The tests for that setup here were short-lived; I did not hear a difference however, cables were short. If you are connecting the Altaira to the T2, I would leave it that way and not given worry about it at all. My current and final (what I purchased) setup is the following:
Zone 1:
Everest 8000 for my Esoteric Grandioso stack and Cybershaft master clock and Esoteric preamp with an Altaira SG-NR hub and Sigma ground cables all around for chassis ground connection to my Everest and Signal Ground connections from my components to Altaira SG hub #1. A Sigma Ground cable also connects post #7 on Altaira #1 to the Everest. Please note the Everest took the place of my Triton v3 & Typhon QR 2-box power conditioning stack that I used for over 4 years. The Everest was an audible jump over the 2-box stack and the chassis grounding alone on the Everest was markedly better than Triton v3 offered in that regard. I can only imagine adding an Altaira CG-NR to upgrade the chassis ground (beyond Everest) would be a further step up however budgets being what they are and the fact I have had to update 14+ ground cables from Delta or Alpha to Sigma after hearing what a demo Sigma could do, and buy another 7 ground cables in total for zone 1 and 2 combined, I have 24 ground cables here (chassis and signal) between 1.5m and four 6-meter, the wallet has run dry with all these upgrades.
Note that chassis ground for everything in Zone #1 is the Everest.
Zone 2:
A Typhon T2_30amp unit with 30-amp Shunyata-Amphenol twist-lock connector & large-gaude reference cable set instead of traditional power cord and IEC: this power unit filters all types of noise and also contains Shunyata's dynamic current delivery optimization. I power my Esoteric S-02 stereo amps from the duplex on the back of the T2_30amp unit. I also have a Shunyata Reference umbilical with Shunyata-Amphenol connector attached to the T2's output on the back connected to and feeding a Shunyata Venom PS8 power distributor block. The T2 through that distributor block provides power to my HDPlex LPSU and 2,250W of next-gen ICEdge amplifiers instead my Legacy Valor speakers (sub-bass, bass and SUT Array power is internal). The Esoteric S-02 stereo amps each power the midrange and top-end of the Valors. This combination of noise-filtering, differential noise-filtering, and common-mode noise-filtering (same tech as in the 20-amp Typhon T2) provides a great solution for my amps, powered speakers and LPSU. The HDPlex powers my Legacy Wavelet v2 Room Correction and Active Crossover processor.
Zone2 also has its own Altaira SG-NR hub. Post #7 is connected to the ground post on the Typhon T2 30 amp unit. The Typhon T2 ground post is then tied in to the Everest.
Note that for now, the Esoteric Amps and preamp in front of the room with the speakers are chassis ground (long cables) back to the Everest until I can afford an Altaira Chassis Ground unit. (FYI, The HDPlex and Legacy Valors have no chassis ground attach points).
This would be easier to picture with a diagram but I've not drawn one up yet. The sonic results for me have been upgraded more than I'd hoped and I am very happy. No fancy audiophile / reviewer hyperbole; the musical aspects of the system, dynamics and everything are smply much more enjoyable and great deal better.
