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?

Polymer Logic speakers from polymer audio.
With a diamond cone for midrange, It pretty much puts to rest the 16 pages of recommendation.

Deadly,

Did you actually get to hear these, and if so can you comment some more.
I am really strongly leaning towards them. I talked with a recent purchaser (Bill Powell) who commented briefly about the speakers, but he is probably in listening heaven and not posting comments.

In 1996 or there abouts I had the opportunity to listen to the Jadis Eurythmie II speakers at the Stereophile show at the Waldorf Astoria in New York. Even under the poor conditions of the show, I was astounded with their effortless and dynamic presentation. I knew in the proper room, with proper set up, they would be remarkable in all other areas, such as coherence and imaging. I would love to own a pair.
