    Nordost QKore grounding unit

    Yet another step in experiment.

    A bit semi-serious, but fun. Would be interesting to see though, what Adam might find inside the QKore housings.

    Dis-assembly is not required. An Ohm meter is all you need.

    Nordost QKore grounding unit

    And so...


    ...the DIY grounding device sits snugly in the rack along with the Aqvox SE switch.


    Now the most important question: what do I hear? Instrument separation appears a bit better, details are easier to make out. Soundstaging is more organized. Everything sounds a bit more relaxed.

    Is it the same thing I heard in the QKore demo 1 1/2 years back? Couldn’t possibly tell, as my aural memory is not that accurate that far back. Maybe I borrow a QKore unit somewhere to do an A/B comparison.

    Verdict: I like what I’m hearing. And it looks nice, I’ll keep my €150,- QKore challenger .

    Did you try to ground the whole thing to the AC outlet ground in the wall ?

    No, I did not. It’s purely passive. The QKore is not either grounded to an AC outlet.

    And after reading the cautions on the website you sent a link to, I did not fancy to risk frying up my house, audio system and potentially everyone in the house.

    Hi Brad, the sources are really nothing special:

    - drill bits, screws, dowels, pliers and 10 AWG speaker wire from my local DIY store
    - various types of connectors, copper o-rings and sorbothane feet from Amazon
    - 5 KG copper bar from an ebay seller (also any metal trader on the web will do)

    Re: Nordost QKore grounding unit

    It’s what I would call a “Dirty Ground”, meaning simple and effective.

    Did I see a RJ45 connection? If not, consider making that cable for the AQVox SE.

    Last is to now try to encase you piece and isolate it, then put the German Crest on it and sell it for $1200 Euros.

    Nordost QKore grounding unit

    Kuoppis,

    So, regardless of what the QKore does or claims to do (even if its the same ultimate function as your DIY unit) how is your experiment considered a ground of any sort if the block of copper itself that everything is tied to (component wise) is sitting on a wood or other non conductive shelf with rubber feet isolating the block of copper and said shelf and has no tie, conductive-cable-wise to anything else?

    Could you do the same kind of component-group-tie-down to a granite slab or a piece of Corian countertop or a slab of cork and expect different or the same results? Why is the copper block needed if it floats above ground? Isn't that called "not grounded"?

    Yes, you did indeed see an RJ45 connector.

    In one of your postings you told that you connected the Aqvox SE to the QKore, and heard an improvement. So I followed suit.

    You call this dirty ground, I call it quick & dirty ground .
