Ribbon tweeters can be more narrow / more focused / more "beamy" than dome tweeters. I witnessed this when I demoed a pair of ascend acoustics sierra towers with a high end RAAL ribbon tweeter. No the speaker for me, mostly for other reasons.
I really do enjoy the ProAc sound and while the D20s I demoed got loose on the lower frequencies, my ProAc studio 148s are the speaker for me (budget, soundstage, tone, size and frequency response). Try some Soundocity SEV9 outriggers with your 140s. I use them and love them. You can use them if you upgrade also.
