i'm very biased. I know what I like and I know what I don't like. Everything out there is pretty good. Some things have definate strengths over others. If had an unlimited budget my tastes could be satisfied with completely different things.
With that, my own preferences. I don't like BOSE cube styled speakers. The 901's are a good speaker but, you'll need more amp than you can afford to make them sound right.
Bose is very bright on the high side, lacks mid range, and the bottom end I feel is flat. Women like small speakers and for what they are they sound good. I would do a paradigm cinema series package in a heartbeat over any small bose setup. And, it's roughly 2/3 the price.
I'm selling my Klipsch setup, and replacing it with Paradigm Studio 100's. I'm selling my Yamaha RXV1600 and replacing that with a seperate amp/preamp, that hasn't been decided on.
I don't recommend using PA equipment in your home system if your into sound quality.
So, once againg this is my personal recommendation, and I have been in this industry for quite some time. I've built custom systems in dorm rooms and multi-million dollar homes. So, i have some experience in this. It really comes down more to what you want. You do get what you pay for. Power filters in my experience have really opened up the top and bottom of the musical range in my experience. I will never go without one again. It's a very inexpensive way of making a good set of speakers really come to life.
