Welcome to the 21st century. ;)
The FT-2000 doesn't have cascaded filters because the IF DSP works as
the second filter. This certainly isn't a design flaw, although one
could debate how well it's implemented in the FT-2000.
Oddly, one of my friends, who is a traffic handler, DXer and contester,
sold his FT-1000D after getting a FT-2000. He says the performance is
comparable and the 2000 is less fatiguing to listen to.
