Can someone please answer the original question, I would like to make a purchase in the next few days, I am also deciding between the 2 aforementioned receivers, plus refurb denon 2805 and 3805, like the poster, price is an isssue but noit the ultimate issue. I am running boston accoustics and mirage speakers. Will the 1500 sound better than the 2400? and what are the key features the 2400 would have that the 1500 won't.
