I know this question has been asked in this forum in different forms, but I am trying to compare these two projectors. I am setting up my first dedicated home theater room and have ordered the Domino 30H from my dealer. Recently, he said that he had a HT300 XTRA H available that has 21 hours on the lamp. He is asking a price difference of $1200 US dollars. Will I see a definite difference in picture quality between these two projectors? I will be using a Denon 3805 & Denon 3910. Thanks for you reply in advance.
