$20k top, full range speakers?

Stanwal, thanks for suggesting the GamuT speakers. I have never seen them before. They do indeed look beautiful and if they sound good too I wouldn't mind them at all.
Too bad the S7 is out of my budget

Thanks for the responses.

Audiofreakgeek,
Thanks for your suggesting Kef. I forgot to mention them. I owned a pair of Kef 107 too for about and decade. But they lacked terribly at low volume in comparison the the 104s they replaced. ironically the 104s couldn't play loud enough when I wanted. However, the 107s had a fantastic midrange.
I never heard the 207 and frankly I thought about them as well. How do they perform at low volume?

Thanks for your kind invitation, but no trip planned so far.

Onhwy61,
Thanks for posting.
Right now I have an Icepower type amplifier (500w x channel @ 8ohms) and capable of driving my Vienna Mahlers quite well.
Your observation on speakers costs and speakers environment in interesting to me. It has been the major reason why I am thorn on the choices. I know that a wonderful speaker can sound bad in my circumstances. Large living room but L shaped, and the left speaker will be set near corner 3 to 4 feet from walls, while the right speaker sits in the open. With the mahlers I use a couple of JL f113 crossed at 60hz because the mahler's left speaker produces a huge bump down under.
When I had the kef 104aB I could place them anywhere and always loved the sound. Perhaps because they had no ports? For that reason I started looking for sealed speakers and it turned out be quite difficult in these days. To make my journey more challenging the speakers must be beautiful to look at, not just good sounding.
A friend of mine from Italy heard the opera Tebaldi and tells me are wonderful. But all those drives can they be an advantage in my room? These speakers have no port, only passive radiators like my beloved 104ab...

Thanks Reynolds853,
I wouldn't mind auditioning La Folia at all if i can i will. The mahlers I have now are beautiful and I don't want to downgrade in that department. So, i find the Cantons not appealing to me. Obviously aesthetic matters are purely subjective.

Do the Salon ii play well at low volume?
Thanks

Well, I am reading/looking about the so many great suggestions I am getting from this post. for that i thank you one more time.
Still, I found another speaker that aesthetically is not my type, but certainly from what I read it is quite interesting, it reminds me one of my first speakers I was looking into (Opera Tebaldi), which is the Genesis G5.3 with its dipolar configuration.
I cant find much of user's opinion about these. Anyone here ever heard them?
I read their web site pages but i cant find any statement whether it is a sealed or ported design, i must have missed it.
