IME, the Ohm 100s are a bit more neutral than the Vandy 2 series, which -IMHO- has slighly elevated upper bass and slightly rolled presence/treble. Each of those two qualities is subtle, but taken together the combo of these two characteristics make the Vandy 2s seem just a touch "warm" to me. Tonally, the Model 5 or the Quatro is closer to the Ohm - just flat neutral. Of course, those Vandys have powered bass modules, so there's some "wiggle room" in their tonal balance - but when set up for max neutrality, they're pretty spot on, IMHO. As are the Ohms.
Imaging is a different story. The Ohms bring a certain "weight" to the images that I've heard only from omni designs. This is a really significant difference and separates the Ohms from most other speakers that I've heard. In other respects the Ohms and Vandy 2s image similarly, though I feel that the Ohms may go a bit wider in projecting believable sound sources outside the speaker than I've ever heard from any Vandy speaker. There are enough variables here - I've heard a half a dozen Vandy 2 set ups over the years, but never in the same room/system as the Ohms - that YMMV.
I'd mostly agree with Mapman, but would beg to differ in the comparison to MBL, as the 101s can create the illusion of 3d space extending into your lap in a way that is, IME, virtually unique (and certainly beyond what I get from my 100s in this regard). Actually, to be more accurate, I've heard some minimonitors that can also create the illusion of images way forward in space. The ProAc Tablettes come to mind. Either way, the Ohms are more limited in this regard than the best imagers I've heard.
Hope this helps.
