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?

Have not read the whole 14 pages so I don't knoe if mentioned, but I heard a couple of MBL speakers (driven by MBL gear) recently and I doubt anything can sound that "real".
My Wilson Alexandria's with Audioquest Everest and Sky interconnects driven by SH-833 Monoblocks and my 27 watt Ongaku amp, 20 pounds of silver baby. May upgrade the cables though.
Price no object: Heard the MBL Radialstrahler 111E at the HK Hi-Fi show last year and they are definitely the best I've heard. They need a big room and an even bigger wallet though.

Keeping feet on the ground (barely): ATC SCM100 (Active). Possibly the best midrange I've ever heard.
