Onkyo tx-sr875 set up....matching speakers/connection!

[Gravion2005]

Ok i already took back the 605 due to it's less than stellar video conversion. I should be receiving the new 875 by thursday via fed ex at the latest. So NOW i've tried to match this with the speakers and i can't. I already took back the kef and i was checking fluance but those speakers don't match up with this receiver as according to u guys, the center speaker and the 2 matching fronts should at LEAST be the same watts as the receiver but this receiver is 140...the brown cabine fluance fronts go up to 160 but the center is 100 and i read mismatching sometimes doesn't work well with sound transfer or calibration. The bose speakers only go up to 100, the klitch quintet 1 and 11 series don't do 140 either. I need to match these babies up PERFECTLY my dear experts...so what's say u all? That is all i need then the best way to connect it. I want to do 7.1 this time since i paid for the technology so i might as well hook it up, my room is 20X12. Much appreciated people

BLURAY RULESSSSSSSSSSSSSSSSSS!!
