5 legendary speakers?

I have recently read Ken Kessler's old but still wonderful review of Sonus Faber Extremas. He ends the review by saying that "It is one of a handful of loudspeakers which qualify as legends."

I own a pair of Extremas, and I agree with Kessler's statement. Now, I am curious to know what other audiophiles consider "legendary speakers" based on their own experience. I would define legendary speakers as ones that are path breaking, that redefined the frontier of sound quality that is affordable by the average audiophile (I know, it's a vague definition). Let me give my list of 5 legendary speakers. These are all old speakers I would live with today.

1. Quad ESL 57
2. Klipsch K-Horn
3. Thiel CS5i
4. Sonus Faber Extrema
5. Sonus Faber Amati
