Need some advice, I have sda2.3's . This is my first experience with a speaker with two inputs I have a pretty good understanding of the hook up but. Can I use my Mac 7300 and Mac2105 for this purpose. My pre-amp Mc-32 or Mc-26? I have a Marantz 250 amps and a Marantz 3200 pre. I have a Nad c375bee int. amp I'm using for my Sda1 and Sda2's. any suggestions?
