I had a pair of MMG's and went to the 1.6s. The cliche about Maggies being placement sensitive is true. I'm agnostic about the cliche concerning their power hunger(at least at classical and jazz amplitudes). You mentioned "congested". Might that congestion be related to their diet. The best improvement with my Maggies came when I went to a low feedback,high current design amp. The 'low feedback' amps that come redily to mind are from Monarchy,Van Alstine,and Sim. I'm sure there are others that amp experts here can mention.

owners of this fabulous speakers whats the "average" burn in time for these planers?...I got a brand new one with only 8 hours of break in time,sound abit congested right now but I heard these at a audio store which the owner mentioned it took over 100 hours before the true potential was present.Is that about the average time?..
