Taking one for the team Jeremy. We salute you!
There is a feeling of accomplishment that comes with taking on projects like this, but had I thought of doing it earlier in the year, the warmer and drier summer conditions might have been a better time to do it
Looks like Nobel prize winning work, Jeremy!
You get my vote
I have a Rossini Apex. I have its power cord plugged into a Shunyata Everest (Sigma cord). I also have it connected to a Shunyata Altaira (sigma ground cord). I noticed a significant improvement with each (power cord and ground) especially the power cord. I now have everything connected to the Altaira and Everest-- amp, preamp, Rossini. There is definite improvement in terms of noise and hence clarity in the musical presentation. I do not know for sure, but suspect having a common ground may be part of the improvement.
While I struggle to get my head around why grounding box A might be different from/better than grounding box B (living and learning!) there appears to be a sound logic to grounding all your stuff to a single reference point. Thanks for reporting back.
With my own grounding, I’m currently battling with the thought that a ground wire could fast become an antenna and the way to deal with this would be to shield the ground wire, but that seems to lead to the question how do you ground the shield for a ground wire?!
A shield passes the noise it has picked up to ground. A ground wire also passes noise to ground.If so then a ground wire cannot act as an antenna as any induced noise is also passed to ground. However others are better qualified than I.
Haha, stop giving me ideas for my next start-up!
Ah, you need to shield the shield… and then shield the shield of the shield…
I’m not sure there is any role for shielding in this application. The shield will just act as another grounding connection. I still might make up a shielded one to see if it looks nice… and will give it a listen but have no expectations. I always try to understand the underlying mech and here I can’t envisage what that might be.
This!
I think the issue is that wire has an inductance and the induced current passes down the wire at a finite speed, so the potential is only zero at the point the terminal is grounded, the other end of the wire can be at a higher potential.
I was wondering about star earthing the shield and ground wire. My concern with that approach is that the earth has an impedance somewhat higher than any connection between shield and the ground wire…
Hi Jeremy, with all respect I think you are getting a bit lost trying to apply basic electrical theory when to understand how an antenna behaves you should be applying basic antenna theory. A ground rod actually makes a pretty poor ground for an RF antenna, I don’t think you need to worry about this.
I completely agree - and thank you for the link
Just an addition with my experiences regarding the Shunyata Altaira Chassis. Shunyata recommends connecting the Altaira to the Denali 6000S v2, which I own. So it was done in no time. After a long time I started thinking…(headache?) What would happen if I connected the Altaira directly to the ground of the AC socket with ground, so not via the Denali? It didn’t take me long to hear that it sounds better (more open and direct) and to clear all doubts, I tested this more than once. Wasn’t actually necessary because it’s just better (in my situation of course). I would say to those who also have an Altaira to give it a try.
@craigr This week i also did the grounding of my system with the Nordost with the QKore 6 and i also notice a big improvement.
Hi Friends,
Well, I can now chime in with some first hand experience, since I started this post.
I have been using a Synergistic Galileo SX Ground Block Mk 2 (with foundation cables) in my home system and have heard the Shunyata Altaria on a friend of a friend’s system.
Altaria …. since I only heard it once (on an unfamiliar system) I can only briefly comment. For me, it was very subtle, a slight decrease in background noise, along with slightly improved clarity but I had to listen closely in an A/B comparison.
Synergistic …… I’ve been listening for about 10 days (small sample time) and have done more A/B comparisons than I want to admit to. When comparing, I didn’t just turn off the active Galileo unit but also disconnected all grounding cables. With the Synergistic engaged, I heard greater air around the notes, slightly more attack, decreased noise and a a brighter high end. All this was once again subtle, (not night and day difference) but noticeable, none the less. It brought out slightly more of that musical ‘realism’ we all seek. I think I will buy the Synergistic system.
Interestingly, with the Synergistic engaged I liked filter #4 on my Rossini more than the Filter #1 which was my go to.
Anyway, just my limited impressions.
Thanks again to all those who contributed (and hopefully all those who will continue to contribute).

Just one more positive comment. Too bad you haven’t tried the Altaira at home. Only then can you make a real A/B comparison. My experience with grounding is also that you only hear the maximum result after a few days of no changes. I have also tried various cables. I took apart a Neotech 3001 power cable and used the loose wires as ground cables. A very thick cable with the purest copper. Nice addition, it doesn’t cost much to try.
