Hi!
Looks like you've already done your research, so I'll just add my 2 cents:
I've owned a couple Denon Receivers, and always enjoyed them. So, my bias is Denon. Haven't touched a Pioneer in a decade, due to confusing set up and controls (surely thats changed), and Onkyo I have always been weary of their build quality.
Have heard that Pioneer package, individually, as a 2.0 system (both bs and fs) and have heard a number of Klipschs'. Yes the Klipsch is prettier, but I guarantee you the Pioneer will sound better!
The BIC subwoofer is crap, however, and that is going to be where next upgrade happens! Think about it, a subwoofer should have an amp, a big magnet, and a sturdy box; a good sub costs money! Enjoy the BIC for a while, and then when you've got another grand to spend, discover what you've been missing!
