The best speaker you ever heard?

Dear Argyro, I think that you have to read once more the headline of the thread. It is "the best speaker you ever heard". That seems to be only a personal opinion, isn't it?
When it comes to listen to music using other speakers, (Tidals maybe), who knows, I may like them better!
Until that time, I'm staying with my beloved SHL-5s.

Try gamut s9 speakers they sound amazing. The price is not cheap not by far better than anything I listen in my 25 years of music.

Vandersteen 7's playing analog 50's jazz. Quad ESL-57's are a close second, but 1/100 the acoustic power, and (literally) half the bandwidth. I once owned a pair of Quad's paired with B-139 based transmission line subwoofers and Sequerra T-1 ribbon tweeters. This solved the bandwidth problem, but not the acoustic power problem.

Both of these speakers display a delicacy with midrange and high frequency sounds at the " pppp" volume level that I've never heard elsewhere. Both are remarkable loudspeakers. (BTW, Richard V still considers Quad ESL's as his reference).

Dynaudio Sapphire. Doesn't matter who says I swear by the Dyns although this particular one is not as costly as some of the names mentioned here. Unfortunately, my pockets aren't deep enough to go beyond that. I am sure the Evidence Master would sound much better but that's all there is (quoting Dynaudio's tag line). I used to build DIY speakers or do speaker mods and what I found is that some of those astronomically-priced speaker manufactures actually uses OEM Dynaudio drives. I am not going to mention names since it might piss some people off.

About the Dynaudio Sapphires, if you don't mind.
I love the Dynaudio sound but I have to sit 8 feet from my speakers (they are on the long wall of my 20 x 13 foot room).
I had Aerial 10Ts & Wilson WP6s right here & they were fine. So do you think the Sapphires would fit here?
