Hi Jason,
Yes, I'm using two Alpha ground cables with XLR tails connecting to the Inspiration's L/R XLR outputs, with each channel's Alpha cable connected to it's own "dedicated" zone on Altaira, and also two Venom RCA ground cables connected to a pair of unused L/R RCA inputs, and each of those Venom CGCs going to it's own dedicated zone on an SG Altaira, for a total of 4 connections to that Altaira. That Altaira is thus dedicated solely to the Constellation integrated, no other components, and is connected at it's 7th terminal to it's own GP-NR ground terminal on Everest using an Omega CGC cable.
Similarly, I have the Lumn P1 configured in a similar manner, with it's chassis ground terminal connecting to the "digital-dedicated" Altaira, along with a CGC connected from the S/PDIF input to that same Altaira. That "digital-dedicated" Altaira is connected at it's 7th terminal to it's own GP-NR ground terminal on Everest using an Omega CGC cable.
So, the Lumin P1 and the Constellation each have their own dedicated SG Altaira.
Ideally, though, as you've noted, if I had the budget, I'd have an SG Altaira dedicated to each channel of the Constellation. That would be the optimal set-up.
And let me tell you, connecting the Constellation to it's own dedicated Altaira takes it to another level ALTOGETHER...whoa. :celebrate008_2:
