I really like the Harbeth 40.2, but they are so different vs. the Magico speakers I own that the comparison is meaningless.
In my own two systems I have the M3's and the Q3's. They are famous for being neutral - very little, if anything, added to the ultimate sound. I thought the Q3 was the best speaker I ever heard in it's price range - until I bought the M3's.
I've listened to nearly all the current models of Magico speakers at trade shows and I like them all - for different reasons and applications. But, they are expensive. A used pair of any Magico, in good condition, might be an affordable option.
