FYI, I emailed Don of DCCA last week; I'm still waiting for a response. :-(
I emailed Virtual Dynamics Tuesday and received a response yesterday. They no longer sell the Nite 2 cable, as I suspected, but say that the Nite 3s are an improvement over the Nite 2s all across the board. They are (currently) just slightly above my price range, but I may try a Nite 3 anyway. I have yet to find any used Nite 2s for sale.
Received my Black Sand cables yesterday and will be getting my VH Audio Flavor 4 cable on Friday. I am still going to buy one or two more power cables - guess I'm on a roll and really want to find out if I can detect a difference between PCs in my system/s. So far I have heard no remarkable change using a Black Sand violet on my Consonance Droplet, but this is after only a couple of CDs - way too soon to make a decision. I will be able to A/B the Black Sand and the Flavor 4 this weekend, if I don't spend too much time at RMAF! :-D
