I sold my Martin Logan Aries i's and replaced them with a pair of used Sigs. What can I say, the Legacy's just blow the MLs away in EVERY catagory. I was a died in the wool electrostatic owner for many, many years. The Legacy's have freed me from a life of listening to small jazz groups, simple vocals and Harmonia Mundi lute music. The Legacys are MORE transparent than the MLs, WAY more dynamic, more extended on the top and the bass is to die for. I have a few friends who own SIG IIIs too ... what we have found is that the SIG sound their best when driven by tube amps. They are very efficient, so low powerd tube amps work well. One friend drives his with a modified Dyna 70. Don't laugh ... his system makes MUSIC! I use an Audio Research Classic 60, and the amp justs coasts with these speakers. For those who say to use high powered amps with the SIG IIIs, switch to tubes and be pleasantly surprised. Also, for a significant improvement, change out the binding posts for the top-of-the-line Cardas binding posts ... it's an ear opener.
