I've searched for posts relating to this and I've found a lot of 'seperates vs receiver'. My question isn't so much if one is better. I would like to know if I were ONLY able to get a receiver at this time (i.e. $800) but planned to use it as a pre/pro in the future does the power rating of the receiver matter? Will a 150wx6 receiver be any different than a 100x6 receiver when being used as a pre/pro? Secondly, does anyone have any opinions on whether the Marantz 7300ose is worth the extra $$$ over the 7300? Thanks in advance. ********UPDATE********* Does power have to be evenly distributed to speakers in a surround setup? What I mean is that I've read where people use a seperate amp for their fronts and the receiver to power the surrounds. If the amp is more powerful than the receiver will this effect the surround effect with more power going to the fronts?
