There is a simple solution for your needs and one integrated that CLEARLY cream all the options offered above - the DK Design Group VS-1 Reference Mk. 3 or the Signature. It is perfect for driving Totems and Sonus Fabers.
Here is why:
1. The DK has enormous power output, 800W into 1 ohm before clipping.
2. Perfect square wave response at 1kHz, therefore very accurate midrange reproduction.
3. Incredible dynamics - your Sonus Fabers will sing like never before and dissapear into a 3D soundstage.
4. The DK has a tube pre-amp section creating very nice dimesionality and smoothness, but without sacraficing dynamics and impact.
5. I challange you compare the DK to any of the above mentioned integrateds. It will totally smoke them.
