I have owned several CJ and BAT preamps. (CJ PV11, PV12, Premier 14, BAT VK31 and now VK32se). I would say CJ sounded more lush, liquid midrange and warmer than the BAT. OTOH, BAT sound more dynamic, greater bass, better macro/micro and a bit of deeper soundstage. I do not know the current CJ stuffs but the VK32se is a whole new level of the beast compare to the older version.
