Hello @jeffreypi I have experience owning the Vandy 3s and hearing the Ohm at my friends. The Vandy's are a lovely speaker, but don't really rock out or play loud. They even had warning lights that came on when I did.
The Ohm's were music everywhere as opposed to nice soundstage and imaging. I have heard omni radiating speakers many times and my ears never felt good afterwards.
If you liked the B / W pair I would look at a used pair of N803's. I still have a pair of these in my vaca home and they sound smooth and great. In my mind, the N line of the 800 series by B/W was the smoothest.
