I added the Nordost QKore Grounding System to my system at home today. Damn, it works. I hate the voodoo….but it works.

I listened for an hour and then hooked it up and played the same songs. I heard greater micro detail retrieval, better bass, better controlled sibilance and a much more relaxed presentation.

I hooked up the 552 preamp, NDX 2 DAC and N20. The amps don’t have anywhere to connect a SIGNAL ground cable. It needs to be something like an unused RCA input/output, unused XLR input/output, unused SPDIF/BNC connection, that sort of thing.

The grounding unit (QKore 6 in my case) is heavy as hell. It doesn’t look like much, but damn, it’s heavy as heck.

I have ordered QKore 3 and waiting to arrive. Have lots of hope based on user experience and reviews. Good to know positive experience in your system. I am planning to plug to preamp, N20 and esoteric K-01XD.

Excellent. Let us know how it sounds. Did you go for the premium ground wires?

Yes. I was originally thinking of entreq, but they are big and look like furniture. The appearance and size of qkore fits my set up.

Cool. Just remember, it’s heavy!

Did not know their weight. They look small like a internet modem. But damn good nordost for not making it bulky and big.
 
Have seen and heard at shows but never tried at home. May need to try sometime.
 
Have been using it for almost 1 year. Consider it as an indispensable tweak in my system. Addition of sort Kones underneath is also transforming.
 
How do the QKore system results differ from using the grounding terminals on a Shunyata Denali/Everest?

One is signal ground, the other is electrical grounding.

If not mistaken, qkore is signal ground. I also using the usb ground wire with Lumin X1 with good effect

very interesting.
does the q kore require a q base or would it work in conjunction with an everest or any kind of distributor as well?

Good question. The QKore comes in three sizes - 1, 3 and 6. Only the 6 can ground to the Q Bases. By grounding the QKore to a QB8 for example, you accomplish both signal common grounding and electrical common grounding while essentially grounding everything together. The QKore 6 comes with a cable to ground to the Q Bases.

At home I have the Q Kore6 with the Denali 6000sV2 and have not grounded them together. In the store, we have the QKore6 and QB8 tied together.

thx, that means it is not mandatory to ground the distibutor.
after reading some articeles i do understand it as follow:

qkore1 CAN ground the qbase,
it cant ground a component.

qkore3 cant ground the qbase,
it can ground 3 components.

qkore6 can ground the qbase
and it can ground 5 components.

actually you could plug as many components to any post but performance would decrease.
the qkore6 is inside identical to a qkore1 plus a qkore3.
either the qkore 3 or qkore6 is optimised to ground 3 components.
if you ground more than 3 components with a qkore6, then some performance gets lost.
mike, as per this logic it would probably be best to use a couple of qkore3 in your homesystem.

QB1 ground to component, not QBase,

Correct otherwise.

please check this again, it is really written everywhere that the qkore 1 is to ground the qbase and cant ground a component.

The QKORE 1 is for grounding one component like a stereo amp. QKore is for SIGNAL ground. QB for electrical ground. That’s my understanding. I guess you COULD use it to ground to a QB too.
