Nordost QKORE

Same here. Bought the qkore then within weeks the premium wires were introduced. Even my dealer was a bit perturbed as he had purchased one also with the basic wires.  I have since upgraded to two premium wires.  Also, run two of 4 premium wires to my qpoints and one premium wire from the QSource to one of my switches.

As much as I sing the praises of the QKore I do not like it with the RCA wire cable so far.

I only have a secondary SPDIF RCA input on the DAC, and another SPDIF RCA output on the Oppo player. On either I find the QKore to do little or even be a slight negative. But this is no doubt a limitation of devices available to connect it to. I have no pre-amp or integrated amp, so no unused analog RCA sockets to try it on. So the RCA cable just sits in the box for now.

Nordost has QKore USB cables, ethernet cables, XLR e.t.c So far I have not splurged the cash on trying any of these. If any of you did let us know what these connections did for you.

I have a Qkore6 also.  I use a banana-USB ground wire run to a back up USB input on my Innuos server.  I also have a banana-ethernet ground cable run to my Qnet switch.  A banana-male XLR run to an unused digital input of my DAC....All with great results.

QKore Premium wire incoming. Was supposed to get it today but delivery held back, so Monday hopefully. I only got the banana wire for connection to the QB8, so that’s the only application I can give a report on.

If the premium qkore wire is better, at least the price differential is not multiples of the tier below, as is often the case with Nordost cable tiers.

Reporting back on QKore 6. I have made a few forum posts voicing my slight disappointment with the QKore other than grounding to the QBase power distributor (where it works awesomely).

But I had limited ways to try it, only an Oppo streamer and Teddy Pardo DAC, neither of which worked well.

Now I have new kit, a Naim 272 Streamer/DAC/Pre. Lots of ports to try it. QKore did not seem to make much of a difference on the analog RCA inputs/outputs of the pre-amp section. The digital section had a BNC output, and using an adaptor, yes this made a slight improvement.

Next up the spdif digital inputs (RCA and BNC). Bingo. Here a large improvement, so much so I am buying a QKore premium wire BNC cable just to max this particular grounding connection.

My limited experience of grounding shows its system dependant. Does not work in all, or even half the cases, but when it does its huge. So experimentation is a must.
