Who is using the Linkwitz LX Minis? What amps are you using? Digital signal processing?

What preamp and amp combo are you using? Is anyone using a distributed array sub system, and if so how do you like the combo? Are you using  the digital signal processors that they recommend, or are you using an analog active crossover? Did you buy a kit, and if so from whom, Linlwitz or Madisound? Recommendations?
