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?

JM Labs/Focal Mezzo Utopia Be's...that was a few years ago. With Simaudio flagship monoblocks. The new EM Utopia is supposed to change high end speakers forever, at least for Focal...until the patent runs out :)
I`d second JM Lab. Nova Utopia BE is by far the best speaker I have heard yet. But JM-s are very picky about upstream components.
Camdenyard,
I think you mean Alto BE.
