I have my FM3, lap top and CD player going out to a Yamaha MG10 mixer, from there out to HS8's or head phones. This way I can control the volume and tone of the laptop or CD player without effecting the tone of the FM3 and my guitar. I only play at home and this works well for me. One other note I have a Yamaha sub but no longer use it, I found that I didn't need it with the FM3 for me it muddied things up more than it helped.
