There's nothing wrong with Paradigm speakers, though I personally feel there are better values out there for similar or better quality if you really look. Still, they're really nice and I'm sure you'll love them.
But the SUB. PLEASE seriously look at the SVS PB10-ISD before you waste a dime on a Paradigm sub. The hype is absolutely deserved. I am very familiar with the PW2200, which is a fine sub and it blows away the PDR and PS series -- but my PB10-ISD stomps the PW and for WAY less money. Do your research, you'll see that all these people and independent reviews and measurements can't be wrong. (And I'm a professional full time audio engineer by the way. I do both live sound and studio recording. My ears are my life, and they've served me very well so far.)
Look at it this way. You say you won't buy anything without listening to it first. OK that's a common and reasonable statement. Would you rather listen to something in your home, or in some store where you can't be sure the sound you're hearing will translate to your room, or even be sure the salespeople have set the equipment up right? SVS has a 45-day no questions asked money-back guarantee. So get the PB10, listen to it in your room, and if you don't love it, all it cost you to try it out was shipping charges. Consider it a 45-day rental! And I seriously doubt you'll want to part with it after you've heard it. These internet-direct companies like SVS, Hsu, Ascend, Axiom, they're amazing. Since they have a fraction of the overhead the big retail companies have, they can sell fantastic products at crazy low prices, and still provide great customer service.
If you're still not sure, check out their web site
http://www.svsubwoofers.com. Call or email them. You can speak directly with one of the owners, Tom or Ron, and you'll see that nobody provides the kind of absolutely crazy customer service these guys do. They'll bend over backwards to make you happy.
And no, I don't work for them (though I'd love to). I've just never seen a company care about their products and their customers like SVS does. There ya go.
By the way, Hsu subs are amazing too (I have a VTF-2 Mk2, love it). I just feel the PB10-ISD is in a class of one and can NOT be beat for the price or anywhere near it.
