Given system variables, I understand that this may not be an easy question to answer, but in looking ahead to my post-Christmas break-in to my penny jar (I like to plan ahead), which option is likely to improve sonic performance more in the bedroom system detailed in my signature block--an Altaira chassis hub with Venom v3 ground cables or an Alpha NR v.2 PC for my c-j Premier 17LS line stage (currently fed by a Delta NR v2)?

I ask because replacing the Delta XC v2 with an Alpha XC v2 to feed my Delta D6 power distributor has effected a significant improvement in perceptible resolution, soundstage dimensionality, and transient quickness. My first thought was to consider an Alpha NR to feed the c-j line stage currently fed by a Delta NR. But seeing the Altaira video and reading commentary on the unit suggests that my pennies might be better spent on dealing with system grounding.

Note that none of my source components has a dedicated ground terminal, but each has at least one spare set of RCA input jacks available, so I'd ground-connect via that route. The amp has neither a ground terminal nor a spare set of jacks, so I'd have to find a chassis screw that would provide an actual ground connection.

Your thoughts and advice appreciated.

TIA.
