Speakers in the 5-6K$ region & their components

Hi all,

This is my 1st post here.
I'm a long time audio enthusiast and even worked in high-end audio sales for a few years a while back, but I've been out of the loop for a few years now. I'm looking now for a new pair of speakers in the 5-6K$ range to replace my current Merlin TSM. The type I'm looking for is a 2 way 6-6.5'' speaker, preferably a floorstander. I know many brands and models and went through a lot of speakers in the past, so my question is a technical one:

I'm looking only for speakers in this range which use high end componenets. which ones are there?

I've already done some research, so here are a few examples of what I mean:

Proac in its response range is using Scanspeak D2604 tweeter (48$/unit).
PMC in its "i" series - Seas 27TFFC (45$/unit).
Spendor, "A" series - Seas 29TFF/W (52$/unit).

I can go on and also bring examples of the woofers used and more speaker brands, but I think the picture is clear. These are all quality units of well acclaimed manufacturers, but are by no means high-end units. Which are?
My research brought me this far to the following (All in my price range):

Kudos audio Super 10/Super20: Seas T29CF-002 tweeter (330$/unit) + a version of Seas W18NX (196$/unit)

Marten Form Floor: Accuton C173-6-095 woofer (over 300$/unit) + a ribbon tweeter I was unable to recognize (anyone?)

Merlin VSM (as second hand only): Dynaudio D330/A tweeter (over 400$ per unit) + Scanspeak 18W/8545-01 (173$/unit).

BTW, my current Merlin TSM is using Morel MDT30 tweeter (80$/unit) + Morel MW166 woofer (124$/unit) and sounds wonderful to my taste, despite a considerable lack of bass (being a sealed- box design). 

So, given all that, does anyone have any more ideas for speakers I should consider?
