John, Thanks for the response. Sounds like the CSP is likely the best direction for me, as I thought. On the separate supply question, it would be great to have that option... and I am not above hacking a board to make separate power inputs... did this to the ESI Juli@ card I use on my current computer music setup. BTW, it was my experience with powering this card separate from the remainder of the computer that had me build multiple separate supplies for the components in my computer audio setup, with good sonic effect. OTOH, I remember how you described the effort you are putting into the grounds and multiple regulators on the CSP and I suspect it will exhibit less improvement with separate supplies than many other mixed-realm setups. Finally, since no one else seems to have asked recently, are you getting to a point where the cost to buy a CSP (board only, already have the Wandboard and case) can be estimated? I see that the expected price of the Bottlehead DAC is pushing $1000... where might the CSP range? TIA!
