Hi, Would there be a penalty on sound quality if instead of using the amplifier and crossover system supplied with the Moviestar 70+ I used my own amplifier for which I have separate amplified outputs to each speaker but only an un-amplified output for the subwoofer? In summary I'd use the amplifier supplied with the Moviestar 70+ only to amplify the signal into the subwoofer (supplied separately from my own system) and drove each satellite using my own amplifier? Thanks Juan
