I heard them last fall at Lone Star Audiofest. Duke was showing with Richard Gray and his tube amps. Great sounding speakers (I thought they were the best I heard at the show) and a really really good guy to talk to. Show conditions of course, but they imaged very well in a small room and as I recall had great dynamics, body and weight with an overall nice tonality in the way they sounded. They don't come any nicer than Duke as an added plus.
My two cents from the one time I heard them I was impressed, as was the buddy I was with.
