I have owned the Contour 20i's for 2 years, and I love them. But they are right at the edge of having a bit too much treble energy. The Heritage and Black Editions, both of which use the Esotar 3 tweeter, might push the treble too far, so I would definitely audition before purchasing. The same goes for the Monitor Audios. Lastly, the Blacks have 10Hz less bass extension compared to the 20s (50hz vs 39hz), so you might ask yourself if you're ok spending 8k on speakers that could possibly sound lightweight... I personally really need full output below 50hz. If you are interested in Dynaudios, I think I would hear the 20i's as well compared to the Monitor Audios...you very well might prefer them more.
