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?

I like the Magnepan 3.7i. I also like the Vandersteen Treo CT. Both require some quality power.
I have heard them both and they sound stellar.
Some one mentioned Chapman Audio speakers. I heard them at he RMAF a couple years ago. Very, very nice. Relaxed but still involving. A small company in Washington state. They are transmission line so the cabinet resonance is much better controlled then most speakers. You probably noticed that with your adagios.

Thank you all for your recommendations, I’m looking into the relevant websites. The problem with those who sell directly is that I can’t audition, so the only option is a calculated guess. And yet, I’ve learned of some interesting manufacturers I’ve never heard of.

A few words about the main compromise in my price range:

As I see it, there is one main compromise in my price range, which is the very fact that given that level of quality of the components, I’m limited to 2 Way designs. It IS a compromise. Deep bass, the way I perceive it, cannot be generated from a single 6-6.5’’ driver, even with great excursion capabilities and with the very best cabinet design. There simply isn’t enough radiating area to push the necessary amount of air.
For those who prefer the deep bass over the benefits of high end components, there are speakers such as audio physics’ relevant specimens in the price range, the Vienna Acoustics Beethoven grand/baby grand and In the mid 2000’s there were the Von Schweikert Vr4jr just to name a few. They are all made of middle of the road components (some even simpler), good designs and usually decent cabinets.
I used to own the Beethoven grad for about a year. It had wonderful bass and dynamic range, and it’s a fun speaker I’ve enjoyed tremendously at a certain time. However, It lacked the clarity and precision of simpler speakers made of superior components I’ve auditioned or owned and was quite "colored". Same goes with audio Physic (although to my taste they are better, at least the ones from the mid 2000’s which I have experience with).

In any case, I willingly accept the compromise in the number of drivers and radiating area. I do not accept a significant compromise in the components themselves, not at this price point.
Why do you only consider 6.5" driver, why not 8" of equal quality ? The difference can be big.
I'm all for it, but don't know of any 8 inch 2 Ways up to the specks I'm looking for- If you know of any I'd appreciate a recommendation. Also, an 8 Inch driver will have to be of superb quality in order deliver the mid range quality a high end 6-6.5 Inch driver is capable of. There is a price to be paid in large drivers, such as greater mass and more surface deformations.
