Unpacking the Shunyata Everest 8000

The ground terminals on the back of our power conditioners are primarily designed so that you can connect multiple power conditioners to each other. This provides a common ground which reduces the possibility of ground loops between different AC line sources. They also allow you to connect the chassis ground of the amplifier(s) which are usually on a separate AC line to the power conditioner ground. This provides a "common ground" for all components in the system that may not necessarily be powered from the power conditioner.

The GP-NR does that and more. It actually reduces noise on the ground plane internally within the Everest. And the four ground terminals on the back of the unit allow you to connect your audio component chassis' grounds to this ground noise reduction system.

Even though it is true that the power cord provides a ground connection to each component through the power conditioner, external and separate ground cables connected to the Everest GP-NR system can improve performance. This has several reasons. First the separate ground wires are not in close proximity to the HOT and NEUTRAL wire within the power cable. The ground in the power cable is subject to inductive and capacitive coupling of noise. And a secondary ground provides an individual ground wire reducing the total impedance to earth for each component. This can also help reduce small amounts of hum and residual noise.

In some cases, the effect is minor but in others it can be quite dramatic. And as the OP about GP-NR noted that the sound quality can be improved.

My best advice — if you have an Everest — try using the GP-NR and listen to the result. Then, experiment with better quality ground cables. This should be fun, not so serious. Let's have fun with it.
 
I've used CGS10 cables since Triton V2 and they've made a positive impact ever since. I have 2 Sigma CGC's coming soon hopefully. I thought the Sigma V2 CGC was getting the TAP device but it seems it was scrapped?

I may be wrong, and Caelin should jump in here, but I'm not sure a TAP device would be necessary or provide any function for a grounding cable because it does not carry signal, as an interconnect does.
 
The previous CGC generation had a TAP on the Sigma CGC according to spec if I read correctly. Hopefully an Ohm.. version will manifest with everything we need. :)

Meanwhile the Sigma CGC is truly awesome. I put it on my Etherregen GND terminal into a Denali 6000/T. The whole sound scaled and grew more powerful. Then came the Alpha V2 clock 75 to my OCXO and you can sift through the recording venues air vibrations with your hand now. :D
 
Sounds like a good idea, yes. I am using one Sigma grounding cable for my Devialet D250 with great result - would be fantastic if a second cable bring a similar benefit.

A note about the current CGC cables, I think only the Sigma contains the V2 Cu/Ag configuration.
 
Can someone chime in on the small LED lights in the bottom front of the Everest? There are two, the one on top is lit blue(ish), there is no light at the bottom one. Normal?
 
One of the things I like about the LED on Everest is that it is just bright enough to know the device is on, but it is not obtrusive in any way. I wish I could say that for the blue LEDs on my other devices. The EAR 324 and First Sound preamp LEDs are brighter but not egregious; the LED on Keces P3 linear power supply is, I would estimate, ~20X brighter than the LED on Everest.

This is one of things I really like about Shunyata's products; they think things fully through, down to the smallest details; for example, the vibration damping that is also built into Everest and the V2 series of power cords.
 
Hmmm....I'll have to pick up a Shunyata CGC to connect to my EtherREGEN, then. Thanks for the tip...

I have also deployed some between my 2 Devialet and other key components to the Everest. I think it makes a difference. ;)

Cheers,
Bernard

If those components are plugged into the Everest, and they have proper ground pins, why do you have to “ground” them to the Everest via that grounding cable?
