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?

Now Fred, you have been to my home a few times and know that my speakers are the best there are :^).

Please post results if we don't catch each other on the phone before hand.
The best I've heard (and I bought them) are the Avalon Eidolons (when carefully matched to appropriate electronics). But, I have not had an opportunity to hear the Sound Labs, Kharma Exquisite or Rockports, among others. Still, I love what the Eidolons can do.
I've heard many great speakers including numerous ones I've purchased. However, what I personally find affects the overall sound of a high end system the most is the quality of the recording. Yes, you can use the same media and easily perceive differences between brands of speakers. However a great mastered recording can make even a meager system sound quite good and a great system sound incredible.
The Von Schweikert VR5 with Hovland upgrade, powered by the Spectron Musician II SS amplifier. This combination will give "cost no object" systems a run for the money!
