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?

Magnepan 20.1 powered by Musical Fidelity KW Monoblocks and Conrad Johnson ACT2 Preamplifier. Oh My God.
ATC SCM 150ASL, I received mine about three months ago and wow they are better than the Salon, Dunlavy SC-V and SC-IV's B&W 801 and any other lesser speaeker I had before. An amazing sense of being there with no compression at volume. Awesome.
sonus faber strads. unbelievable instrument reproduction, at moderate listening levels i heard a 75 foot organ sound as though a 747 flew overhead, and a violin concerto that felt as though it was going to shatter the windows. i felt as if i heard no coloration, just music reproduced as recorded.
Audio Note ANE SEC Signature with outboard crossover filled with 20 pounds of copper foil caps on each channel.
The most natural, open and immediate speakers I've heard.
