I don't remember much about the filter parameters on my 800 as I went to a 900 and now to a 2000 but in my opinion, DO NOT buy the 2000. It is hardly supported (evidence right here on these forums) by Pioneer and is already outdated; big fail by Pioneer. Your best bang for your buck is the 900.
Don't think that my reply is out of frustration because of the firmware situation, if I found someone who would take my 2000 and give me a 900, I would do it in a second. The 2000 is a weak puppy compared to the 900, some people are just blinded by the many useless features and by useless I mean half complete. If Pioneer actually puts some effort in to the development of the next firmware and add/'change some features (as well as fix broken ones) then I may have a different opinion.
Just my 2 cents...Good luck.
