I'm considering buying the Magnepan Mini Maggie 2.1 system (all passive) and being a complete novice that I am to speakers, I was hoping some more knowledgable members here can help me with setup. I hope to pair it with a stereo amp that will be connected to my Schiit Lyr acting as a pre-amp. Would a 2 channel speaker amp work for this 2.1 system? Or must it be 3 channel to connect the subwoofer panel? Or am I wrong entirely? I'm looking at the Emotiva XPA-2. Thanks!
