I don’t agree that you can’t get a good speaker for $3k  for if you have good subwoofers which I do Svs sb3000 the Amphion 3s is a very  detailed well built speaker at under $3k , and  I always mod the Xovers for rarely does a   Company put good components in a Xover unless you are spending over $10 k on average from my 40
years in Audio they look to save money and most never even compare or know what modding or upgrading is ,the use Chinese 
junk ,ceramic resistors ,keep that in mind ,instant improvement.

slightly used harbeth c7es3.  recommended for you to investigste based on prior ownership.  

I too own the excellent but  a hidden secret in the USA .they just sound like music thst is probably why their 1-18, and 2-18 
which are the industry standards now in the recording industry for 
monitors for mixing,editing sound tracks good or bad they let you know what is on the recording  they have so much potential I replaced allthe wiring with Neotech Occ Teflon copper wire the excellent Jantzen Alumen and clarity csa capacitors Cornell bypass caps . Worlds best path audio resistors and Mundorf evo loudspeaker terminals  these Seas drivers ,and rear passive radiator reallyfil out the bass that does honest low 40 hz
i could not find a better speaker at double the cost .
with the Xover upgrade excellent detail but more more lock on imaging having the time aligned wave guide very easy to place in any room .

The latest Vandersteen 2CESig 3 would have to be in your consideration. In its latest form, it uses the patented Five A series woven cone midrange/ Tweeters the word is spreading nicely. A Fact, this series is the best selling loudspeaker in Hi End history.
