This thread is pretty old now, but if anyone is reading this now I have learned more about powering Maggies lately.
The folks on this thread who said that my amp was underpowered for the Maggies are absolutely correct. I hooked up a pair of PSB Alpha speakers which are 89db efficiency rating (twice as efficient as the Maggies). I put on a CD and very slowly turned up the volume until the clipping lights on the amp started to flicker, at about 11 o'clock on the volume knob. (I would have done this test with the Maggies, but they are at Magnepan being repaired).
From this I would guess that if I set the volume knob at 9 o'clock or so driving the Maggies, I am probably at or near the threshold of clipping. I wouldn't have thought it possible, but there it is.
I am going to find a much beefier amp now.
As for the CD player, I "fixed" it by adding DAC for now.
