I have purchased my first component of a soon to be home theater system...Denon AVR-3802. I would like to purchase a pair of headphones that will best fit my needs. I have read through many posts here and the links I have seen posted as well and still have not come to a conclusion. I will be listening to movies mostly. I read alot of people mentioning that certain headphones need an amplifier. Does the AVR-3802 have a sufficiant amplifier to run the Sennheiser HD 580's? And I hardly see any reviews or post's reguarding the Denon AHD-950. I am not worried about if it is an open or closed ear, unless it makes a difference in how the movies sound. I will be in a quiet room. Any help would be appreciated.
