No sadly they were dealer 1 year old demo speakers. I had a set of Dynaudio contour 20i speakers, and did notice a huge difference in sound from then to the 20's. To be honest they didn't change in sound much during the 2 years I ran them. I also had a slight toe in on them so the tweeters went just past my ears. Like you I listen to a lot of Folk female singers, Jazz blues and classical.
I find the imaging to be incredible. There is no overlapping either, you can pinpoint each musician on the stage, and hear them all at the same time. The confidence 20 needs a lot of amp to drive them properly, I am running Sugden MPA-4 mono blocks. 165w of pure Class A power. More than enough. My room is 13 feet wide, 20 long and 8 foot ceiling.
