I have heard most of the speakers mentioned here and owned a few, most notably the Martin Logan motion 60 XT and the Vandersteen 2CE. All are good suggestions. Depending on your room and placement possibilities I am sure that most but not all will work. Speaking of the 60 XT, I thought they were very good. They were the main speakers in my family room home theater. I also listen to 2 channel music there as well. I found them to be a bit bass heavy in that room and replaced them with the motion 40’s. I prefer the 40’s. Still have plenty of bass (Without the sub). They are very quick and punchy. Put them on sound o city outriggers. Currently listening to Steely Dan Aja on them While I type.
The best live in-store live demo I have heard was in Deerfield Beach, Florida. While walking back to the hotel from the beach we passed a shopping center that had a stereo store on the main drag. The windows were tinted and I was afraid that it might be a car audio place. Went inside and it was a beautiful little store. The owner played the Maggie 1.7i’s Driven by a 40 W per channel Prima Luna integrated tube amplifier. I was not expecting much, as I had heard that the Maggie’s were power-hungry. The sound was incredible! It was one of those rare “you are there“ experiences. This was in a small to medium sized listening room, but the largest room in that store. If your room placement allows for them, I would definitely addition the Maggies!
