I haven't heard the Lorelei's, so I can't comment on them. But we own the RM2's.
First off, I would say that the concerns over limited dispersion with the VMPS
speakers are generally very exaggerated. The speakers sound great even if you aren't
in the sweet spot, say, seated off to the left or right of center, but they go to
an even higher level of sound quality when you are sitting in the center listening
position. The FST tweeter upgrade also widens up the horizontal dispersion quite a
bit according to reports. We have the FST upgrade and haven't had any problems with
dispersion at all. And the limited dispersion helps with reducing unwanted reflections
muddying up the sound.
And the sound quality is just superb, you won't believe the level of detail
in the sound! The voices and instruments come alive with a realistic nuanced sound
the likes of which I have never heard before on any other speakers. For example, a saxophone
wasn't just some lifeless "sound" coming from the speakers any more, you could hear the
air flowing through it, like a living breathing instrument. We could even hear the
plungers (not sure what the correct term is) on sax's topping out (hitting the upper
limits of their travel) as the musician's fingers released them.
This is the kind of detail and realism I'm talking about. It's the closest thing
to having the musicians in the room I have ever heard. And the sound is so sweet and smooth,
not harsh at all. But it's not rolling off the highs at all, it's just that it plays them
in such an effortless silky smooth way. Very easy on the ears.

And the bass... The RM2's have incredibly powerful bass available on demand, and yet
also delicate and precise bass. Delivering what is asked for, and no more. These things
can handle music bass no problem. And for movies, WOW. Low, accurate and LOUD, perfect for
demanding DVD action movies.

I highly recommend you give the RM2's a listen. There is even a 30 day free trial period
where you can send them back for a full refund if you don't like them.
