I currently have a setup of: Denon AVC-A1 amp Main and Centre M&K S85 Rears SS150THX During a particularly loud session of The Fast and the Furious. My amp cut out and when I truned it back on again my S85 centre had blown !! 1) Can anyone tell me why this had happened 2) Will buying a better speaker give me a better chance of avoiding this happening again. I am thinking of going up to the S150 s at the front (one at a time as I am not rich just Home Cinema crazy). So I need help. What is the major difference between the S150 or the S150P. And is it worth me paying the xtra or just buying the S150 and a seperate power amp. Also worth noting beofre you answer is that i will only be replacing my centre at this point and then the other satellites when finances allow. Will this cause me any matching problems? I know I'm a waffler but please help ! Darren.
