Grounding Boxes

[SOS]

I don't want to speak for Andrew but I do believe it's very system dependent. I know Andrew will say you NEVER mix signal with chassis grounding, it's either one or the other. In my system I found signal grounding to work best.

Yes, totally agree. Since I now have a new headphone amp and haven't tried grounding the chassis, it may throw up some surprises. Obviously I will change the server's signal ground to chassis also.

Here is the retail price of the Zebrano 3

SGS Products

Audio grounding box.

signalgroundsolutions.com

In US dollars it's just around $3100.

Thanks

Currently with the exchange rate the SGS Zebrano 3 is just over $3,300

I have tested with a multimeter.
The Ground chassis is the same than the ground signal.
I have tested it with my K-03Xs.
very strange.

I plan to implement the Puritan Route Master and Ground Master City.

My TW-Acustic amps only have 1 RCA connection.......from the Shindo preamp to mono amps.

Dealer suggested using an RCA cheater plug, but I'm concerned about to things:

1. Is it safe?
2. Won't I lose sound quality by not having a direct connection of my high-end Shindo Silver RCA interconnect?

Thanks for the advice.

So just hooked up the Puritan Route Master and City Master. The RCA cheater is actually a ring that goes on the amp side of the RCA connection. I didn’t think that was considered part of the “signal path” but I guess it is. I’ll report back after 20-30 hours of use.

Of course you should avoid mixing signal and chassis ground on the same box or post but I get better results with both signal and chassis grounded to separate individual boxes especially with all things digital from fmc, switch , server then dac, amp not so much.

FYI - Power conditioner and tube power supply for Modwright modified sacd player chassis grounded to one Puritan Groundmaster City; sacd player and Pathos TT signal grounded to 2nd Groundmaster City - both with Russ Andrews (Kimber) grounding cables:

As promised, I am reporting back after using the Puritan Route Master and City Master for 20-30 hours.

First I need to note that after speaking with an Entreq dealer, I moved my Silver Minimus connection from preamp to safety ground on my Torus Power Conditioner. Very nice improvement with all the things Entreq does so well.

As for the Puritan solution (signal not chassis grounding) I connected my preamp and mono amps to the Route Master and plugged the City Master into a separate dedicated outlet. The rest of my system is plugged into the Torus and that is plugged into a 2nd dedicated outlet.

Now with the Puritan in place, here are my observations:

1. grip on the soundstage (20% improvement)
2. Blacker background (20% improvement)
3. Dynamics (20% I)
4. Pace and flow of the music (30% improvement)
5. Resembles a live performance (20% improvement)
6. Tighter more pronounced base (10% improvement)
7. Overall resolution especially noticeable on vocals (20% improvement)

I happen to really like Entreq in my system and I’ve heard a “maxed out” Nordost solution on a friends all digital system.

But I must say that for $900, I’m happy with the result. Also I can’t underestimate the impact of having “both” Puritan and Entreq connected.

Hope others may find this feedback useful.

@Labpro do you have a photo of your wiring setup? So you’re using your mains ground via the house outlets, not a separate ground rod? That was one of my confusions about the Puritan GM.

Hi Keithc,

The first photo, is the City Master.

This device takes the place of a copper ground rod, and uses the ground that is already in your home or apartment building. it is said to provide 90% of the ground rod benefit without the hassle.

The second photo is the Route Master. You order the needed cables depending on your system requirements (RCA connector etc) and plug your components into the Route Master, and plug the Route Master into the City Master.

Hope this helps?

I use a solid copper bar for star grounding, with a heavy ground lead going from that to the isolated ground about 2 feet behind my stack. SMD makes cheap and effective ground blocks for car audio. In addition to good ol' fashioned proper system grounding, Shunyata's Altaire installation manual has some practical advice and recommends some tests you can do with a common multimeter to ensure that your system is grounded properly.

Thank you for sharing your impressions on Puritan GM. I am also using combination of Entreq Silver Minimus and Acoustic Revive RGC-24K in my system. Impressive results from grounding!

I use Nordost Qkore6.

Has anyone tried connecting the GM City to, say a Shunyata Everest/Denali's grounding GP-NR, similar to GM-City + PSM156? Curious if this is better than just using the GP-NR on the Shunyata products by itself.
