hi - you've sold me out on Paradigm Cinema 90 along with the Denon receiver. Just returned from the store and the sales representative was a bit *pissed* at my decision. But he said something new now which made me think and thus come back and ask you good folks 1 last thing. His statement: Your receiver for these speakers are under-powered and thus will blow the speakers quickly. If you buy instead a system like Bose, then the receiver+speakers are calibrated by factory and they match. We can do the calibration for you and will cost you $350.00 and will take 1 day to complete.
He mentioned something about resistance of these speakers, etc. Additionally, he also said I need correct DVD or a Blue-ray player. He offered me something (DVD) which is like $400.00 and said that's the cheapest and most affordable option for this setup: Paradigm+Denon. Good folks - kindly, kindly advice. BTW: Kudos to all of you!
In case you were curious, here is a review of the Paradigm Cinema 90 5.1 setup,

The speakers are all 8ohms impedance and rated for 50-100Watts power, meaning, the Denon 1910 AVR is going to power them just fine. If anything, being that they are small speakers, most likely, they will be over powered.
You will need to adjust the settings on the AVR to get best possible sound, but there are plenty or articles and this forum to guide you thorough the process. It is easy and no need to spend the additional $350.
As far as Blue Ray Players go, Oppo Digital makes a kick a$$ product.
Oppo BDP-83 It can play virtulally any disc based media you throw at it and can do it with exemplary quality.
