The best speaker you ever heard?

I don't think that there is any one speaker that does everything "right". Keeping that in mind, i REALLY like Ohm F's when properly set up. Sure, they're inefficient, tough to drive, won't play REAL loud and are really tough to set up, but there is something about a single omnidirectional driver that covers pretty much the entire audible frequency range that is just astounding. I've heard many tall $$$$$ speakers and liked them for specific reasons, but i'll never sell either pair of my F's. Unfortunately, i've never heard the MBL Radialstrahler or the German Physik's model with the Walsh "bending wave" transducer , but i'd like to. I'm sure that they share many of the attributes that i so dearly love about my "hot rodded" F's. Sean

The best speakers I ever heard was a double pair of Magneplanar Tympani's -- driven by 4 tube monoblock amps. Absolutely raised the hair on the back of my neck they were so realistic.

The Hill Plasmatronic is the hottest speaker ever made.

My own Dunlavy V's. It has all the qualities that makes music Music. Although I have not heard some of the speakers mentioned above, but I have heard quite few comparables and I still the V's come out as best IMHO.

Got to go with Sonus Faber Amati Homage...
