind to respond and he answered as follows:

"Different options when using the Troy Signature for Signal Grounding.

1. Find a unused RCA or XLR input at the back of your component. Pre amp is the first place we recommend you start. RCA and XLR termination grounding cables are available as a special order through Tripoint Audio.

2. Have a local technician create a internal Signal Ground wire scheme. This will require for you to add a separate Signal Ground dedicated binding post in the back of your component.

If you have a ground cable that has a spade to spade termination and want to experiment you can locate a unused RCA jack on the back of your pre amp and let the spade cradle the outer diameter of the RCA jack assuring you have a good contact point on the neutral ground.

Make sure to experiment with different grounding wiring schemes as different components will yield different results due to every component having a different grounding topology. DON'T MIX EARTH GROUND LEADS AND SIGNAL GROUND LEADS AT THE SAME CONTACT POINT AT THE BACK OF THE TROY SIGNATURE.

Happy Listening
Tripoint Audio"

Sure, thats fairly self explanatory. The fact that rca or xlr terminated ground cables are a special order and not standard from Troy does seem to suggest that signal grounding has never been the main approach from Miguel, but chassis grounding predominantly. My rca, and esp xlr jacks, on my components can not physically support a spade termination, and not many would be happy to hardwire in a signal ground, so maybe the differentiation btwn Troy being chassis-ground and Entreq being signal-ground is still a reasonable differentiation.
I say this esp since Lloyd does both in his system, both approaches sounding totally different from each other, esp the synergy btwn the two.

so maybe the differentiation btwn Troy being chassis-ground and Entreq being signal-ground is still a reasonable differentiation.

If the Tripoint boxes can also be used for signal grounding with appropriately terminated cables, can conversely the Entreq boxes also be used for chassis grounding? Has anybody tried this?

Chassis grounding is primarily safety; in other words draining static and dangerous voltage related issues-problems that may occur.
So solutions relating to this must be integral to mains distribution type solutions & products; and this comes back to many other threads on this subject that also cover safety considerations.
Personally I would go Entreq + either ISOTEK/ISOL-8/Shunyata/etc/mains regen such as PSAudio/etc.
But that is just me

Good point. I guess that the lack of a connection to the AC ground (as provided by the power cord on the Troy boxes) precludes the use of the Entreq boxes for chassis grounding?

 

[spiritofmusic]

Apparently Entreq can be use for chassis grounding, using Apollo or Atlantis spade-spade ground leads, direct to chassis screws a la Troy. But it seems primarily to be designed to connect to component input/output jacks, hence signal-ground. I simply note the non-availability AS STANDARD of rca- or xlr-terminated Troy ground leads means it surely is designed as chassis-grounding primarily.
Lloyd on these forums is one of the few that are using Entreq as signal- AND Troy as chassis-ground, getting better results w/both systems than each alone, the synergy seemingly different than when each system used solely.
I'm aiming to listen to an Entreq Cleanus which will plug into my Westwick 8kVA balanced power transformer, connected via an Apollo to my Silver Tellus, and this may be a way of grounding the mains Entreq-style, a la the Troy which plugs a captive PC into the mains.

Entreq Silver Tellus & Atlantis

John, I noticed the recommendation of putting Atlantis on top of Silver Tellus . Any reason for that ? Any difference if the units are connected side by side ?

The umbilical of the Atlantis is short by design. It is intended that the 2 boxes sit in close proximity. As I write this, I have only second hand information as to the purpose. So, I will find out from the manufacturer and get back to the forum.

The Entreq Tellus series of grounding boxes address the signal plane.

The Entreq Cleanus product, like the Tripoint, addresses the ground plane.

From the Entreq website:
"Cleanus works as a separator and eliminator of high current frequencies. Cleanus should be connected to the wall socket or to Powerus. For even better performance connect Cleanus to a Tellus with an Ertha cable."

