Danish Lust

Have to admit, I am smitten. Borresen is my next stop. I am looking for help from any among you who have experience with Borresen. My goal is to understand what I can expect in terms of differences between the X6, Z5 and O2 with all things equal, from the room to electronics. I am avoiding a dealer audition (AB) because I do not want to waste their time. I cannot currently afford new Z5 or O2s unless they are pre-owned, so I would only be using the dealer to make my own determination of which I prefer. I suppose I would purchase the X6 from them, but am guessing that that it might not hold up to the Z5 or O2. The used market puts these three within a similar price range where I need to consider each as potential end-game for me. Please, I am NOT looking for alternatives to Borresen or for opinions from those without experience. Thank you in advance!
