I have both.. I found the Nite PC to be totally different then the previous PC VD put out.. not sure.. The Signature always follewed the same path that most of the VD cables would do and that is the higher end you go the more detail you got. That was up till the Nite. The Nite introduced(in my system) more of a pleasing tonality.. Im not talking night and day(sorry for the PUN) ..however it seems to be a smoother cable the the Signature or Reference..worth the audition I say !
thanks...Matt
