i have a nad355bee integrated driving a pair of jbl 4311 control monitors in my second system used outdoors in the summer the combo sounds great the amp also drives magnepan 1.6qr's it sounds beautiful also good luck
That these low-to-mid-priced NAD amps work so well with Magnepans indicates that they have very low noise floors, reasonably fast risetimes, lots of current on tap, an even and musical tonal balance, and rock-solid stability into a 4-ohm load.
