Yes, I so much do like the robust DVI connector that I am sorry they didn't stick with it when they decided to include audio and came up with HDMI. My own NEC 50XM5 Plasma monitor has no speakers so I am not at all interested in a cable to it that includes audio, anyway.
Winston, I would suspect that any improvement you might somehow find in a cable will be defeated by using adaptors as they will weaken the signal.
"The more stuff along the way, the more there is to contend with."
I can tell you that my own picture quality does improve a bit when I went from a Radio Shack Gold DVI/HDMI to a Varastarr cable with the same terminations.
