I don't think we can be nostalgic for something that isn't really even in the grave yet... But that said, it's worth noting that while the 60 series folks seem to have some image retention complaints, I find the effect impossible to replicate on my VT50. (The one time I ever saw it was during calibration; it was the first and last time.)
There is no difference in HDMI cables. If you can see the picture without visible dropouts or sparklies, the cable is working at 100%. No other cable will display a better version of that picture. You're simply wrong if you think there is a better digital cable than one that is already working.
