The best speaker you ever heard?


In my opinion, the speaker is by far the most important part of the audio system. After all, it is the only part you hear. OK, the other stuff really matters a lot, but without a great speaker... No go.

I am a bit 'speaker-obsessed' I guess, and now I am wondering: What are the best speakers you have ever heard, and what made them the best?

Magico S5. I must admit I'm a huge Magico fan currently owning the V2's. This past weekend I had an extended listening session with the S5's, and have to say after 30 years in this hobby I haven't heard anything this good. In summary they have the expected magico transparcy but with more output at the low end. They seemed to do everything well. Stay tuned these are game changers(my biased opinion).
my dc10 instrument 8PS power accuracy and engaging..Next is my big TAD's they just need more power but are amazing too!
Wilson's Sasha, Sophia, Vandersteen's 7s are all excellent. YGs Carmels, though are best sound I've heard for under 50k. (with Spectral 260 amp)
Analysis Audio and Krell LATs,One of these years I have to attend RMAF so I can hear more of a variety of speakers.But these are the best that I have heard.
