The best speaker you ever heard?

Hard to say since there is no one "ideal" speaker around.
Vivid "Giya' comes close. In addition I would list speakers I love for the "close to the real sound" quality they all have (in some cases it had to be together with the electronics used at the moment),starting with the more expensive and going down:
MBL 101, Original B&W Nautilus, Wilson Benesch "Chimera", Vandersteen 5A Sign. Some Sound Labs should be added as well.
For the "small" speakers it is Sonus Faber "Extrema", Wilson Benesch "Discovery", B&W Silver Sign.

Paul Hale's Hales Design Group Transcendence 8, powereed by Boulder equipment. Of course I'm a bit biased as we all are in that this is my current system, but honestly I have never heard another speaker this transparent ever. Between it, the Boulder power and preamp, and the Meridian front end, if you put music in, music will come out gloriously. Unfortunately, on the other hand, if you put garbage in, well....

Focal (JM Labs) Grande Utopia EM. IMHO challenges the boundaries of modern loud speaker performance

as previuosly mentioned by some members there is no best speaker -we choose the most important sonic feature to get close to real sound.
from comercial fullrange traditional dynamic speakers mass production (bigger manudacturers,clasical drivers implementation)-
1) the most technical "right" sound Jm Lab Grande EM closely folowed by Stella EM, and not far away other and older 2002year utopia. all of theese bunch are very warm sounding speakers also.
2)the most imediatly , live and dynamic sounding speakers- older Wilson audio speakers. Some of Peak consult and verity audio top line steps in the same sonic features.
3)the best soundstage and calm smooth,soft sound (opoizite to wilsons) MBL 101E with soundstage performer Kharma Eq.

i didnt find comecial speakers which had all theese features in single package.

from small speakers very musical and big sounding(but coloured) speakers Sonus faber Extreema, more precize -Jm Lab Diablo Utopia, average medium between theese both would be dynaudio special twenty five.

i didnt counted many small manufacturers just the main ones.

Anyone evr hear Royd speakers?
