The QR/BB device in Everest is (IIRC) 3X larger than Denali.

Connecting a chassis ground cable from your components to the GP-NR terminal is not required, but connecting one, ideally to an external ground terminal on the component chassis, to one of the GP-NR ground posts of a Shunyata power distributor (its on all models save the PS10) will notably reduce ground-plane noise.

Reason I mentioned using the ground cable and connecting to the GP-NR terminal, is that it's another significant feature that helps to reduce ground-plane noise but often times, customers never bother to use it. And...they should.

Here's a pic showing the four ground terminals on the back of Everest. You can bet, knowing how thorough Caelin of Shunyata is...they're there for a reason. My advice is...use them. Your system will sound better.



Here a chassis ground terminal next to the RJ45 port is shown on a Lumin U1, for example (note it's labeled "Earth Ground")



Many of the other Asian audio companies are very good about installing a dedicated chassis/earth ground terminal, but American companies...er, um, not so much.

However, John Swenson, good engineer that he is, even put one on EtherREGEN. And...it makes a notable improvement when you connect a ground cable from it to a Shunyata GP-NR system. John's an excellent engineer, and understands the benefit of doing this.



Here's mine, connected with a Shunyata Venom CGC (chassis ground cable).


Even connecting this cable ground cable from ER to the GP-NR post on my Everest provided a notable improvement.

If a dedicated chassis ground terminal is not available, and there is a chassis fastener, e.g. a bolt or screw, that connects to chassis ground (aka "earth") you can connect to that chassis screw or fastener with a ground cable with a spade on the end, and a spade or banana on the end that connects to the GP-NR ground post of the power distributor.

In this application, for safety reasons, you must check connection to chassis ground using the ohm meter function of a multimeter. The best way to do this is to put one probe of an ohm meter on to the chassis fastener you may want to use, and the other probe on to the ground pin of the IEC receptacle on the component (where the power cord is plugged in). If the ohm meter reads zero or very close to zero, this indicates this chassis fastener connects to chassis ground.

You can order ground cables from Shunyata in range of models and lengths. Just talk to MasterLu, he'll set you up.
