Tweaker,
Both are very good speakers for the money. As others have mentioned, somewhat different in spirit though.
I have owned the RM2's and have had a few experiences with the Lorelei's. Everybody is their own movie critic when it comes to this stuff so take my words with a grain of salt.
As you have seen in person, the RM2's are more of a seated listening speaker. When you are in the spot, it doesn't get much better. Klaus's speaker cannot compete with the RM's tweeter and what it brings to the table, if that floats your boat? And the RM2's are much more of a full-range speaker. But that said, if it were my choice, I would chose the Lorelei's. They are an "all-arounder" speaker, that maybe does not excel and any one thing, but does everything very well.
I have not seen Brian's new cabinets, but based on the older version, there is no doubt which is a prettier speaker. Plus the Lorelei's are much smaller and more "waf" if that matters?
Good luck in your hunt.
Regards,
Jeff
