Kanuk,
I use the DIP with a standard panasionic DVD s 52 and the DIP made a significant increase in stage depth and instrumentation seperation. However you also need to use some pretty good digital interconects with the DIP. I have found that the Stereovox interconnect works well with the DIP. The DIP does give better sound if you use vibration control products (I use mapleshade stuff) and it makes a small improvement over just placing the DIP on a hard surface.Hope this helps.
