Chouca, until you said 26ft Audioquest at the end of your post, I was
puzzled. And, yes, there are more expensive cables than Monster.
Cable quality could make a difference depending on on what
is on either end. DVD players don't generate that much video bandwidth
and there is other gear than can generate better video and at higher rates. Also, certain
dislplays are better at discerning/displaying subtle nuances in video
than others. It's all very subjective. Everything in the path from the power socket
to your eyes (and ears) has some effect on PQ (and AQ).