Hi John,
yeah, the post your quoting of mine is specifically in response to a person mentioning chassis ground/SE; my concern is people messing around with a safety earth incorrectly.
Earlier I mentioned how Entreq products recently discussed primarily relates to signal ground: http://www.whatsbestforum.com/showt...llus-grounding&p=290393&viewfull=1#post290393

Hence why I feel it makes sense combining Entreq (for signal) with a filter/regeneration mains product.
Sorry if it does not read like that, and yeah I should had mention the Cleanus.

Thanks
Orb

Orb, I run my Silver Tellus in assocn w/a Westwick 8kVA balanced power transformer and Burmester 948 power conditioner. The transformer is plugged directly into an unswitched wall socket run from a dedicated radial circuit and isolated circuit breaker. From the transformer I plug in my power components: SET monos and Zu Def4 Hypex spkr sub amps. I then feed my Burmester 948 into the transformer, and from the 948 run my non-power components: tt psu, Straingauge cart RWA batt psu, both mono preamps, cdp and av components. THEN I ground via Entreq each component. Hoping lastly to mains ground the whole system by running a Cleanus into the transformer, and an Apollo ground lead back from the Cleanus to the Silver Tellus.

Now we have heard Per's recommendation I would be interested to hear if you can detect any discernible difference from stacking to side by side placement.
I use them in the latter configuration very successfully and would find it difficult to stack on top of each other so not overly enthusiastic about changing but look forward to reading how you get on.

Entreq Silver Tellus & Atlantis; stacked .vs. side-by-side

I will be happy to relate our experiences here once we have enough stock, again, to do this testing. I've yet to have the opportunity to even test an Atlantis with a Silver Tellus.

The Silver Tellus with Atlantis cables was mindblowing when we demoed it at Christian's. We found a few interesting things as well during the demo. One was that "doubling" up on the right and left inputs of the phono stage made a dramatic improvement vs. just one Atlantis on the input. The same was true for Chris' preamp-both of which are "dual-mono". As far as stacking vs. side-by-side I would guess that one would have to try both placements and see for themselves. Also we had the Silver Tellus on the floor with Stillpoints Ultra 5's underneath. We did not have the ability to place it anywhere else. I would think that what you place it on would make a difference also.

Great stuff...and yes, I placed the Silver Tellus on the floor, on an Auralex and then on Ultra SS...and it was noticeably better on the Ultra SS. Specifically, clarity and density of note improved.

Stillpoints under the ground boxes have benefitted my system too.

I wish that was not the case. I am tired of buying stillpoint's ! Once I think I am done, someone with a signal grounding box espouses benefits...lol

I hear you!!! I am literally done with isolation on the system, other than [maybe] some mass damping for the main speakers. But then I discovered the Entreq AC wraps...fortunately, they are huge bang for buck in my system and 2 dozen cost way less than a Silver Tellus, and they had a really nice positive impact. I did not put them near my network boxes...but even on my Wilsons, the exposed cables that connect the modules benefited from them. quieter and further reduction in 'artifice' that I think comes from emi/refi/distortion generally.

 

[spiritofmusic]

Terribly sorry to contribute to you emptying your bank account further by suggesting grounding to you, Christian . As for me, I'm drawing the line by not going to the Atlantis box/Apollo to Atlantis leads. I actually got less than decisive results w/my Atlantis box trial, but proceeded to dust down my $8k Burmester 948 (that I was actually prepping to sell on!), and the synergy w/Entreq and balanced power has been a massive bonus. I'm curious to see how grounding the mains via Cleanus checks out (this will be approx the cost of an Atlantis add-on box).
I'm about to pull my cheque book out and plump for a top of the range Symposium Acoustics Isis 4 tier rack w/all components Rollerblocked, allowing me to site Entreq and transformer on my current mid level Isis rack. Hoping like the positive Stillpoints/Entreq comments here to gain further performance impvts.

Tell me about it!
As we both know the really big improvement comes from the Silver Tellus/earth leads. Stillpointing the Silver Tellus doesn't produce anything like the same magnitude of improvement and can come at a later stage. Speakers and source components are the priorities for Stillpoints in my experience.
