I listened to many speakers, including the ML Ascent and Aeon, before deciding to buy the Dali Euphonia MS4, CS4, and RS3. I definitely agree with the previous response that the choice is very system dependent and taste dependent.
I really like the Dali Euphonia so far. The detail, resolution, and soundstage of these speakers are amazing. They are extremely musical and involving speakers, with excellent dynamics. Overall, I have been very pleased. My only complaint is the slightly thin bass, especially for movies. However, I have a very large (15'x21'x17'H) room with openings. This room is a very challenging room for bass. Finding a subwoofer to adequately match the Euphonia is difficult and expensive, and I am still looking.
I would recommend trying to arrange an in home audition if at all possible. This way you can listen in your environment and decide. I have found that every speaker, even very high end speakers, have trade-offs. Just make sure that you can accept the negative aspects of your final selection.
