Harmon is building a Stan Warren dual mono buffer like mine. A ten amp bridge is a good thing in this application, the bigger the amperage rating on the bridge the lower the power supply impedance will be. In other words the bridge won't be a choke point for current or voltage delivery in volume or speed. With a properly constucted supply and board layout, this buffer has a greater than 30mHz bandwidth, superb settling time and slew symetry,with .003 THD+N
