Connecting Ground Connectors (Torus and Gryphon Diablo 300)?


I have a potential minor issue with separate grounds between my two dedicated AC circuits. My 3 Innuos digital boxes are plugged into my Torus RM20 isolation transformer which is plugged into one dedicated circuit, and my Diablo 300 amp with DAC module is plugged directly into a second dedicated circuit. For some reason my Innuos reclocker sounds better when not plugged into the Torus like my other two Innuos boxes are. Innuos says this could be due to the grounds being different and suggested I try some ground boxes.

But my Diablo and Torus both have ground terminals. Would the simplest approach be to just get a cable that connects the ground terminals of my Torus and Diablo? If so what type of cable do I need?

I’ve never messed with ground terminal connections before so I don’t have a clue!

How would you describe the difference in sound, with or without the Torus?

@dpop , when the reclocker is connected to the Torus, the sound becomes less weighty with less bass, there is less dynamics, scale, and drama to the sound, and there is less air around instruments and vocals with not as deep of a soundstage.  Midrange tones and vocals are a bit louder and have a more forward presentation.

My other Innuos devices prefer to be connected to the Torus.  In fact my Zenith mk3 streamer server sounds thinner connected to the wall.

Thanks for the additional info. I don’t think this is a ground issue. Ground issue problems are normally hums and buzzes. It’s *very possible* that the reclocker is producing more correct tonality when plugged into the Torus, but no one can really say for sure, but since you can tell the difference in sound between it being plugged into the Torus, and not being plugged into the Torus, why not just go with what is more pleasing to you (I realize it’s a stupid silly answer to a more complex question)? Unfortunately I don’t think I’m going to be able to give you any kind of scientific reason why the difference in sound is taking place.

You could always give this a try if you wanted to. You’re technically not grounding the units (as they are already grounded when plugging into the wall outlet), but instead you are "bonding" them. Any 18-14 AWG wire would work for this. Believe it or not, many electrician’s many times confuse the terms bonding and grounding. Come to think of it, I rarely see the term bonding mentioned on this board.

Sorry I couldn’t help more.

Thanks @dpop. While tonality is one aspect that changes, other differences include better dynamics, and a deeper soundstage with more air. I wouldn’t think that less dynamics and and shallower soundstage would be more “correct”, but who knows.

The reason I want to solve this is that I want to replace my Innuos Zenith Mk3 streamer/server and PhoenixUSB Reclocker with Innuos’ new Pulsar which is a pure streamer that includes a reclocker. Innuos tells me this will be better than what I have now.

My “workaround” won’t be possible with a one box solution.

So, I’m trying to figure out how to connect the ground terminals of my Torus and Diablo amplifier. It may not be the solution, but at least it’s something to try. I’ve heard ground issues cause hum from the looping that can happen. But I’ve also heard from a few reliable sources that establishing common grounds can improve the sound.

I’ll give the “bonding” approach a try, just because.  Thanks!
