I'm strongly considering this DVD changer as it will match my 2802 receiver. However there are a few questions that I have. 1) Denon mentions that there are bass management features for DVD-A on this unit. What kinds of features does this include? (ie. crossover for small speakers, adjustable crossover?) 2) Is this a good progressive scan player? (ie. chroma bug?) 3) If DVD-A goes under (hopefully not) can this unit still be used as a high quality CD changer?
