SF Extremas

The Extrema is one of the best monitors ever made,
the drawback is that they require a lot of power.
I first used them with an Audio research vt200 and they sounded good,what a difference when i changed amplifiers
The Plinius SA250MKIV made them sing and had dynamics to die for.

thanks for all your help. guess ill look for another speaker. the power concerns me.

I used to own Extrema and Merlin VSM. No contest, Extrema is in a different league and VSM is not even close even with BAM, and I am not just talking about bass. Extrema was much more musical and less fatiguing even though they use the same tweeter (according to Dynaudio, there are 12 versions of Esotar 330).

No, VT-100 is not enough, nor will VT-200 be enough. In fact, I doubt any tube amp can do justice of the speakers. I powered them with SF Power 3 for most of the music, but had to run solid state (Pass or Rowland) on some. My recommendation is a good solid state, Pass or Plinius should do well depending on your taste.

Semi is correct. There is no way in history a 100 watt tube amp will be able to power the Extremas.
The Extremas need so much power. The only tube amps that can power them are the big Conrad Johnsons, Jadis or the Audio Valve tube amps.
You need amps like the Rowland 7 mono blocks.
When the Extremas have the power, they sound incredible. The best midrange I ever heard in my life.
That Skaaning midbase is unreal.

I tend to agree with Semi. if you do not have enough power to drive these babies, then you have not heard really good extrema yet.
