But I want to make sure I get the best out if it and my sources. So if I start with the kit I already have which is put through the denon 3803 and upconverted / pass-thru on the component out, I assume I won't see much difference on screen in comparsion to what I have now (panny6, non-HD) ? I assume I will have to use so form of scaler (ISCAN HD / HD+ ?) to convert the component out on the AMP to a lurvley high res display ? I assume this can be done by either using the DVI (is DVI available on the PIO?) or Component out on the scaler ? Moving to a DVD player with HDMI out, I'd by pass the scaler / amp and plug directly into the plasma. But when other DVI / HDMI digital sources come along another rethink maybe in order or probably an amp with DVI / HDMI switching. I guess my question is - do I need a scaler to get the best of a HD plasma? If I go for a PIO what's the best scaler to use? Any hints / tips / ideas / pointers much appreciated! tar, Robin.
