Hi Matt,
I would be careful not to confuse the cost of the amplification with the speakers. For $5,700 you get both omnidirectional speakers and two fully balanced DSPs capable of controlling 10 individual channels. In a smaller room where you would not be throwing a party, two ADA1000-5 amplifiers would be loads of power for the LFR1100 Actives. You already know what the passive version of the LFR1100s can do so I would think of it from the perspective that for around $700 more dollars plus some extra amp channels you can take things up one more notch. And beyond that I would put out the challenge that you may not be able actually buy a better sounding pair of speakers for any price.
