"• Lower perceived background noise."
Does not say that it actually lowers the background noise, just the "perceived" background noise.
So measured reality or placebo effect?
Next statement seems more definite:
"• Deeper, more dimensional and more vibrant picture on AV systems."
OK how about some real measurements to prove that statement then? How do you measure deeper, dimensional and vibrancy (or is it black level, resolution and contrast.... mostly properties of your display)
