Could anyone help me with this one? I have a 3-yr old SKY digibox linked to a Panasonic 4 plasma via a Lumagen scaler. The box is the basic default Amstrad model (the 100 I think). My question is: do the various digiboxes (Sony, Panasonic, Grundig) give essentially the same picture quality? I know some are faster than others, and others have lower threshold signals, but I really want to know if I can improve the PQ by changing box since a few of these come up on the classifieds at fairly reasonable prices. The present PQ is good but if I can improve it further I would of course do it. Any advice appreciated!
