Entreq Ground Boxes & Cables

After a solid week in the system, the Entreq is staying. No doubt about it. More resolution, more detail, blacker backgrounds, more alive.

Not a surprise as I told you they are very worth it. Had a S. Tellus with Atlantis and upgraded to Olympus Tellus for the best.
Apollo cables are the most universal of the line. Atlantis are better in some system but can be over detailed in some others. They are more specific.
I can't wait to try Everest in my system but PO is very busy man. A gentleman farmer in fact.
Jazzhead I didn't understand how you connected the negavitve output amps : did you connected both the Poseidon And the Olympus minis ? Please explain.
 
I've got a couple of weeks on my Entreq now and I have to say, it's definitely not leaving. More harmonic richness. Lower noise floor. More detail and resolution, without harshness.

With horns they are already at 12 (out of 10). I don't notice any increase.

Now THAT is interesting. I have never heard any of these devices that initially seemed to smooth out the sound that didn't impact the dynamics on further listening....

I personally have not noticed any decrease in dynamics in my system as a result of the Entreq boxes. And recently, I had the pleasure of listening to one of the most realistic systems I have ever heard anywhere. That system used Entreq boxes for the front end, and it had extraordinarily real scale and dynamics.

Of course, that doesn't mean that Entreq boxes will not reduce dynamics in some systems. But in my admittedly limited experience, that hasn't been the case. Bottom line: worth trying them out with a no-obligation trial.

When listening, I do not ground my system at all. It's been many years (maybe 35?) since I have done so.

I always appreciate the enhanced purity and musical flow.

Especially at audio shows.

I leave one item - in my case these days, the ASR line stage battery power supply - grounded until I am about to listen, then I simply unplug it from the wall.

All of my power cables (except the ASR line stage battery power supply) do not have the ground pins, as I removed them as soon I decided that I wanted them.

Any grounding schemes I have tried have always resulted in significantly less interesting sound. Maybe the Entreq is the antithesis to my theory. It's certainly got to be less risky...

In fact, I do NOT recommend such a practice for others.

I would love to be able to ground my components without compromising the musical engagement factor...

Jim,

i wasn't aware that the battery PSU could be unplugged for listening pleasure. Do you do this at home too, or just at shows? Big/small difference IYO?

Thanks!

Steve

Jim,

The Entreq grounding boxes have nothing to do with "safety AC grounding," they connect to "signal ground."

As I'm sure you know, in some components signal ground is connected to safety AC grounding, and is easy to determine with a multi-meter.

When I tried a Silver Tellus and Apollo cables in my system, with the cables connected to signal grounds on my amp and source components there was no improvement.

I didn't try them on my amp or speakers negative terminals like Mike, so maybe they're worth a try.

I did laugh when I read about their new K2 and Everest attachment modules,
which replace the stock wooden binding post nuts. Before spending $249. or $349. on these, I'd go to my local hardware store and buy some copper or brass nuts that fit the binding posts.

Thanks! Frankly, I was unaware of how they worked so I probably should have kept quiet.
 
Another endorsement of Entreq grounding boxes. My tube power amp and tube preamp are connected to a Poseiden via Apollo cables. What I have heard in my system is a larger & fuller soundstage, more tonal colour and a more engaging sound - with no loss of dynamics. I consider the money well spent.

Agreed. I haven't taken mine out of the system.
 
Reading through this thread, there seems to be confusion as to using Entreq with Vitus, as far as I know Vitus owners are using Entreq without problems? Can somebody clear this up.

My own experience with using Entreq on a one day trial, was very positive. We started at the digital end with a Olympus Maximus connected to the fidata server and then went through upgrading the cables. Every stage was a positive. Moving to the Tallus 2 was slightly better I think, but I need to double check this? We then introduced the Poseidon, connecting the Mola Mola pre/dac to the centre post and the negative amp terminals separately to the two outer terminals. All the positive aspects of a clean back ground, more space around the instruments, more natural top end, better bass definition, were intensified with this set up. Highly recommended.

PS Should add that the Everest’s had a positive result as well.

Is there any continuity between the three terminals?
 
If the three terminals are all independent, then it will be safe. Just like connecting 3 independent insulated wires. Although some audiophiles call that 'Groundside Electronics'. All a wire connected at only one end can do is act as an antenna.
 
What they tell you from Vitus, is exactly like what the Constellation technical service told me: If I plugged the negative terminals of my amplifier into two Silver Minimus boxes, the amplifier, "kaputt".
Frankly I did not understand it, but I still did not dare. Until a guy from WBF sent a picture of his stereo Centaur, with the terminals connected to two Silver Minimus boxes, then I decided to do it. And ... nothing happened. Well, something happened, my system sounded better. Many manufacturers hear the word Earth, and they no longer want to hear anything more than you explain, say NO.
On the other hand I have to say that in my experience with Entreq boxes, the connection of these to free signal outputs (RCA, XLR, USB, RJ45), has always improved the sound. However, this has not been the case when I have connected the chassis ground terminals (on those devices that have them).
