My local dealer set up Maggie 1.6's with a Manley Stingray in his used equipment room, and the sound was incredible. I would not have thought that 50 Watts UL would have done so well. I had owned the 1.6's twice previously and tried several tube amps that offered near 100W channel, and didn't have the dynamics that the Manley had. This one will drive the 1.6's without a doubt, and although a bit more $$$ even pre owned than you may want to spend...would be worth it for a quality made integrated, that works with the 1.6. El84 tubes provide tight, punchy bass and tubes are good sounding and affordable. A change of its 12AT7 input tubes to TFK or Mullards will take it up another notch
Good luck!
