My current set-up is a pair of M2 clones with a Crown DCI 4x2400N. I got rid of my pre-amp and DAC and just use a BSS BLU-USB connected to my amp with a Cat 6 cable, nice and simple. My Mac keyboard is the volume control and I have a Furman RS-2 remote control panel and MP-30 to turn on and off the amp. The amp is in my basement right below the speakers. It had really loud fans so I had to move it to a different space.
To sum it up I would never do a four way active system again.
