Well, I'm all sorts of different types of audiophile when it comes to active vs. passive. I like my passive speakers exactly because I can pick my amp.
If I make an active speaker I pretty much have to give up my analog soul to a lot of choices made for me by the plate amp maker. An A/D converter, the DSP engine and the amplifier.
I also really really want to make an active speaker... so I think I'll get my build on with a center channel.
