The best speaker you ever heard?

The best speakers I have ever heard are the ones I have owned since 2005--PSB Platinum M2 monitors. They are so good that I am trying hard to replace them with much more expensive speakers but can't let them go. Very frustrating, but with every system upgrade, they get better and better. Very fast, transparent, sweet when necessary but with a real raucous nature when called upon.

Not to go off topic but I've compared exotics to the PSB M2s and still prefer them. I agree with the skepticism about price in the previous post. This weekend I'm listening to SF Guarneri Mementos which if I buy will automatically become the best speaker I have ever heard, in my limited experience.

Mceljo. I will buy the Mementos only if they sound better in my system in a home audition than the PSBs. In that case, the Mementos will be the best I have ever heard; if not, the PSBs are still champs. Thanks for your input.

PSB M2 Platinum monitors exhibit great energy, excelling in everything from acoustic jazz, female vocal, to large-scale symphony orchestra. While the Platinums are the top of the line, the other models have been well received. Canada seems to create great speakers even if some are assembled in China.

Sonus Faber Fenice. I heard them only briefly at a dealer playing a large orchestra and chorus. Positive: realism, effortlessness. Negative: limited production and price at about 140k euros. Ask for a pair for Christmas and don't forget a good front end. For the real world: Sonus Faber Guarneri Mementos.
