NBS Power Cords

Currently I am using NBS Professional PC's....I have some Master cords also. I switched the Master on my preamp to a newly aquired Pro and the difference was quite large....smoother,blacker,and the soundstage was more dilineated. My question given the performance gain jumping up a level...would going to the NBS statement PC be a good idea. I need to purchase one more NBS PC and then every piece will have Pro's on them. Just thought given the resolving abilities of my preamp the statement might be better. Anybody familar with the NBS statement and what could I expect...gains and possible negatives.

Right now my dac has a master,the transport,preamp and amplifiers have the Pro's. I would move the preamp pro to the dac and put a statement on the preamp.
