My 2.1 music/HT system is active. Can't imagine doing it any other way now. I looked at the Mackies (HR824) seriously, but went with JBL LSR4328 DSP controlled instead. I was told by Ethan Winer (Real Traps) that he uses the Mackies in his HT and thinks they're great speakers.
I can highly recommend Blue Jeans cable for balanced ICs: http://www.bluejeanscable.com/store/balancedaudio/index.htm I use the Belden 1800F.
