My choices would be as follows:
1. Magnepan LRS+

I have these, as well as several Harbeths, and had the LS50's several years ago. They're all superb - but - I really prefer the LRS+ with the right electronics and set up. Both these and the Harbeths are very hard to beat - though, I think with the right set up... the LRS+ are about as good as it gets... no matter what speakers you chose. They are truly "giant killers" for modestly sized rooms and can be easily moved for listening... and out of the way, when not.
2. Harbeth P3ESR XD

The Harbeths would be my close 2nd...
