The best speaker you ever heard?

The variety of answers in here prove one thing, tastes differ and opinions are opinions.

I myself do not have experience listening to super high end speakers but I own the modest F208 Revels.

For me many speakers can sound marvellous function of their embeddings in the acoustical field of the room....All speakers are not equal for sure, but most speakers were used in badly acoustically controlled room.... Then unsatisfied people upgrade the speakers instead of treating the room … The rest is audio reviews and marketing history... :)

In my humble opinion is a DIY project.
It is a line array project made with 9 Jordan Eikona drivers for each speaker.
It's also a crossoverless design.
Outstanding scene dept, with a powerful, quick and dynamic sound.
The total project cost is quite high, yes, but the final sound is mindblowing.

Tidal 'Arira' ..just amazing
