I have been a martin Logan guy for the last 10 years. I owned a pair of Aerius I, then Ls3 and the Theater center. As much as I love the way Logan sounds ( loud and clean ), I hate all the care and maintenance for the pannels and all the electrical power cords running on my carpet. Here is my last system, it may not play as loud as Logan but it does not require a monster power amp as Krell to drive. Plus I believe, the combination of liquid sound from ARC and the wide sound stage of Sonus faber GP will send you to Nirvana. The older I get, the more I pay attention to quality of the sounds not the quantity. It took me 2 years to have enough courage to part with Logan. The road ahead will be a different journey and different type of sounds.
