I can't vouch for any of the other speakers on your list, but I just got my CBM-170 SE's yesterday and listened to them as much as I could and they sounded absolutely amazing! These replaced some PSB Image 2B's (nearly identical to the B25's) and, to me, there is no comparison. I believe there is definitely something to be said for a neutral frequency response with good off-axis performance. Granted, I'm not through critiquing my new speakers, but based on what I've heard so far, I think they will definitely be keepers in the end. I threw all different genres of music at them last night and they performed exceptionally well with all of it and they go LOUD with ease. I have them in my bedroom and bass response is good, but I will eventually get a sub; I could hear the lower, sub 50 Hz frequencies, but they lacked oomph! Ascend even has some B-stock 170's right now for $306.24 + $20 shipping. Mine were B-stock and all I found was a scuff on the bottom of one and a light scratch on the side of the other. Good luck in your search.
