I had on loan a pair of Extrema, owned by an importer friend of mine. After several months, I realized they were one of the greatest speakers I had the pleasure of having in my listening room. They loved the juice. My 2 best powerful amps at the time, a Krell KSA 100, and a Threshold Stasis 2 , did ok, but it wasn't until I acquired a Crown Macro Reference, did they come alive and provide me with some of the dynamics I heard from my horns ( still not the same ). But, a wonderful speaker. Enjoy ! MrD.
