I recently bought an Acrolink 7N with the Oyaide P-/C-004 connectors and find them to be quite neutral. With the Acrolink 7N what you're basically "hearing" is the connectors much more so than the power cable itself. I have the same P-/C-004 connectors on the Acrolink 6N cable and find it a little warmer sounding and not quite as good at disappearing.
One point to keep in mind regarding my comments, I'm using Oyaide's R-1 outlets so there may be some synergy going on with the connectors since they follow the same plating structure of palladium over platinum over beryllium copper.
