If folks get a CG hub first to use with a "basic" core system, they can always add an SG hub later to develop a "segmented" system. And, they'll get improved performance compared to using just a single CG Altaira. But, they'll get even more performance when both hubs are SG hubs when implementing a "fully segmented" system.

And, that's what I'm doing, specifically. I have one dedicated SG Altaira hub connected to the Lumin P1's external ground terminal and it's S/PDIF interface, and another SG hub for the CJ LP70S power amp and phono stage's ground terminal as the "analog" stack. I actually installed a banana plug-style ground terminal on the back of the LP70S to connect it to Altaira. Every "place" (component, "piece of gear", switch, etc.) that's powered where you can lower ground-plane noise pays dividends.

Back when my EtherREGEN and the Lampizator DAC was in the main rack, ER's ground terminal and the Lampi's S/PDIF interface was connected to the "digital stack" SG hub. I noted that Lukasz installed a dedicated chassis ground terminal on the new Horizon DAC.

The other place one would benefit from installing an SG Altaira hub would be if you have a remote server room or closet, with a music server or Roon Core, NAS, router, switch, master clock, or FMCs, for example.
