Why the Distain For the Rotel RB-1080 Power Amp?

As a newbie doing the research to assemble a solid 2 channel system, I am winding my way through the myriad of choices in the preamp & power amp market. A daunting task. In the process, I have come across many audiophiles who feel that within the same price range there are many preferable power amps to the Rotel RB-1080. Is there any objective basis in this broad statement or is it simply the "Ford vs. Chevy" debate in sonic clothing?
