Virtual Dynamics Nite and Nite II

Has anyone compared Virtual Dynamics original Nite powercords, IC's and/or speaker cables with the Nite II versions. I'm thinking about the upgrade, and wondering what type of improvement folks have experienced. Thanks for any and all feedback.
If your wanting to buy I have a pair of nite speaker cables 8 biwire also 2 pairs of nite 1m rca they were the last run of the nites with all the upgrades of the nite II so they are the same as the nite II. A deal on all will be 1125 shipped to you let me know.
