Solid wire Stephen?
Sure, that will work. I used stranded wire, but solid wire will work, too. The most important attribute for grounding applications is impedance, so any quality or design that will reduce impedance will be beneficial. Obviously, larger gauge will have lower impedance than a smaller gauge wire. This is why the Alpha cables sound better than the Venom/Delta and why Omega sounds better than Alpha (though the CMode filter helps, too.) The Shunyata ground cables are stranded, not solid wire, FWIW.

If you segment a system, where you would connect a DAC, to the Altaira SGC where they are connected is the Server, the Switch and the Router or the Altaira SGC where the amplifier and preamplifier are connected.
Try it both ways and go with what set-up sounds best in your system. Either approach is valid, so let your ears be your guide. When I had my Lampizator, I was connecting ER and the Lampi to one SG Altaira, and the pre, phono stage and amp to the other SG Altaira hub.

I was reading Jaccob Heilbrunn review of the CAD ground boxes. He noted some of the dynamic wallop was muted.
Has anyone listened to their Altaira with a focus on dynamics?

As I indicated, I recently heard the Altira at Robert Harley's. In his system and inserting my WestminsterLabs amplifiers there was no diminution of dynamic wallop and an immediate overall improvement of making everything our amplifiers are known for "more better". I would surmise there may be different/better results from considerably more expensive grounding solutions ala CAD, Entreq others, however, I am now convinced that in most systems having an effective chassis ground escape path will make a considerable difference for the better. I am hoping to have a Shunyata for testing in my system in the near future and will report back.

Note:
RH's current speakers under review from Wilson Benesch with matching subs will not match the dynamic wallop of his mighty Wilson Whamm Master Chronosonic and matching subwoofers, so in that system his conclusion is entirely feasible.

Absolutely, yes. I have two signal grounding zones via two Altaira SG Hubs. The Altaira have no negative impact on dynamics at all; in fact between the SG hubs and moving up from the Triton v3 and Typhon QR combo I'd been running for almost 5 years, to an Everest 8000 in general and specific to the improved chassis grounding plane and filters in the Everest, dynamics and overall capabilities of my system have improved drammatically.

I have three Altaira Signal Grounds in my system and there have been zero drawbacks.
The three foundational pillars for a world-class system are: Power / Grounding / Vibration.

How have they changed the sound of your system? In what sonic ways, specifically?

Thank you.

Here are the listening notes I made when I first connected the Signal Hub (note that break-in is ~250 hours):
  • Listening notes:
    • More high end detail: Manha de Carnival Dexter Gordon Montmartre 1964. Cymbals were hidden before!
    • Better localization (Sounds of Movies, which was never top notch in this regard)
    • Newport 1958 (Remastered): big difference! Clarity, localization
    • More authority and presence! Especially in the higher frequencies, upper midrange
    • Lights of Barcelona - wow! More “energy”
    • Norah J: Nightingale - high hats were obscured! Never heard them before!
    • Bach - less bow wander between channels! Basically perfect.
    • More “musical”, less analytical. And there were definitely high frequencies that were completely inaudible before!
The Altaira is a huge upgrade. And my house is under 10 years old with new wiring.

I do not want to misinterpret you, but when I read "high end detail" "clarity" "higher frequencies" "upper midrange" "cymbals and high hats no longer obscured" "more energy" it sounds like a presence region or high frequency emphasis?

I wouldn’t say “emphasis”; but I can see why one might interpret that. I would say more “revealing” in the high frequencies- there were cymbals for example which were not as noticeable before.
There is also a greater sense of overall “energy” across all frequencies.
I agreed with the Absolute Sound(?) review as well.
If you have an Denali or Everest already, adding the Altaira is a no brainer, in my opinion. I think a retailer will take it back if you’re not satisfied.

I wonder how the isolation transformers play in. Jacob has and Equitech. They add dynamics and life. SC and Zei do not. Whats the impact.

And another review where for the same reason someone liked the Puritan grounding system over the CAD.

Really wonder how the Puritan stacks up against the Altaira.

What is “SC”and “Zei”?
SCAudiophile and Zeotrope. Neither have an isolation transformer. I have mentioned Shunyata has a dedicated transformer that isolates their listening room. What is that doing to the performance of anything they make. Just asking the question. I have never measured.

Yup. BIngo. The high frequencies have improved clarity and extension, but not at the expense of "naturalness". The presentation has more "information", yet is more "relaxed" as Hans Beekhuizen says.

Read Harley's review in TAS. I think it's safe to say, and I'd predict the other Altaira owners would agree, it's not quite like anything you've experienced before. And once you experience it, there's no frickin' way you're ever gonna go back.

Yeah, it's got virtually nothing to do with the wiring in your home....
