hi Ade,
no need to put off the upgrade in my opinion...I'm watching Sherlock Holmes on DVD through the Caiman just now and it sounds fantastic..
With music...no sign of the brightness others have spoke about here, all the top end stuff like cymbals, drum thwacks all sound very very clear with weight but smooth and not harsh in any way.
What I'm loving the most is all the subtle stuff that's coming through..fantastic stuff.
