"But, more importantly is that having the crossover before the amp automatically reduces intermodulation distortion of the speaker system. Each driver in an active speaker will have its own matched amplifier. There is no reason to incur the cost of a general purpose amp that is designed to power all manner of speakers."
That's not true. There's always a cost for singling out 1 specific potential problem or spec, and highlighting it in a way that makes it look like its more important than the others. Following that logic, a cheap pair of active speakers should sound better just because the active nature of the xover, than a cost no object design. IM comes up in all areas of component design, and is not isolated to one specific part. Just using an active speaker will not eliminate IM distortion. It can't.
What makes a great component is the designer; not the design itself. There's a reason most people will buy a Pass or Ayre amp (Or whatever else is equivalent), than settle for a generic powered speaker, active or passive. Better sound quality. Same thing with speakers. I remember the last time you brought this topic up Bob, you mentioned Vandersteen speakers. I forget exactly what you said, but your idea would have made the Vandersteen speaker loose its time and phase characteristics. You didn't have a problem with that. I do, because that's the whole reason you buy them in the first place. Vansersteen goes to great lengths to eliminate FIM, by the way.
I'll ask you the same question that I asked you last time. You couldn't answer it then, and I don't think you can answer it now. Give us an actual example where a specific active speaker, that you recommend, can outperform a separate amp/speaker combo made by top designers in their respected fields? If you'll notice, I'm not putting too many restrictions on what you can come up with, including cost, so it should be an easy question to answer. I've made this comparison many times and have yet to find any evidence that would suggest an active speaker design is superior, or even equal, to a well matched amp/speaker combo.
