That is possible for sure.
I do know that I can generally tell the difference between higher a lower quality BR players, even on the 42 incher. Just when it comes to the HRs, I can tell no difference. That leads me to believe that even IF there is a difference, it is so small that 99.9% of people will not notice it.
I may take the 23 up to my uncles and hook it up to that 120" (I think thats what it is) projection screen. He has a 20 I know, so I should be able to do a side by side quite easily.
that's a great idea. curious to know what you'll see.
