I have virtually decided that I am going to get the bose acoustimass 10 speaker package, I have listened to them and thought they sounded great, although I know there are some people on this site that dont like them, that's their choice. The problem is which amp/receiver to get, as the bose sat speakers all go through the subwoofer which is only 5.1 not 6.1. I was considering the marantz 4300/5300 & the yamaha 630. the latter being preferred, but all these are 6.1 receivers which would probably be a waste of money seeing as I cant connect a sixth sat to the bose sub. I know the marantz do the 4200/5200 models but are they much different to the above and also do yamaha do an equivalent model of the 630 but only 5.1? Which is the best way to go, get a 6.1 & not use the sixth channel or get a 5.1 receiver, if so which would be more compatible with the bose speakers. I will use the system mainly for films, but will also use occasionly for music also. All advice welcome as I cant make my mind up. John.
