Nordost QKore grounding unit

Granite Audio, essentially same approach as Nordost. $550 incl. 6 grounding cables.

This is really cool: They are referencing CES 2004 on their website. And yes, even audio pros using their product at the show [emoji3].

I know Synergistic Research has grounding block starting at around $600 for the passive one all the way up to $3300 for the active SE model.

Thanks, yes have read about those as well.

You can also use the Ansuz distribution blocks (A2,C2,D2 and DTC) with Ansuz powercords, they rely on very good grounding, all the Ansuz powercables have a 10mm earth lead inside !
No extra boxes needed this way.

At least all EU Schucko cables do have grounding by legal regulation. That’s a different thing.

Stereophile’s JVS appears to be quite convinced about this thing. It’s just hugely expensive for a completely passive unit.

Anyone using it? Are there other comparable alternatives for a bit more reasonable amounts of money?

We've got on tests QKORE6 with QBASE QB8 & TYR2 and results are just amazing. Better resolution, wider and deeper soundstage - much more air around musicians without loss of weight.

Thank you Marcin for sharing your experiences.

I have actually heard a QKORE in vs. QKORE out demo and quite liked what I heard.

Just looking for alternatives due to the IMHO bloated pricing [emoji3]. For 3K I would buy the QKORE6 in a heartbeat.

$10 alternative:

May actually work even better, due to larger openings for bigger wires (bigger wire = lower resistance = better grounding).

IMO the biggest problem with the devices from Nordost, Synergistic etc. is the tiny wires they use.

Interesting [emoji3].

I was actually considering something similar. Why not just take some heavy metal lump (e.g. aluminum or copper) and drill some holes in it. Then connect copper wires from it to idle component RCA inputs to address the issue.

And what about active grounding boxes (such as the Synergistic Research Active Grounding SE, I think). Don’t you think having the grounding device connected to your main electricity system would be beneficial (to equalize the load)?

I've spoken with people knowledgable with grounding, and none of them had any idea what 'active grounding' actually is, and how it is supposed to work :) IMO this is just another audiophile snake oil.

And speaking of grounding cables - those are a 'proper' grouding cables (braids):

Interesting. I don’t know either, which is the reason why I am asking [emoji3].

So how would you attach those braids to components? And would you connect them to e.g. unused RCA inputs or just the chassis? Would that make a difference?

Please apologize my many questions, but I am eager to understand the topic better.

Car audio stuff is ideal for this.

Go to any car audio online shop to buy the power cables (they come in many guages, even thick as a finger ones; IMO 4 or 8 guage would be ideal), the power block I mentioned and all connectors needed.

Personally, I would use eyelet connectors and would attach them using the crimping tool to equipment end of the cable. Eyelet connectors can be easily attached to any component chassis screw.

On the opposite end, you can attach the power cable that goes out from the power block to any AC plug (to ground terminal). Just get a heavy duty AC plug so that a thick wire would fit.

There is another elegant solution:

Not as good as the one I've mentioned, but very easy to implement and ... well, elegant.

You would only need to change the equipment cable ends to a crimped eyelet connectors.

This is similar to what I found in a description how they grounded all equipment in a recording studio.
