I bought a Pioneer VSX-D811 - have really tested it out. it appealed to me because a) 100W/channel and b) 7.1 sound, so that 6.1 discs get "more natural rear centre" sound. i've just found out that the marantz sr5300 can be obtained for around the same price. should i return the pioneer and get the marantz. the marantz is only 90W/channel, but i don't really mind about 10W too much (but still a little!!). the main thing holding me back is that the marantz can't split the rear centre into two speakers for a better sound. does this 2x rear centre really sound better than 1 x rear centre. will 90w v. 100W make a difference. is the nuance and features of the marantz better. some help would be nice, so i can return the pioneer on monday IF required.
