The best speaker you ever heard?

Coincident Pure Reference! Unbelievable speaker system. Within 15 minutes of hearing them I just had to have them. Seriously, my current speaker had been the Legacy Focus, a terrific speaker unto itself. But, the Pure Reference was spectacular in their delivery of music, detailed, articulate, very dynamic and open with no beaming. Walking around the speaker revealed no typical holes or beaming. Soundstage and depth are incredible. Toughest part of making a choice is the ability to get home in your home connected to your equipment to give the speaker a fair chance. That ability very much limited my selection. There any number of other speakers that may be as good such Focal Utopia, Ursher BE-20,Wilson Maxx. But it makes a huge difference to bring it home and see what synergy you have. Do that and you never be disappointed!

Lately, I have concluded that speakers have reached a level where electronic components, ac power, and cables can be more crucial than the speakers. They will clearly reveal the benefits of each. Certainly this is true of my last two speakers, the Tidal Contrivas and the BMC Arcadias.

The best speaker I have ever heard is the mbl 101E as part of a $200K system at the 2012 Newport Beach Audio Show in a relatively large room. That being said, the best I have had in my small room is a recent purchase of Wyatt Acoustics 2.8 using Audio Nirvana 8 inch Alnico drivers. I was amazed at the coherence, immedicacy, presence, and clarity of a single driver. The total price was $1500 and I find the sound much more realistic than speakers I have owned that cost up to $40K.

how come no ones mentioned BOSE 901? LOL HE,HE

The Kaiser Kawero Classic is now the best speaker I have heard. I thought they sounded better than anything else at the New York Audio Show this year, much better than the top of the line TAD, Coincident, KEF, GamuT, or Raidho. I could listen to those speakers all day long...and I had never even heard of the brand before today. Moreover, they were in the LessLoss room, a company I thought was about smoke and mirrors. Go figure.
