You chose well with the Vandy 2ce's. I would not consider them 'directional'. When properly set up, they are one of the most transparent speakers for the money. Did you follow the set up for the Vandersteen speakers?
I won't disparage Ohm's, I really like the way they sound, but Vandersteen's are in a higher league In my opinion.
If you want to move upward, get a pair of Treo's-much better than the 3's and much more WAF'able.
I think you should contact John Rutan at Audioconnection. He is an Audiogon member, so you can PM him. He will give you the best information for free, and never pressure you.
