Andersd...My amp is the GFA-5503, which is the three-channel version of the GFA-5502 that you probably want. These amps are rated at 200 watts into 8 ohms, and 350 watts into 4 ohms (which is what the MG 1.6 are). I paid only $875 for my amp which was "B stock" (demo or mfg repaired) and it came from an authorized dealer with full warrantee, and I have no problems. (Someone "broke it in" for me, if you believe in that).
Magneplanar speakers are a very "easy" (resistive) load for the power amp, so I doubt that some of the very expensive amps would do much better than the Adcom when used with Magneplanars. If you were driving the MG 1.6 with the Adcom you would have a valid basis of comparison if you ever were to consider one of the very high end amps.
