I have had passives in past and now use ATC Active 50 towers with upgraded anniversary amp pack. I agree that if you are interested in tweaking your system to get a particular sound then having separate amps seem to make sense. I immensely enjoy my active system and have tweaked it by having professionally designed acoustic wall treatment, buying the best power supplies and isolation transformers along with hi quality sources and electronics. I can’t see how anyone can say that having an active crossover designed specifically for the drivers is a great if not the best way to handle the speakers. I can’t speak for other speaker companies amps, but the ATC line are top notch and once again fully optimized for their drivers.
