i have had this done and you effectively get a new machine for your money. The one to go for unfortunately is the DP - �1600, this will give you DVD Audio but also progressive scan.

Ice-Age is a refernce DVD and wow the images poped out of the screen - provided your screen/projector can handle progressive.

The upsampling on DSP speakers is also staggering for movies and music alike.

yep i barked at the price but heh i didnt buy Meridian for aiwa prices so i guess the upgrade itch just gets more expensive but worth it in the end.
