Arro's shouldn't sound "flat". That should get better with break-in I expect.
I've heard Arro's but never a/b'ed them concurrently with Ohms.
I think the Arros should do extremely well with imaging (for a standard box design) at least at the sweet spot, but I do not think they (or any standard box design) will ever sound like the Ohms IMHO. Ohms image distinctly in their "own special way".
I have heard Arro's that were not set up optimally stack up well against larger and more expensive speakers from PSB and McIntosh that were also not set up optimally. They all sounded very good but could have sounded better with proper set-up.
I've heard other Totems set up better in the past that sounded similar to comparable Dynaudios at the time. I can honestly say that in a/b tests in my house, the Dyns, as nice as they are, cannot touch either pair of Ohms.
