Entreq and Innuos?

@nyev I have my Zenith and PhoenixUSB fed from my Isotek Sirius. The Sirius improves the sound for sure, but perhaps now a little too bright. Am I right in understanding that your system is better with the PhoenixUSB fed direct from the mains, while the others are best from the conditioner?

I’m tempted to try an earthing solution, but not sure how Entreq would work with the Phoenix as it doesn’t have any spare sockets. The Zenith is a better option.

To answer your question: Entreq with each earthing box supply a single connecting cable and a single plug, which you can select from a choice:  RCA, XLR, USB, RJ45 etc.  They claim that any one of these plugged into your unit will satisfactorily ground it.  So, we should be able to ground the Zenith by (eg) the Streamer RJ45 socket. 

I do wonder if taking an Entreq plug of some form, plugging it into a spare socket of my Zenith, then connecting it to a metal spike sunk into the ground would work. This is what, as far as I understand, the Entreq boxes simulate but without the risk. It should, I think, offer a preferable and benign route to ground for stray micro currents in the boxes, rather than the house’s protective ground.

@nyev Is there any chance you could resurrect the chat with Nuno and ask him how the Phoenix could be grounded? 

@nyev Now that the Xmas break is over, I'm looking at this again.  

Russ Andrews offers a very affordable grounding solution.  Details are here.

I'll give it a go, starting off with the casework of my three Innuos and Hegel boxes.  As far as I can tell the casework screws on the Phoenix are already grounded, so assume the entire case is.  However, running a continuity test across the USB sockets' earth pins and the IEC earth pin produces a fail. The Zenith is grounded via the USB/Ethernet socket casings, plus the screw top centre at the case's rear.

Compare that to my Hegel H390, the continuity test passes when testing across the IEC earth pin and the outer casings of the BNC and RCA sockets, as well as the earth pin of the XLRs.

It's interesting that Russ Andrews advocates wiring his grounding box to a copper spike stuck in the ground. This is legal here in the UK. Obviously, it's not an alternative to the safety earthing of the system, which will remain in place.

@ozzy I've just noticed your mention of the Russ Andrews unit.  I have the RF Router mk2 on order, plus cabling.

Can I ask if you're using the basic cabling, or the Technical Ground Weave?  Also, have you connected the output cable to the mains earth, or an external ground rod?

Thanks very much.
