Two Questions...

I have my mind set on the Bose Acoustimass 16 Home Entertainment Speaker System...

...the "flagship 6.1-channel speaker system" from Bose.

First question, are these worth the price tag? Is there anything else that compares to these speakers? Am I just paying for the name? Are these the best currently in the market? Give me the run down.

Second question, will the Denon AVR-486S: 7.1 CH Home Theater Receiver be good enough to take full advantage of the Bose speaker system?

The speakers are compatible with A/V receivers and amplifiers rated from 10-200 watts per channel, rated from 4 to 8 ohms. The Denon puts out 75 watts per channel.
