I have the Mofi 10s, love them but they are BIG so not really 'bookshelves'. Very sseamlessly coherent speakers with a natural tonality.
Harbeths are an acquired taste IMO and are picky about music and electronics, the Mofis very accommodating with just about any genre and gear but will reward expensive electronics.
However the 10s have crap resale value, for some reason Mofi have begun discounting them, so if that's important to you look elsewhere.
