The Maggies 1.6 will benefit from a moderately powerful amplifier with a high damping factor. In this arena I enjoy a couple of class D amplifiers that use the ICEpower 500 ASP module. Have a look at the Bel Canto Ref 500M for example. I have reviewed the 500M bigger brothers (1000M) for PFO last year, and the 500M are said to sound even sweeter than their more powerful brothers:

Another very nice amp with the same module is the Rowland Model 201 mono. Its performance gets even better once you power it through a Rowland PC-1 rectifier and conditioner. . . or you can use a PC-1 unit on each amp.
