In your particular situation I second Buconero17 and Swampwalker. I would pay particular attention to Swampwalker's argument as it applies to your setup. Also, with the active Quads where you need longer Interconnects, consider preamps/pre-amp DAC combos that have balanced (XLR) outputs. If you are on a budget, you might want to check this out: http://www.pacificvalve.us/MatrixBalanced.html
