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?

If vitus signature is that good then I want to hear it because the soulutions is the most natural non fatiguing sound I have heard in my like. I also want to here the Kronzilla integrated from KR audio. It's supposed to be very good.
Have you guys heard the Rowland, Boulder and Ayre reference amps (the newest versions?).
I've heard Boulder I don't know if it was the signature high end. I thought it was ok. I haven't heard vitus or Ayre.
I liked their signature high-end but I didn't love it. When I heard the price I was in shock.
Calvin, yes having heard the Soulution 501 mono's & 520 pre, I would rate the Vitus SS-025, SS-102,SM-102 monos & SL-102 higher. The Vitus Sig series gear has more control & sounds more organic to my ear. Soulution also don't have any comparable product to the SIA-025 integrated. The Soulution 530 integrated is huge! Though the Soulution 541 sacd player's msrp suggests it should have the wood on the Vitus SCD-025mk2 (atleast on SACD). Better? Probably, but $20k+ better?
