Soon I will complete the purchase of a Cinepro 2k5II amplifier. The center channel I now own is no match for the hoards of power this thing generates. I need a new center that has high power handling and have narrowed the potential choices down. The M&K S-150 is my top choice. However it is a 4-OHM center and the rest of my loudspeaker suite are 8-OHM. On a receiver I would NEVER mix loads because many of the resources contained in the amplifier section are shared. However, in the cinepro the center channel has its own board separate from the mains & surrounds. Given my limited knowledge of EE, I think this setup is OKAY for this reason. But before I invest a couple thousand into an amp, I want to make sure it isn't doomed to unstability before it makes it into my setup. Can anyone tell me if this approach will work?
