I went from Maggie 1.6QRs to VR-2 to VR-4jr back to back so I have a pretty good idea of the differences between them. I have heard the Lorelei's at shows and they have always sounded stellar, and Klaus is a great guy so you can't go wrong. I can't compare them directly to these though.
The Maggies have a transparency that just can't be matched by the VSAs, although the VR-4jr comes close. The VR-2 is one of the best values in high end, if you value dynamics and impact, bass, and musicality. Soundstage is good and deep if you dial in the ambience tweeter correctly. The VR-4jr does everything the VR-2 does but better. More bass (but also more linear), more impact, much greater transparency, more speed, great imaging, etc. The imaging, transparency and scale of the Maggies is not bested by these two however.
At the VR-2 price point, I don't think it gets much better in a dynamic box speaker. I love the VR-4jr, but I think it has strong competition at it's price point. Regardless, it is near the top of the list.
Of course I haven't heard the Lorelei's in my room. I would not be surprised given what I have heard at shows if it were neck and neck, or even better. Perhaps someone here has heard the VSAs and Loreleis?
